I set the END PLAY on first and second at 005 to 008 on most t-1's. Mendi's go up to around 014. Set the fixed third gear on the pinion shaft to a tight zero. there is no adjustment to the fourth fixed gear.

Agreed. I never understood why VW specified clearance under 3rd gear's circlip.
The current trans I'm working on came up with 1st gear endplay at .004" This meets VW's spec, but I increased it anyway. Set it to .007"

How is the investigation going for the correct torque specs for the 3 bolts while in the shift fork jig?

The Bentley and the Long Enterprise both said 18 ft-lb, a couple quick searches haven't proven out. Thanks for the reminder as I need to get back on that.

I did open another trans today, finally a really good reverse! people must hate reverse in these trans.

I don't have it infront of me, but Bentley lists the 1-2, and 3-4 8mm fork bolts at 18ft. lbs., but the 7mm bolt of the reverse lever I'm pretty sure is only 11ft. lbs.

if you have the solid spacer why do you need the 3rd gear clip? what is the thrust washer between the small pinion nut& the 1/2 clutch hub for? keep the nut from fretting loose? or am I not seeing something?do you shim up there to tighten the 3rd gear circlip?...or use thicker circlips? should I machine the spacer so the 4th gear sits on it a thou or 2 before the gear seats on the pinion?? me building many automatics, this termanoligy on all this stuff& exactly what it's called or where it is well it's kinda lost in my head at the moment, like a bag of marbles with a few lost&broken. (slight terminology/location issue.....& too much shit non related cluttering my head at the moment, I need to leave this thing alone for a while). and need to make an order from weddle at the same time.

Early trans have a nut on the end of the pinion and use a steel spacer, as do all Weddle pinions. If you use a steel spacer on a late shaft, all the thrust force is controlled by the 4th gear snapring. The shim you are refering to is used to set first gear end play.

Bruce, I found one manual that said 14 ftlbs for the shift fork bolts. It also has some neat homemade tools in it.

Well sure. Seasoned parts are better than new! Put it together exactly how it came apart and it will work great, but don't change anything!

It's just like cam and lifters. You don't mix em up.
And if halfway worn out, you can get new lifters and extend the life of the cam.

I really like everyone's comments.

Bruce, I see what you are talking about now. I will add the torque for reverse to the list.

Scott, thanks again for the end play and gear stack info.

Bruce/ Scott
What are your thoughts about a 10 tooth versus 9 tooth mainshaft for the street? Does the mainshaft only make a difference to drag racers, or do you want the 9 tooth shaft for hot street as well?

Also is a chromoly pinion nut worth it on the street? I think I remember reading they destroy the threads when taking them off or something, so some people didn't like them.

Scott,
You mentioned a different bearing to use when putting an old gear on the 002/113 mainshaft, I will do the 1.32 third in my late model gear box if I can.

Thanks
Tim

both the trans I tore appart have first gear thrusting agnist the pinion bearing race(big nut screw in bearing). and they both have sines of gaulding/wear there. SO is there an issue with me adding a shim there to reduce the contact speed if I account for the thickness of the shim? like machining the gear's thrust serface the same amount. and what thickness shim would be good? I have one that fits perfectly it's about .030 thick and hard(side gear shim out of a v8,s diff). and....what is the torquing procedure for the small pinion nut that tightens the pinion bearing?I seem to be brain dead or my bently manul isant cleare enough for the brain that are working.(Im used to crush sleves or shimming pinion bearing preload.)
