1948 GM PD4151 Greyhound Silverside Bus

1948 GM PD4151 Greyhound Silverside Bus

Here is my 1948 ex-Greyhound GM Silverside bus. A PD-4151. It has a Detroit Diesel 6-71 engine, 4 speed shifter on the steering column a.k.a. "four-on-the-tree shifter," and no power steering.

1948 GM PD4151 Greyhound Silverside Bus

The front interior is original as far back as the first passenger seat. She runs real well. We added Maxi brakes for safety. The rest of the General Motors coach is converted to a motor home. I would like to find Dogs to put back on the outside, and do her up as original. We converted her to - ground, and updated the regulator.

I love taking her out, people just stop and stare when I go by. The shot with the tow truck is when I first got her I had to pull her out to get batteries in her and change the starter motor. She came right to life. I will send more photo's as I get them scanned.
Have a super day!

What kind of info do you need about the engine? Is it the 6-71 Detroit? It probably has two fuel tanks, and is a 4 speed on the steering columb. None of the gears are syncromeshed. Reverse is Put it in first, press and hold the reverse button, and drop her into 2nd. What do you need to know?

Robert Baker | Jun 24, 2010 | 7:52 pm

When I was in the navy in the 1950s, I used to ride the Greyhound bus back and forth from San Francisco to San Diego. The Silverside was the bus I usually rode. When I sat near the front, it seemed to me the driver used to pull a small lever on the shifting arm that gave a pronounced "click" when changing gears. Always wondered what the purpose of that was. Was it a "split rear end" and actually gave the transmission eight ranges rather than four?

Charles Steadham | Jun 24, 2010 | 7:53 pm

Does anyone know what became of a 1947 GMC PD3751 bus that I used to own? I believe the "serial number" was "153." At the time I owed it, the "body" paint was light tan. I drove this bus out of Florida with my band between 1970 and 1975 then sold the bus to a rock band based out of Colorado. I lost track of the coach at that time. The bus had been beautifully converted to sleep eight people (although we shoe-horned ten into it every night).

Dr. S | Jul 23, 2010 | 1:55 pm

I'm looking for either a current RV conversion or an example of one suitable for conversion to an RV old (I believe the correct name is "Super ScenicCruiser, though I have also seen it referred to as a ScenicCruiser. In any even it is the full two level coach with the driver's seat and if I remember correctly two rows of seats on the driver's station level and then a second level one or two steps upward to the rest of the bus. I'm not sure of the original engine(s) employed as I have heard stories of them being two large bore straight sixes driving though a combining transmission to both rear axles though some have reportedly been converted to 8V72 diesel. Once agai this is from memory but I believe I have been told that they would accelerate on both engines and then on the level roadways of the midwest shut down one of the two engines as the power would not be required for level roadway travel. When they reached the Pacific Intermountain West they would reengage the othe engine to transit the Continental Divide. Additionally anyone who can provide reference materials would be greatly appreciated. It is my intention to use it as an RV but with solar dark glass in the windows to avoid the RV look and to give it a traditional cross-country bus appearance.

Paul | Aug 30, 2010 | 5:44 pm

Great looking bus!!! I'm an auctioneer and have the possibility of offering a 1948 Silverside. I'm told it hasn't been started for about four years, it does have the original interior; although some of the seats have been removed. The owners tell me they are "stacked" away. Hope I get the chance to sell the bus, I'm really not far from you.

Have 1948 PD3751 Silverside bus - shifter bolt broke - seemingly impossible to get to the bolt to repair. We've heard that we can convert from column mount to floor mount. Does anyone know where we could get the appropriate parts? Have been told the 'city bus' version was floor mount.
Thanks Nick

DeserTBoB | Oct 11, 2011 | 12:19 am

I drove 3751s along with 4103s when I first started driving. I'd pick the 4103s every time. Column shift and non-existant A/C, along with the HEAVY steering, were the hallmark of the old "Dogs." Fun fact: Did you know that the roof panels and roof bows on the Silversides were THE SAME as what they used for the 4104? A 4104 is a 3751 without the frame, different siding, flat floor, air suspension and different end caps. You can use a Silversides roof panel on a 4104 and it'll fit exactly. The 4101-2-3 were derived from transit models. Some body and suspension parts on the 8' wide transits fit the 4101-2-3 perfectly, as well.

