hi i just got done bolting my 644 to my 871 and the transmission is sitting off leval , at about 11 oclock, is this normal?????
Dunno. Is it rotated sidewise a little? You would think the tranny would set almost level in both planes, with a slight slope towards the rear axle. Is your Detroit mounted slightly tilted? Do you have some sort of unusual tranny oil pan? Others may know.
Allision designed the things to be mounted slightly off center. Forgot how much, but quite a bit is OK both side to side and front to rear. Your question is...is your application tilt normal? Dunno. What kind of Bus Conversion do you have? Is it stock or modified?
Reason I ask is we need more information. Maybe your coach has a tilted installation, or a repower was installed that way. The concern is that an off set mounting may affect your driveshaft angularity and alignment and U-joints and stuff. Alignment is important. :) :) :)

Are you talking the alignment of the engine/transmission assembly or a difference between the engine and transmission? I believe the engine/transmission assembly is angled slightly to the left so that the driveshaft will line up with the dropbox that is installed to the left of the rear axle center. There should not be any difference between the engine and transmission. Jack
no its not the angle in the cradle what it is the engine is leval,frt to back side to side, but the tranny pan is tilted to the left, also my coach is a 67 mci5a
looks like i will be taking the adapter plate off and redrilling holes, i know on a car or light truck application it has to be leval, so i dont want to talke a chance, so close i can see the engine running arggg!!!!
As soon as it gets light i will crawl under my 68 5A and see how my 644 sits. it will be another hour or two. :)
thanks, if you look under from the rear looking forward , my trany pan will be sitting uneven to the right,so all the fluid will be up against the side where the shifter rod is
WOW, I GUESS I SHOULD INVEST IN GLASSES, BACKED THE TRANNY BACK AND TURNED IT TO THE NEXT SET OF HOLES IN THE FLYWHEEL HOUSING , AND STAIGHT IT IS , SORRY FOR WAISTING EVERYBODY TIME, WITH ALL THE HURDLES I HAVE HAD SO FAR, I THOUGHT THE WORST INSTEAD OF THE EASY, THANKS AGAIN , BLIND KEN
I see from your post that you got it fixed. I just got out from under mine and yes, just to confirm it for you, mine sits perfectly flat/horizontal. Glad it was an easy fix for you. Wasn't a waste of time for me as i saw a couple of minor things that i need to attend to anyway. :)
Ed, I should bring a flash light to give you at Busn'USA next spring. They are a great little thing I'll show you how to use, so you can crawl under your bus in the dark and see... You would not have to wait for daylight. LOL. How have you and Stevie been? You should also think of coming to the BC Bus Nuts rally I'll be hosting in Invermere, BC on the May long week-end. Take care.

A flashlight? is that lightening bugs in a jar ? Hmmmm.......end of May for your rally? Last year i had to be at work on the 2nd of May. This year i did not start till the 9th of July.......only got in less than half the of the hours i worked last year. >:( We have already been back in Yuma for a week and a half......been a little warm the last few days here. :) Keep me posted on your rally, we would like to come if things work out. We are both fine, hope you guys are too....Ready for winter? ;D Ed
