G52 Transmission Input Shaft Play Tolerance
« on: Apr 20, 2020, 05:55:21 PM »
I am replacing my clutch in my 1984 truck (trail truck locked front & rear), and with my G52 transmission out, I noticed the input shaft has about 0.04 inches of radial play 9side to side or up & down). Fwd and aft is pretty good. Is this too much play? If so, can the bearing be replaced without taking apart the entire transmission? If not, can I just switch my dual case setup and I think my 2nd case was out of a 1983 onto a W56 assuming I can find one?  Or is there a better option?
Thanks in advance for any help.

The transmission input shaft should really have no play at all. When I swapped an R150F into my '99 4Runner, my input shaft had ~1mm (0.04in) of lateral play (up/down/left/right) and ~1 of torsional play (clockwise/counterclockwise), but no play in/out.

Here is a video (turn sound all the way up)

I did a little more research on the transmission and found the vin of the vehicle it came off of, and discovered the vehicle had well over 300,000 miles on it. I decided to have the transmission rebuilt, when it came back, there was no play in the input shaft, everything felt tight.

I can't answer your other questions since I sent mine out to be rebuilt. Good luck!

Any recommendations on where to buy new input shaft (as my had worn away on end with pilot bearing not sure how I missed that) and rebuild kit as took the tranny apart a bit and input bearing is not 100% (as previous response was correct), but Marlin does not have any right now nor did Toyota? Any one ever use any of the Cobra Transmission kits? Tried to find a replacement G52 or W56 locally and could not yet either yet.

It should be possible to fix the nipple that goes into the pilot bearing.