DeserTBoB | Oct 11, 2011 | 12:24 am

@Nick The "four on the tree" on the old Dogs was one of their worst features. If you can find a junk 4102-3, or a junk early transit with a stick, you can use the shift box and levers to convert. Grab the "stickless" steering column off the 4102-3 while you're at it, too. It will take a lot of "re-engineering" to get it done, but it's doable. Failing that, why not just have a machine shop custom turn a new bolt for you? As I say, the column shift on those stunk, but it'd be a lot cheaper to have a jobber shop turn a custom bolt for you than do the conversion.

Al Bianco | Oct 31, 2011 | 6:49 pm

Hey DesertBill--You have some good info about those coaches. My 4103 needs Driver Windshield and two rear windows. Any ideas from transit coaches?
You are right about the 4103. Some drivers said that it would run when newer coaches died,and when I compare the ride with all air susp coaches I've driven,it is smooother,by far.Also has gotten us ticket in New Mex desert at 80,and I had to change tire sizes to metric,and run engine at 2600. And it loves it,can shift fourth to third at 24-2600 RPM/56 MPH and runs at 2000 in 3 Rd.,up a hill. 5% grade and shift to 2nd.,at 38-42 MPH/2200 RPM.
Thought you'd get a kick out of this,as you could picture doing what I described yourself.
All the Best,Big Al,Mr Filter

DeserTBoB | Nov 01, 2011 | 8:24 pm

Testing...this site doesn't appear to be working too well. Hello?

DeserTBoB | Nov 01, 2011 | 8:32 pm

OK, now on to Al's question. Front and rear curved glass for 4102/3s DO NOT EXIST. That's a big reason the last line I drove for that had '03s dumped them...broken glass that was insanely hard to find, and EXPEN$IVE! The last time I found a 4102/3 windshield half was about 5 years ago, and it went for $1250. The rears are even worse...last one of those went for $1500, but it was NOS. 2600 RPM on a 6-71 is suicide, usually, and, unless you have a 4 valve head and N-series injectors and cam, they should be governed at 2150 no load. Running them higher than that might work for awhile, but engine life will be short. We used to run all our 6-71Ns at 2250, and the 6-71 two-valves at 2150. There's not much point in going faster, since HP starts to drop above 2100 anyway, unless you have a 4 valve head and bigger sleeve ports. A 4102/3/4 with the Trailways 3.875 rear will shift at 20, 30 and 50 MPH when governed at 2150. We had some with the "Texas" 3.56 rear end, and they'd shift at 24, 36 and 58, and would top out around 84. Most Hounds had the 4.10, which had a top speed around 65, which is why we avoided any used Greyhounds.

DeserTBoB | Nov 01, 2011 | 8:38 pm

Part Deux: We did have one early 1953 4104 that originally came from Greyhound, but they had the 3.875 rear. It was the first one they rebuilt as a 6-71N with N-65s, and it proved that the money for the N-series "kit" was well spent. Fuel economy went from 7.5 to 11 on the road. I have driven some 4104s with the Hydra-Shift 2 speed clutch, and they were able to pass any 4106 or MC-5 on a grade. Anyway, sorry about your broken's going to cost more than the bus is worth to replace unless you get VERY lucky.

DeserTBoB | Nov 02, 2011 | 10:51 am

ATTN: Al Bianco or any other 4102 - 4103 owners:
An NOS right side windshield glass has shown up on eBay today for $900. This will get bid up to probably a grand or more, but these are IMPOSSIBLE to get. If you're serious about glass replacement, bid now.

