Question: Can a Spicer 7145 VE transmission (from a 4905) work in a 4106? Here's what happened: First of two senarios...either my 4106 came with a 4905 transmission which is unlikely in my opinion...after reading about all the trouble busnuts have had with shifting their dry clutch transmissions from neutral to first with the engine running. I didn't have that problem shifting with the transmission that came with the bus. Senario #2: The detroit dealer that swapped out my transmission instead stuck me with the one they found at a repair facility in Wisconsin..which by appearance had more wearing of the shafts. The original reason for the swap, I'm thinking, was that the Detroit dealer was trying to convince me to have an automatic installed, but I wanted a 4 speed and found a rebuilt in Oregon, purchased it and had it shipped to the DD shop. If my suspicions of Senario #2 prove to be true I'll be lodging a complaint with Detroit Diesel in Michigan, against the DD dealer that swapped out my transmission. (more to follow) | ||

Here's the more: My main problem is my vision which keeps me from seeing exactly what I brought home from the detroit shop 4 years ago and have in the garage under black plastic. When my wife and I uncovered it, 2 days ago to inspect the model#, she found it to not be a 7145-VC which is for a 4106, the label stated it was a 7145-VE. The latter I'm told by US Coach is for a 4905. Which brings me back to the question, "Will a Spicer 7145 VE work in a 4106?" Thanks...Lord Bless. | ||

the 7145vk/8v71 combo will work/fit in a 4104.... iv'e got 1 to prove it.... gear shift and clutch linkage looks kinda home-made... but it works/fits....and has several thousand miles on it... don't have any history on whomever did the install... kinda black-smithy in appearance.... | ||

Kenny, I'd tell you if I could. All I can say is that the oil bath clutch will required a sealed bell housing, which is not the case in a 4106. I would call Luke to find out what it takes to use it in a 4106. Good luck. Tom Caffrey PD4106-2576 Suncatcher | ||

Had a nice chat with Kenny on the phone the other day. All he's got is the somewhat-square transmission sitting in his garage. This unit does not have the angle drive adapter nor the tailshaft adapter on it, it's just the gearbox portion. FWIW, RJ PD4106-2784 Fresno CA (Just down Hiway 99 a bit from Kenny) | ||

Hi, RJ. That clears up a lot! No wonder he was wondering about it. Thanks. Tom Caffrey PD4106-2576 | ||

Dear Tom; RJ stopped by to look at the transmission and for the first time we uncovered more of it than just the Model # and guess what we found? It included the bell housing, the bevel gears, the tailshaft and the gearbox. Seems like having the transmission out of mind and out sight for 44 mos. and 2 seizures did nothing for my memory. RJ said that he was going to post exactly what he found. Lord Bless You, Kenny Cole | ||

Tom, Brian in OR, JimMC9, Luke, et.al: As Kenny mentioned, I stopped in to see him, Jackie, and his transmission Sunday moring. In addition to what Ken said, here's what I found: He has the complete V-drive manual gearbox assembly out of a 4106-4905 GMC highway coach, less the clutch parts. This includes the bell housing, angle drive, gearbox and tailshaft with drive yoke. So I stand corrected regarding my previous post - sorry about that, guys!  As for condition, the bevel gears are toast. The clutch-side bevel gear (which was laying on the floor separated from the rest) had one badly broken tooth that I noticed immediately, and other teeth were showing effects of the broken tooth's demise. The transmission side bevel was in better condition, but still had markings on the teeth from where the broken tooth on the other gear had interacted. The cover was off the top of the transmission, and a close inspection showed signs of wear on the shifting forks, but nothing unusual, considering it's age and how many hundreds of thousands of miles it's accumulated. The exterior levers seemed to be in a similar condition. By sliding the shift collars to the neutral position, I was able to rotate the gearset inside the transmission. All the gears seemed to be fine, no noticable or unusual markings, chipped teeth, etc. The shift collars slid easily, so they appeared OK also. (See, even with all those drivers over the years "grinding gears", they still hold up! Good old GMC!)  The tailshaft and drive yoke appeared to be in normal condition for it's age, with no apparent "egging out" of the yoke. Without further tearing down and inspection, it appears that the gearbox itself is fine, but the bevel gears are history and would have to be replaced. I'm not sure how much of a job that is, perhaps Luke could jump in and share. It was nice to visit with Kenny & Jackie, and to see that his spirits are still high, considering the medical problems he's having. HTH, RJ PD4106-2784 Fresno CA | ||

RJ, I guess that makes it a dry clutch, then. I didn't know that the 4905 could be either wet or dry. Learn something new every day. Thanks, RJ. Take care, Kenny and Jackie. Tom Caffrey PD4106-2576 Suncatcher | ||

Tom - Me thinks me put me foot in me mouth again. Maybe. . . It's been so long since I've looked at a wet-clutch V-drive, I've forgotten what's different about them. Since there were absolutely NO clutch parts in the bell housing, I can't confirm if it was a wet or dry clutch in it's previous life. Since Ken's got a 4106, it most likely is a dry-clutch model, but then again. . . Will post a new thread with this question directed at Luke for clarification. Sorry for the confusion. . . RJ | ||

RJ, don't lose any sleep over it. I'll just watch for anything I see that tells me, one way or the other. My main reason for wanting to know is curiosity. Take care. Tom Caffrey PD4106-2576 Suncatcher |
