I am replacing all the seals on my transmission and was wondering what the torque spec is for both the side cover plate and the drive flange bolts.

How about the seal inside the speedo drive gear? I have a new one but I can't figure out how to replace it. Seems like you almost have to split the casing to get it out.

I got it open but the seal sets way down inside the aluminum casting. No visible seams where it might come apart. Oh and anyone can chime in with those torque values so I can put this thing back together. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Okay I found the drive flange torque value 25-29. I'm concerned about those 13mm nuts for the side plate. I would hate to strip one.

Some people say synthetics are too slippery for the 901 synchros. Having said that Ive used Mobil1 in my tranny before, with no ill effects..

I have some excess Swepco laying around , so thats what I use now.

The torque on the 8mm studs is like 18ft/lbs I think? I have to look it up, and the manuals are at the shop

18 seems high. I was thinkink along the lines of the engine case torque of about 14 or so. Boy I could use this info. It's gonna get dark.

Outstanding!!!!!!!!! This will get me there although a damaged one of the side shaft seals so I'm stuck on the left side. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) I'll bet my FLAPS wont have it either.

Well I have to stop for the day but I managed to get the rt. side cover plate o-ring in as well as the rt. side seal, the speedo drive o-ring (although I had to find a suitable substitute out of the shop) and the shift shaft seal. That thing was too easy. I'm almost afraid it's wrong because it went together so well. Oh well, will find out when all my gear oil ends up on somebodies driveway.

I am watching this because I will be tearing down mine hopefully next week to fix it being stuck in two gears. Not so sure about it. Downloaded redbeard's trans info and have my factory manual. It may take a thread w/ alot of questions to understand it all.

If you take your time and go easy, you can do each side in 20 mins.
