I put many miles on PD-4103s when I first started driving coaches. The 4103 was a big improvement over the Silversides in some ways, since it was quite a bit lighter and was an easy steerer. The A/C was marginal on the '03s, but somewhat better than the Silversides. Luggage space was inadequate for overnight charters, though. My favorite was an ex-Trailways around this same vintage. In fact, I think the serial number was very close to this one.

Hello Deser; Own a PD 4103 S,n 1462,which ran out of L A to Vegas,as I have been told. Sold in 60,s to Fresno Ca.) City Charter lines,and then to Joe P,of G&J freight.Joe,converted it to M/home and it was great job. Still looks great inside ,but has need of detailing. Most chrome still good. It is a runner. GM 6-71N,Has 90 Injectors,and 355 Rearend,and 80 MPH at 1900.Changed tire size to metric 275R70 and gained 1/2 gear on hills.I drove many MC9's and some 6&8 models for Community college in Fresno.Wish to sell to someone who won't need much but $$ to bring up to fun. Use all Amsoil in drive train,plus By-Pass filter,and starts like new all the time.
Good to talk to you. Regards, Al B

@Al, you are VERY lucky to find the 3.56 "Texas" rear end, although they did show up on a lot of the ex-Trailways '03s, as well as the TNM&O 4104s from 1956-7. Those with the 3.56 were real ticket getters on the flat, but dogs in the mountains. We did have one 4104, from 1957, that was delivered to LTR with the 3.56. It was the second fastest bus in the fleet. The fastest was a Crown tandem recliner we had with a NHH220 Cummins and a 12 speed air split Spicer. It would do 102 MPH at 2100 RPM. Although not as "refined" as the GMs, those Crowns were really great coaches.

ATTN: Al Bianco or any other 4102/3 owners: An NOS right side W/S 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. http://rover.ebay.com/rover/1/711-53200-19255-0/1?ff3=4&pub=5574634399&toolid=10001&campid=5336697092&customid=&mpre=http%3A%2F%2Fwww.ebay.com%2Fitm%2FGMC-Coach-PD-4103-Passenger-Side-Windshield-NOS-%2F160111754934%3Fpt%3DVintage_Car_Truck_Parts_Accessories%26vxp%3Dmtr%26hash%3Ditem2547677eb6%23ht_1110wt_907

I have a 1952 4103 Detroit 671, need some HV-6 injectors, mine is hitting on 3 cylinders, would like to drop 3 working injectors in and see what I have engine wise before I spend much money working on it.

Any help appreciated

When it cranks up on 3 cyls, do you get "white fog" coming out of the exhaust with it or no? If the bus has been sitting for years with fuel up on the top deck, they're probably plugged with algae. One way to tell is to pull a jumper and see how much crud is in it. Clean them all out (I used to use Brakleen, oddly enough), turque them back down after flushing the pump, and see what happens. If you are getting "fog" with the other 3 hitting, you may have some compression problems. Do you let it try to warm up a little like this?
