replacing throw out bearing

I will be attempting to replace my bearing and fork tomorrow by sliding the transmission back far enough to get my hands in there and do the job. Anybody pull this one off? I will take pictures and do a thread in the smaller projects section tomorrow after I am done. I already have the tunnel cover off and the seat box most of the way unbolted and ready to come out. Thanks to Justin for telling me how to get this done

I haven't done that but makes sense. The fork might be a pain to get off since you will not have much clearance but should be able to be done. There is also a little pin that holds the two together. It is plastic and might be gone. Some people do not worry about it on the re-install.

Have done it on several Series vehicles. Helps to have come-along or transmission jack. There was plenty of room to do everything including removing the flywheel for resurfacing. Don't skip the plastic staple.

I did it twice, I had more luck moving the engine forward and leaving the tranny in place, but I didn't take the tunnel off when I tried the tranny route.

Thanks for the advice. I think I am set as far as all the tools I need. One trick I did read about was replacing two of the studs on opposite sides with a longer stud to use to bring it back together easier I will post how it goes. On my way out to do the deed

So I pulled it off and will post some pics later. Before the thing wouldn't shift and was slipping a little bit. When I got it apart the bearing looked brand new and didn't show any signs of wear and the fork looked perfect also but I replaced both anyways. I got it most of the way back together, enough to test drive anyways. After some fiddling with the pedal adjustment the thing shifts perfectly but now is slipping in 2nd gear, like you can't drive it slipping. Could the contact point between the fork and the bearing be screwy and keep the bearing from retracting fully, therefore causing the slippage? Any insight would be helpful? I am at my wits end with this thing, I just want to be able to drive it. On a better note the removal and replacement of the trans was relatively easy with another person helping me. I did pull the seatbox and that was a huge help having it out of the way.

Thanks, Jason

Is there free play in the clutch peddle? If not, it will preload the clutch and cause it to slip.

It could just be worn out. Not sure why you did not change the clutch while it was apart.

from what I was reading I was under the impression if you treat it right and know how to drive a stick the clutch should last..I pulled a "Cheapfuck" I got everything back together and bled it but then had to adjust the pedal throw. Do you have to relieve the pressure and re bleed it? I backed off the adjustment to the point that I was having trouble shifting then tightened it up from there but I did that after I did the bleed. It feels like I have the right amount of play according to the book.

Do you know the history of the clutch?

There should be a little play at the pushrods.

No, I really pulled a cheapfuck by not replacing everything, I know. The good news is now I know how to do it so it will be a snap. The only thing that puzzled me was the way the bearing fit in the fork. It just didn't seem right

What do you mean? The fork has slipper pads that push on the recesses in the bearing housing. Nothing fits into anything and they are not attached. The staple has no purpose and should be removed.

Make sure you resurface the flywheel if doing the clutch.

I assume you put in mew slipper pads as well. If you really want the best, you can get an aluminum casing for the throwout bearing.

It just seemed like the bearing body didn't fit between the slipper pads, and no I re used the old ones. They didn't come with the stuff I bought. It really looked like everything in there was new, especially the bearing I pulled out of there and the clutch fingers looked new also. Should you sand that down so it fits between the pads, or should it fit in there all tight and awkward? I will get an aluminum body bearing since now I have to take it apart again. I thing I have the slipper pads in there wrong. I found the staple at the bottom of the bell housing and put it back on but I dont expect it to stay

It should all be snug. The slippers do wear and should be replaced. Did you reinforce the fork or use one that came reinforced? It is a good idea as they wear through. Some grease on the sliding bits can't hurt either.

The fork I got is pretty sturdy and yes i greased up the swivel points. Is seemed more than snug, it didn't seem to fit right. I will take it back apart tomorrow and see about getting the aluminum body bearing. I will have pulling the trans down to a science when this is all done.

Reviving an oldie

Should you grease the throw out bearing and the shaft it slides on?
That sounds terrible, but I need to do this tomorrow AM
Thanksgiving

I put a thin layer of moly engine assembly grease on the slippers, fork pivots and shaft
