MC9 5-speed transmission removal

[phloide]

In order to fix a fairly serious oil leak, I have to pull the transmission , clutch and flywheel on my MC9 - 6V92 5-speed. My mechanic wants to confirm we can do it without taking the motor out. Looks like lots of room but not having worked on a coach before we want to know for sure. Also, any tips to avoid problems would be appreciated. Thanks!! ... Floyd Lillies, Nakusp, BC

Yes it's a lot of work, but it can be done. I changed a clutch on a 102A3 about 4-5 yrs ago! We did it from underneath and would do it that way again,  now with an automatic I'd pull both engine & trans! JMHO BK

It can be done. I've done a few.
Just make sure the bellhousing will be supported to frame (without the trans) before you begin.
In one of the MCI manuals it actually shows a dolly that rides on the rails, supports trans & slides unit away from the bellhousing.
Can't remember which manual, but I'll try to find some info if i can.
I used a big trans jack to support and remove the unit. Chained unit to jack for safety.
Never took it off of the jack, just rolled it out of the way.
Be careful - trans is heavy and clutch and pressure plate assy is very heavy too.
Mark the flywheel, bolt "ring", and put a mark on the bellhousing  before you remove the flywheel.Use a paint marker.
It will help during reassembly.
Best of luck with your repair.

Floyd, good luck on your job. Please, if you don't mind, would you advise me what size (diameter) clutch you have in your MC9 and whether or not it is a twin Disk clutch?  If you read my post earlier and my request for MC9 Clutch information you'll realzie why I'm asking.  My Email is in my profile.

Thanks,

If you have a forklift to pull the motor, I think it's way quicker to pull the motor & tranny, than laying on you back with dirt and grease falling in your face .. it only takes me 4 hrs to pull it. and way easier to work on.
