Manual transmission installation tips?
Anyone have any tips for installing a manual transmission (Borg Warner)? I can't get the transmission any closer than 1.5cm from the bell housing. The shaft is in there, and it went through the throwout bearing and all that, but it won't go in further. I've been twisting and turning and lifting it for a good hour but I just can't seem to slide it in. What must one do?
Thanks :cheers:

Sounds like ur getting the tip of the shaft in but not the threaded groove parts lined up (insert dirty joke)... When I pulled my tranny, I had to rotate the tranny clock wise at about 3 oclock to completely remove it (it wouldnt let go pulling it strait out). Opp. when installing (start at 3, then go to 12). Good Luck.

Re: Manual transmission installation tips? (VetticusSupersonicus)
There are a couple of things you could check. If you pulled the clutch it's possible that the clutch disc isn't aligned properly. Get an alighnment tool and make sure everything is straight or the tranny won't go in. If that's OK check to make sure that the cavity behind the flywheel bushing isn't packed completely with grease. If it is the grease won't compress and the shaft won't go in all the way. This is a common way to remove the pilot bushing, packing the cavity with grease, then inserting a rod and hammering the rod until the force of the grease behind the bearing forces it out. You may inadvertantly be trying to do the same thing. One tip I can give you that might make it easier is to install some long bolts on the top of the bellhousing with the heads cut off. This gives you a set of guidepins that allows you to hang the tranny on while you guide it in. Once it's in install the lower bolts and then remove the two top studs and install the regular bolts. Hope some of this helps.

1.5CM?? IS THAT LIKE 1/2"?? if so do what I do (BUT DON`T TELL ANYONE) use the 4 mounting bolts, tighten them each carefully a little at a time and it will walk the trans into place. ...redvetracr

Seriously though, it does sound like the disc is out of alignment. The borg wennie is a 26 spline transmission and unlike a 10 slpined shaft the "twisting and turning" is probably unnessasary. I'm sure you got through the disc itself but if it's out of alignment you are probably not aligned properly to go that last 1/2" into the end of the crankshaft. With the pilot bushing in place ( it is there,right? :eek: ) it's a very close fit.
An alignment tool is a very useful piece for clutch installations. Your local parts store probably sells a universal tool for about $15.00 that can be used on many different clutches. No tool box is complete with out it.
Good luck.

Wonder if you could use studs? Would be a hell of a lot easier than trying to get your hand back there to start the bolts. Studs sound much better.

Re: Manual transmission installation tips? (VetticusSupersonicus)
Your pretty close...
Now have your helper go in and push on the clutch pedal, a little at a time.
You are allowing the clutch pad to shift a bit - now push the transmission!
There you go - done :hurray:
I was in the same place as you ST-10, couldn't get it the last 1/2 ".
Had the wife push a little bit on the clutch as I pushed. As soon as the
fork released a little pressure on the disc we were done...

Re: Manual transmission installation tips? (VetticusSupersonicus)
With the tranny out, the motor will lean forward. It will also rock when you try to install the trans, making it very difficult to install.
Get a jack and a piece of wood (2x4, 4x4, etc). You want to support the front of the motor - like under the front of the pan or crank pulley area. Lightly jack up the front of the motor until it begins to angle back & gets more secure. The eng fan may be getting close to touching the rad shroud & the dist may be touching the firewall slightly.
Once you have the motor at this attitude and it's not moving around anymore, it should be easier to install the trans.

That worked for me too. Push in the clutch and "POP" in goes the trans. YOu just a helper though.
Good luck,
JIM
