Transmission end play

When I first got my 24,I removed the transmission inspection plate to check it out.
I found the hogshead was was completely worn out and purchased a good replacement.
I also found the drive plate had .070” end play.

The picture is with the drive plate pulled back and reverse drum pushed forward. Other picture is drive plate pushed forward.
Any idea what To look for as I pull it apart?

Be sure to install at least 2 bolts into the flywheel holding the main shaft tight to it. You may just be sliding the main shaft on the dowels, which would be the specified end play for the trans, but, .070 is alot.

Take the spring, then pressure plate off. Remove clutch plates, remove square-head bolt (side of clutch drum) and pull clutch disc drum off (it should be very tight and require a special puller) and you'll find 3 thrust washers. The thickness (wear) of those washers, PLUS the clearance between them and the clutch disc drum is pretty much the slop you're feeling. Usually a new set of 3 washers (or one new, 2 old, etc.) along with usual careful setting/pressing the clutch disc drum onto the shaft will solve the problem. There is a hole in the side of the shaft which the square-headed bolt goes into and it is fairly generous in size and allows for some up/down location of the clutch disc such that proper end float can be established. You're looking for something like .015" - .022" (or .015-.027 depending on source of info) end float when you're done. I shoot for 19-20 thou. and am done with it.

Taking the spring off the pressure plate is work that is not needed, 2 other ways to remove the plate are, back off the 3 finger screws then remove the plate or just evenly back off the bolts that hold the plate to remove.

Well, now that makes me feel a little silly...you're right. I never even thought about it that way quite frankly. Thanks for the tip!

We have always used .015, .010 is to tight, .020 is over kill, and you can start to here it clunk.

.070 thousandths, just make sure somebody hasn't mixed older, and newer parts. See how many washers it has first.

Always pull the clutch spring it's easy. We use a small O. T. C. press, and push the spring support down, and knock the spring support pin out, takes about 30 seconds, with a nap, in between.

Only use 1 bushing in the flywheel end, of the brake drum. The tail shaft should be line reamed, with the brake drum.

Thanks for the ideas. I will check the 3 spacers. All the bushings need replaced and I will have to check the drums. The triple gears look good at first glance. I already took the spring off and will proceed with the rest. Mike Bender's videos are a great help also.
