low rev race to high problem

Bear with me fellas its hard to satisfy the beeds of this forum to put everything in the title line. Title lines only allow so much. OK here goes. Issue is that although my intermediate clutch pak height comes EXACTLY to the same height it did before disassembly so thats all good for clearance from there to pump my low reverse inner race is up aprox .100 to high stopping my pump from seating. Had er apart three times. What could hold the centre race high while clutch pak comes to PERFECT height?

PS. although I doubt it,is it supposed to pull into place?

Scrap that. From reading I know its not supposed to. Like I said though I just dont get how every height comes to exactly where its supposed to except this final inner race. Every wear point, every snap ring (Inner and outer) EVERYTHING. So its not a tear down. Its some how in how this inner race is sitting I just cant figure out what

What books do you have? I thought you mentioned having books?

The books I have seen indicate ways to check this stuff.

It is very difficult to explain so items on the internet forum

sessions and B&M (for what the latters worth)

And sessions does, but heres the thing. I've had it torn back down to sun gear base and built back up again to where my intermediate pressure plate sits right at the bottom of the notch in the case for it. You CAN'T go lower than that with the components, yet still that inner race is to high.

hmmmm, the Sessions book should indicate that the race in the center support engages onto the planetary unit...

if the race is not properly engaged , the race sits high and nothing is correct above it.

Yes make sure the low inner race is engagede into the rear planetary lugs.

It's also easy to not get the forward clutches all the way engaged onto the input ring gear.

Have any of the parts changed? Input shaft/drum, pump, etc?

Worlds most minute,like .0005 burr on sun gear. That solved my final end play is .041-.042. I know thats within the .045, but do I let go or not? What are the cons of comming that close to the upper limit? PRETTY CLOSE TO WHAT IT STARTED AT. It started round .046 and was living

If you have a GM 10 or 12 bolt pinion shim, they are usually around .030" thick. You can put it under the thrust washer on top of the forward planet and it will tighten up front endplay without moving the drums away from the pump.

You can also use a shim between the pump stator thrust washer and the pump.

And needed in this case? God I hate the ripping that goes into pulling that pump off. I know I'll be smooching atleast a gasket bye bye

I would but that's me

Removing the pump is easy. Use a small prybar between the int. pressure plate and direct drum. Pop the pump up and out.
You should be using assembly lube on the pump o-ring.

I got so much *** lube on that Oring and every where it aint funny. I get the impression I got a tighty.6 foot johnson bar and no less to break me fit. I aint kiddin. Anyhoo,apart,front washer shim made and installed and a .017" end play. Can I get an AMEN?

Its funny the inventions you do on or about your tenth disassembly. I cut two pieces of 5/16 threaded rod about 5/8 long, cut a slot to screw them in the holes under the 3/8 threaded holes in pump, greased a couple 5/16 ball bearings to go on top. Put 3/8 bolts in those holes and jacked the pump up like nuttin
