1952 GM PD-4103 ex-Greyhound - Frozen in time

I just purchased (summer 2012) a General Motors Coach PD-4103 yesterday off a farm in North East PA. It was sitting in the same spot since the 1960s when it was taken out of service with Greyhound. It is all original and hasn't been touched since parked. It was like time froze around it.

It is a 1952 PD-4103, Serial #725. All glass is good besides a few side windows. Both aluminum bumpers are straight too. Arrow turn signal lenses are good and even the reading lamps inside work when I took a battery to it. Heater fans kicked on too! Didn't try to fire it up yet, but the engine does turn over freely.

Would love to hear from anyone who is familiar with this vintage bus as far as restoration and mechanical matters...

Thank you for the interest,
Kevin Lewis

I really hope to get some more information on this bus. It would be greatly appreaciated. I do not know much about buses. Just found this bus on a farm and bought it on a spur of the moment type deal. | Sep 19, 2012 | 8:13 pm

Kevin, thanks again for submitting the above photos to Looks like you'll have your hands full restoring her, but should prove worthy.

You inspired me to dig up some photos I took back in 1997 of a beautifully restored GM PD-4103 similar to yours. I just posted them here on the site:
Hopefully it can serve as a template for you. All the best.

We have a 1951 PD4103 #057 that we are currently converting to a motorhome. What are your plans with yours?

Kevi Lewis | Oct 11, 2012 | 5:18 pm

I really dont have any plans yet. Because it is all original with all seats intact I would probably like to see it stay original. It even still has the original greyhound van lines medical kit in it!

Mary Heiser | Oct 11, 2012 | 6:43 pm

We would love to see some pictures of the inside with the seats and luggage rack if you have them. If things change we are in need of parts and would be interested in buying it or just parts. We especially need the front windshields - ours are cracked. I inherited the bus from my brother who passed away in Feb. 2012 (he was a Vietnam Vet and is was buried in Arlington)- he had owned it for 16 years and worked on it a little at a time until he got sick. His dream was to travel and live in it. We couldn't bare to scrap it and since we do a lot of RVing ourselves and own a 88 Motorhome we plan to use parts for the Bus, we decided to continue with his dream and finish it. It had actually been sitting and had not been started for about 3 years (in North Carolina). My husband and a friend drove up to North Carolina in April and was able to drive it back to Florida (where we live) with no issues. We did put brand new tires on it though before they left North Carolina. There are not many of these buses around - there was only 1501 made and our number is 57. My email address is if you want to send the pictures and I can send some of mine to you too.

yes i heard the windshields for this model are very hard to find. Luckily both of mine are intact. I sent you over an email earlier this afternoon with pictures of the interior which is in very good shape. I haven't really considered selling it but again i dont really have plans for it either so I would like to see it go to a good home.

Hello Kevin and Mary;
Guess what? I own S/n #1461,which was converted in 1980 by a Calif. Trucker,who did a real good job,to make it function for day and night use. Seats up to 14 and sleeps 5,due to convertible beds in front and rear bedroom. Remains in it's tradition as the most reliable model GM built,it would be the one to go to when all others would not start or run. Has original 6-71 with 90mm Injectors and By-Pass oil filter ,and used to run at over 90 MPH in calif,L.A. to Vegas,before City of Fresno put in Charter fleet. Now runs with much power ,since I installed smaller Metric tires (255 ,and 235 front),which I recommend,as rear end gears are too tall.(High-355:1)
All Amsoil lubes allows very LONG service intervals,and EASY winter starts. Have same drivers windshield problem,(neighbor?? put rock thru it after $700 replacement 2 weeks prior.)
I will try to send pics,but the ONLY issue it has is Esthetics__New Paint,and some rear glass,which I knocked out one day.
Wish you the best,as you will stop traffic on the road all the time. Everyone,young and old,will stare at it.And that is a problem with these coaches-They take over your emotions,and become a part of you. Possibly why you bought # 725,which by the way has the same pass. side mirror as mine,some did not,like # 72 ,like Mary's
Suggest you get with an Amsoil dealer or me on pre-start lubing for your engine Kevin,or maybe you have already done that. Those engines love a 15W40 lube in Synthetic,as old 40 wt.petroleum takes more energy to start and maintain oil pressure,get it in Gear boxes for sure, since sat so long.Do not worry about leaks,as bad seals leak regardless of lube,but best lube never fails to protect.
Attempting to assist in areas,you might not have info on,so pardon any sense of pitching product.I really wish to help,in areas,some maintenance people may not have latest tech knowledge,and that is what I do all the time, Vehicle Maintenance Technologies.Including Hydrogen on Demand fueling ,with your diesel to clean exhaust and reduce fuel consumption dramatically.Soon on my rig.Best regards, Big Al B.559.281.4804

Mary Heiser | May 08, 2013 | 2:57 pm

Al,thanks for your comments. You right we do get the looks!! We nearing the end of our conversion - hopefully have the interior done enough so we can start camping in it. Sorry to hear you got a rock through your windhields but curious to know where you had them made? My direct email is

Kevi Lewis | May 09, 2013 | 5:52 pm

Al, my email is

Al Bianco | May 10, 2013 | 12:03 am

Thanks Kevin; Small world indeed. Is That you on Right or on left in Pic.I think it is guy on right,that I talked to.
Will send quick note soon. Thanks, Big Al B

I also have a 1952 GM 4103 #1184. I drove a few times and on the way to Biloxi it broke down (overheated a bit) but I got it back to Philly. haven't done much with it lately but I would like to.

Mary Heiser | Jun 01, 2013 | 8:50 pm

Hi Lou,

Do you have the original windshields or have you replaced them?

Lou Lupo | Jun 02, 2013 | 2:23 am

I have the original windshields (I hope?) I have not even seen bus in a few years. I keep it stored in NJ and it was a good location since it was a bus repair facility (US Coach) but they have moved so now its just a school bus yard. I'd better go check it out and move to closer to home. I will take some pics ASAP.

Mary Heiser | Jun 02, 2013 | 5:56 am

We know US Coach - we have ordered parts from them. Our windshields are cracked and we will need to eventually replace them - either from another PD4103 or eventually find someone to make them. It's been difficult because for someone to make a mould, it would be costly. If there was a handful of other people who needed windshields it would cut down on the cost and the mould charge could be split among all of us.
