w56c w56d hybrid
« on: Jan 27, 2018, 06:19:26 PM »
Hi to everybody on here! I have a few questions and I was wondering if anyone can help me.
I have a w56C transmission still in my truck that has bad gears and I have bought a w56D with good internals but has some badly cracked and beat up front and rear housing.
I am planning to combine the w56D internals and center plate with the W56C front and rear housings and bellhousing and I have a few concerns that I would like to clarify before I rip the transmission out of the truck.
My concerns are:
- Clutch: I know that w56D were equipped with a slightly larger clutch and flywheel. I was wondering what are the differences between the 2 trannies to adapt to a different clutch? all I can think of is a different bellhousing... would I be able to keep my w56C clutch, flywheel, clutch fork and thrust bearing if I keep the w56C bellhousing or is there any other differences?
- Front main bearing: I know that w56D were equipped with a slightly wider input bearing (but with same OD and ID i believe) so do they have a different front housing or is the difference in the bearing retainer cover? Can I use the upgraded w56D bearing if I also use the w56D bearing retainer cover with the w56C Housing? Or do I need to downgrade to a w56C bearing to adapt to the housing?
- Other bearings: are any other bearings different between the 2 trannies or is it just the input bearing?
Thank you in advance for any help!!

ok so clutch... you can run either clutch in either bellhousing, just have the matching flywheel.  I suggest running the 9 5/16 (later) over the 8 7/8 (earlier) just because of surface area for the the clutch to grab.  Front main bearing... Some W56-D have a wider bearing and some do not.  Either way you can use the nose cone off your w56-D and you will be set with the bearing.  Other bearings... The rear output shaft bearing is different.  You need to use the bearing off the W56-C if you are using the w56-c rear housing.

I was looking at the part numbers for the input shaft bearings on Marlin's website, and I was wondering why there are 2 different part numbers listed for each trans?
w56C 6307N - HR6307N
w56D 35TM11UR - 35TM11NX1
Thanks
