We Have a 1955(according to the title)General Moters Coach, it appears to have been converted from manual trans to an automatic.Is there anyone who can tell us about the bus's history,help identify the engine, and tell me where to look for tags or stampings to help identify the transmission(I am assuming its an allison),differential,and the devise between the engine & transmission that directs the power at an angle toward the differential(I really need a term here). The bus #'s PD4104-1399,#'s stamped on engine block 6A367024, 1067-8503 I also would like to find books on this machine,OP Manual, Repair Manual, Parts Manual Thank's Rke | ||

Kent - To add to what Mark posted: The differential is a Timken unit, which has been absorbed into Rockwell/Meritor. The angle stuff is known as a "bevel gearset". To better ID the transmission: If it's got a big, bowl-shape to it just inside the chassis side access door, it's probably a V-730. If the big round end is flat-bottomed, it's probably a VS unit. Either way, there should be a stamped ID plate on the side of the gearbox. Also, if you call your local Detroit dealer with the engine and transmission ID number, they can tell you exactly what it is, and what they have in their records as to how it was originally configured. Lots of busnuts use ramps to get under the coach - just build them sturdy enough to support 15 tons!! Also, build them long enough so you've got more of a gentle slope to climb, with a plenty of room on top for the wheel. Some kind of "stops" at the end to keep from running off is a good idea, too. Welcome to the madness! HTH. . . | ||

i use a pair of railroad ties beveled at one end so i can just drive up on 'em. they are *heavy*, but they get the job done. i didn't have 'em with me on my trip to lukes (us coach in berlin, nj). i was on my way back, and wasn't going to make it all the way back to seattle without putting gear oil in the rear end. ended up at the seediest truck stop i have *ever* seen... had to add gear oil to a leaking rear end (seals) on the way back... this is when i had the dubious pleasure of airing up the bus, sliding under it, having a friend hand me a couple of gallons of gear oil down the alternator access hatch, fighting about a gallon into the rear end, then having to have my lady start the bus to air it up enough so i could get back out from under it. :/ i've got a scenicruiser, so there's plenty of room for *me* under it when the bags are flat, but getting in and out is a serious lesson in gymnastics with no air. the entire time i was very aware of where i could and couldn't be, but frankly, a set of ramps would have been much much better. :/ -dd | ||

dd, My cruiser came with steel tubes to put under the suspension bumpers to keep the bus up while working on it (even if a bag blows out). They are ~1/4" wall & the ID clears the rubber bumper. I have also used wood blocks (& I have seen some get crushed too, so I like the steel tube better). Ramps are fine, just be sure they are sturdy & on solid ground. Amazing how easy it is for a bus to mash something into the ground, BTDT. Solid lumber with small/ no knots is best. | ||

Thanks Bob, I never was that big an Elvis fan, and I am in no hurry for that concert. Mark, The web pages are very informative THank's RJ, the old girl has a big round end with no flat spot. This bus thing gets more interesting all the time. By-the-way, am looking for reputable bus repair buisness, or mechanic. And someone who works on the RV, or conversion portion of the bus. Thank's Much Kent | ||

Many years ago, RJ told me that my 4104-1559 went to Scenic Hiway Tours in California. That made sense since I could see the name under the paint on the side. The list posted above http://www.geocities.com/buslist/Delivery/PD4104/pd4104_5.html shows it going to Modern Coach Corp in Georgia. Any idea why the confusion? Len | ||

New Mexico Transportation Co The home office for New Mexico Transportation Company was Roswell,NM. New Mex.had a lot of GMC in their fleet over the years 4103,4104,4106 and 4107's. They were part owned by Greyhound at one time that is why you would see the New Mex equipment with Greyhound dogs on the side of their coaches. TNM&O bought New Mex and it was merged into their system. I do not know the date of the buy out but it was after New Mex had the later MCI's in their fleet. jlv | ||

I looked at the buslist site and cannot find my 1960 4104 bus. The serial number of my bus is PDY1044971. Where else might they have a list of busses and their history? . | ||

Austin, You could go to the MAK board and see if JL Vickers (Roadrunnertex) can give you a history of your coach. | ||

Thanks everyone... I'm just outside Memphis TN, so Jonesboro AR makes sense. Is there anyway to track where it went through its life? I am the recent co-owner, only 6 weeks. It was owned by a Gospel Group for 20+ years prior to us. And very well taken care of. Prior to that I don't know. . | ||