Al Bianco | Nov 02, 2011 | 1:54 pm

Hello DBob;
All your comments show the many experiences you still remember like still happening,and are great and correct. My coach has an N series with a Jake Brake,and 90 Mm injectors,and since I have done some latest technology additions ,I feel safe describing why I can run at 22-2500. Firstly,not running petroleum 40W lube,using Amsoil 100% Synthetic 15W40 with 1 micron By-pass filter; Have revitalized it with a molecular technology which imparts a Ceramic/metallic coating on all contact parts in the cylinder; running metric size ires allows 1/2 gear lower gearing to ease smoother ,later changes at higher RPM,of course. Third gear runs at 2000 at 58 MPH,which usually means pulling most hills in that gear ,which is about 1500 @ 48 MPH uphill. I drove Detroit 55 series(4 cyl-8 ltr.),at same speed with load on Grapevine many trips,in 4th of 5,at 1400 Rpm.
THought I'd update you on this old coach,and appreciate your kind input on it. Thnx,Al B

DeserTBoB | Nov 02, 2011 | 3:19 pm

@Al Bianco I hope you get that windshield...that is a GOOD price on an NOS piece like that! There are fiberglas replacements for the rear windows, but I forgot who made them. I know that my outfit sold off all their 4102/3s due to broken windows, and that was over 30 years ago. Holy moley, N-90s???? Yoikes, that's a lot of fuel! Sounds from your speeds that you have the 3.56:1 "Texas" rear end. Most of the Trailways 4103s I've come across that were from Texas had those, but most of the ex-Trailways 4104s had the 3.875. Greyhounds from the "second batch" after '56 all had 4.10s, which is why people complain that they're slugs. TMN&O, however, had a lot of '04s with the 3.56. 4.10 was the common suburban bus rear end with a stick, like the TDM-4515 I used to drive on a suburban route from Riverside to March AFB. That one was ex-LAMTA 2025, a 41 chair car. We had another 4515 bought new in '54 by Tanner when they owned the franchise, and it had the 3.875, odd for any transit bus. Anyway, sure hope you get that windshield!

DeserTBoB | Nov 02, 2011 | 4:01 pm

A Detroit 4-53 with a five speed sounds like a Flx Starliner. Did you drive for Tanner?

Al Bianco | Nov 02, 2011 | 4:50 pm

Hey D/Bob;
Actually was a 4 stroke 55 Series -4 banger in a MC 9 engine conversion. School paid $50,000 to put it in with all the electronics and aftercooling piping at the two side/top radiators. Had a 5 speed Allison 740Cr with 5th real close to 4th,making it easy to get a grip at about 1450 RPM,( 73 MPH Max),and like you said anything over 1600 was a waste in this engine as it produced 95% of torque at 1350-1400, and lost torque at about 1800.
Somebody posted an e-bay w/shield for pass side at $900,and I'd offer CASH $100. ,Driver's side,as there aren't many 4103's still running,and they know it. Some jerk might pay that because of scarcity,but there's a scarcity of runners (buyers)too.I'm an old peddler and am aware of some tricks out there.
The coach needs esthetics mostly,but as you know,it REALLY attracts attention everywhere I go with it.Has Alum wheels and not many leaks anymore.Remember that??
Regards, Big Al B

DeserTBoB | Nov 03, 2011 | 12:07 am

Wow...someone actually converted a 9 with a 55? That's...uh...crazy. I really don't think they'd take $100 for this...haha...NOS still in the box? True, not many on the road anymore, maybe ten, at most. Oh yes, Detroits were good at leaks, for sure, any of them, especially the old tin tops. Those old hoses on the old GMs were always a leak source, as was the trans, 50 wt all over the back of the bus, 4104s, too. Bad blower seals were always good for covering the back end in crud, too. Had one ex-Trailways that was so bad, the engine would partially run on the oil coming out of the blower. CHP finally red tagged that one until they rebuilt. That engine had over 600K on it when they finally tore it was BAD! The A/C engine was just as bad, 1 qt oil for a two hour run on a little Continental...haha! Sure do miss those old days, though...couldn't imagine pushing aorund a Van Drool or Prevost these days, or even a G4500. Not the aame.

Tim Hoskinson | Apr 22, 2012 | 10:04 am

To deserbob I can assure you that the roof panels on the 4151 and 3751 are not the same as the 4104. I own both and have done extensive work on the 3751 buses and know they are not the same. As far as the shifters are concerned anyone who thinks that the floor shifter used in the 4104 is somehow better than the column shifter in the silverside probably thinks that way because the only ones they have ever used were worn out and in need of repair. I have three silversides here that shift flawlessly and I like them far better that the floor shift in the 4104. The column shifters work smoothly and with little effort and they are also not in the way when you try to get out of the drivers seat. The column shift is simply like the rest of the bus if taken care of properly it works very well if not it will give you problems. Most of these buses simply have not been properly cared for over the period of time since being retired from Greyhound and are most often found in great disrepair. Tim Hoskinson

Al Bianco | Apr 23, 2012 | 12:11 pm

That certainly should be obvious to anyone involved with Coaches that were built to run hard and long. My 4103 only fails where the owners neglected it, as with most of the side windows young kids shot out with 22's.The coach runs and operates flawlessly,even with a lazy driver (25 yrs bus), shifts without clutch. The coach loves it when you care to shift properly,but will let you know when you don't. Is it possible that your side windows are the same as the 4103 ? Any ideas on side and rear glass availability? Keep up the good work on defending that design and model. There was one here in Fresno Ca. that even had a freezer that wpoud start the gen-set when you opened the lid. It sold easily three times that I know of,and I would have loved to own that column shift,and had to settle for the 4103 ,which is a close substitute. I went to 255R 80-22.5 to get lower ratio from 3:55 gears,and run 22-2300 RPM to catch 3rd gear at 58 MPG ;sets Tach at 2000,and that 6-71 ( 90 injectors)can climb 5% grade in that gear due to high RPMs in that gear.Use only Amsoil in all components and it starts -no ether- in winter (30-40 deg.)
Your work will keep those treasures always valuable,Congratulations.

Tim | Apr 24, 2012 | 6:16 am

Hi Al I am going by memory only but I believe the side windows on the 4103 have slight angle on the uprights at the dividing line. The PD3751 PD4151 buses have a 90 degree dividing line on the windows so they run strait vertical. There may be other differences that I am not aware of. I am only experienced in the PD3751 and PD4151 buses. I have done work on my 4104 but not as in depth as the 3751 4151 buses. Most often the windows in these old buses need to be removed disassembled and new glass installed. It is time consuming and most people will not tackle the job but it is the best way to make them look good as well as eliminate leaks. Feel free to e mail me with any questions you may have and I will be happy to help with anything I might have information on. Tim

Paul Cundiff | Apr 24, 2012 | 10:35 am

Hey Tim... where might I find side panels for the sliverside that I could experiment on removing dents from? Is there a classic buss junk dealer? Also just so I can get started on the dent removal process (in my head) were they aluminum or stainless steel. The bus I am to work on is on the west coast at the present time but once the code is cracked on dent repair we will get it here for repair.

Or better yet.. is anyone reproducting these panels?


Tim | Apr 24, 2012 | 11:07 am

Hi Paul it would rally be best to e mail me and I will get you my phone number as I am really not much for typing and the answers may get long. Tim

Al Bianco | Apr 24, 2012 | 11:13 am

Thanks ,Tim;
Possible then that the overall window dimension could be the same, but does the diagonal seperation on the 4103 make any difference to swap over?
Appreciate your interest and comittment to these treasures.
Regards, Al

Tim | Apr 24, 2012 | 11:30 am

Hi Al e mail me and I will get you the measurements of the windows. Tim

Hello bus lover
I have a 1959 pd 4104 in great shape
ready to go
It is all there except for gen set

$20.000 take it home

Thank you

Warren | Jul 18, 2012 | 4:26 pm

i am looking for a good running 40's pd-3751 or 4751.

Tim | Jul 18, 2012 | 6:14 pm

Warren there has been one on e bay its been on twice now. You could look there. I have some I would sell but they all would need the engines rebuilt as most really do even when they are advertised as ready to go. You will find very few PD3751 or 4151 buses in good road ready condition. The majority of them are not licensed and driven on a regular basis. Be very vigilant when looking to buy.If the bus has sat for some time be prepared to find many things in disrepair. Tim

Warren | Jul 18, 2012 | 9:15 pm

Thats what i have been finding, and the transportation costs to move it can be prohibitive unless it is close by, (even if I got it for free). I have found one close by that is in need of complete restoration, and that gives me the opportunity to make the engine upgrades i would like
(such as 4 valve head and turbo). I was maybe hoping to find one that would be roadable home, and then have a "moving project" so to speak, that I didn't have to dive into right away. But like you say, a guy has to be real careful with buses that sit too much. They were designed to be driven hard. BTW i am in So Arizona. Thanks, I'll check out ebay again.

Well I just purchased a 1948 silversides. I'm wondering if anyone has the original drivers seat, and some windows. I need (8) to replace where they removed for conversion. They also cut out the vent next to the drivers seat. Any close pics of original would be helpful to rebuild it back to original.

Tim | Oct 12, 2012 | 11:05 am

Hi Warren I have the parts you are looking for. Putting a bus back to even close to original after having been converted to a motorhome can be quite the job and very expensive. Really its always best to try and find a bus that has a light conversion and has not had the windows removed or modified. Let me know if I can be of assistance to you. Tim vifmw(at) the (at) of course replace with @

Hi Fred I have two PD4151 buses I would sell. Neither have a good conversion but you will find it difficult to find a 4151 as there were only 357 ever built with that model designation. Tim

Nice post and nice ride. I absolutely love these antique beauties. I have a 1954 GMC 671 Detroit diesel and it runs like a charm. I had an artist from Portland do the dogs for me. He did a great job. The interior is very nice but this spring I plan on doing some more inside work on it. I will post more pics as the progress is updated. These buses are so nice, water tight and dry in the rainy state of Oregon. Wish I had some kind of overhead cover for mine. Later :)

Hi Judy soda blast or plastic bead blast is the best way. Some use aircraft paint remover but it can come back to haunt you if it gets back under the rivet heads. Best of luck to you. Tim

I have a 1948 Greyhound bus that has been converted to a motorhome. I am in need of a VIN inspection but having a hard time finding it on this beast. :) Anyone know where it is located by chance?

David LaPee | Apr 20, 2015 | 8:04 am

If your title has a vin it will probably match the motor numbers if the motor is not oringinal the entry door has a plate usually that has the production number. other than that look in the spare tire compartment behind the front bumper. sorry I dont have any more info---see if the operators manual says where to find it or ask the highway patrol-- not a good way to go because they will ask you how you verified your title.
later Dave

Kyle Bushnell | Apr 20, 2015 | 9:02 am

Thanks for the advice. I will look around all those.

Tim | Apr 20, 2015 | 9:27 am

i haave a 1947 sillver sider with 654 detrot in it Iwould like to up date the drive trane is there a kit i could buy.

Tim | Jun 20, 2015 | 1:00 pm

Hi Philip never herd of a 654 detroit. I think you mean a 671 as the Silverside was equipped with a LA671 engine. There is no kit for engine swap in this bus and changing it to any other engine is quite involved. The engine in the siverside was L A 671 the L meaning left hand rotation. This means your engine rotates the opposite direction of a normal engine. I know of buses that were modified to except other drive lines but it quite expensive to do so. Tim

Kyle bushnell | Jun 20, 2015 | 2:27 pm

Just joining the party here...I just acquired a 1947 PD 3751 from another collector. It's original condition & still fully seated but some of them are rough. He had it 25+ years. It was actively driven up until 4 or 5 years ago. I'm having in hauled in later this week; figuring to clean the fuel system out and then looking forward to firing it up. Rumor has it that the original dogs are in storage nearby; hopefully that will come to pass. More when I know's nice to see such a vibrant community of collectors for these gems!
