Hey guys, just swapped out my 700R4 for a t-5. Got everything in today and when we cranked it up, the wheels spun a little. After testing, we figured out that when you crank it up, it wont let you go into any gear other than sometimes you can go in 1st. Its like it wont disengage. Try and put it in reverse and it grinds. Now, you can cut the car off and put it in a gear and it'll crank and be in that gear. We think it's either the slave silinoid or the pressure plate. Which the pressure plate bolts up to a one piece rear main and pressure plate, while the tranny was orginally on a two piece main with its own pressure plate. (dont know if it matters). We then put the original plate back on and it does the same thing. So, any advice would be great. Thanks.

 

Pilot bearing?

 

Which of these 2 ways did you put the fork into the throwout bearing?

 

from what I can tell, it was the second waywhere the spinning side is on the pressure plate.

 

Not that, it's the same in both pics....

Look at the 2 little ears of metal that are part of that little spring thing that's riveted to the fork. In the first pic they're on the outside of the groove in the throwout bearing; in the second, they're inside it.

 

ok, well, then it is definatley the second one with the metal teeth on up the release bearing

 

Well, if the metal teeth are up on top of the throwout bearing, outside the groove, then that's your problem. They're supposed to be like the lower pic, where they're inside the throwout bearing groove.

If they're outside the groove, they will hold the throwout bearing away from the fork by about 1/8", which translates to near ½" of slave cylinder travel. This will force the clutch to adjust itself to that point, and what you end up with in effect, is only about ¼" of slave cylinder travel that's actually doing useful work. The first half or more of the clutch pedal's motion is doing nothing except taking up the slack from that little spring.

OBTW how's your extension housing?

 

extension housing?

 

hey, and you meant its supposed to be like the FIRST pic where they are inside the groove, right?

 

ok, nm, I saw how you meant in the 2nd pic, but I still have the 1/2 inch of slack that your talking about, even though its in there right, why would it do this, is there some type of adjustment I can do?

 

extension housing = the object I shipped you

No, the upper pic is the wrong way, where the spring is outside the throwout groove.

 

Oh, I didnt realize you were the one that sent it to me, acutally I didnt even use it because I didnt know you could just chnage out the vss. Did you see my last post though, I actually did put the trough-out bearing in correctly, yet it still has that type of slack. Is there some type of adjustment to make?

 

There's no adjustment.

Pressure plate is the same for either style of flywheel (crank flange).

About all that's left is the pilot bearing / bushing like was mentioned above, or something wrong with the hydraulics, or the clutch itself. Since it works with another clutch, that pretty much rules out the other possibilities at this point, unless there's some other assembly problem.

Did you put a pilot bearing or a bushing into the crank?

 

How does the pedal feel? Are you using a new clutch master and slave cylinder? If not, you might have to do what I did and flush the system with fresh brake fluid. My car sat for so long with the previous owner that I believe the fluid collected water and was boiling when the engine got hot. This caused the pedal to get really spongy. But in your case you might just have air in the system. Flush the system and see what happens.

 

I tell you what, my pilot bushing doesnt look anything like what I've been seeing, mine looks like basically a gold colored cylinder that is plain inside, where-as from what I've been seeing, the pilot bushing looks like it has grooves and stuff inside it. Could this be the problem

 

Maybe. Does it spin easy on the input shaft?

 

it doesnt spin

 

We are referring to the Pilot Bushing correct?

If it doesnt spin on the shaft, it better fit really loose in the end of the crank. If not, you found your problem.

 

Sounds like you have a bushing, rather than a bearing. The thing in my pic is a roller bearing. The bushing is just like that, the same size and all, except.... it's a bushing instead of a bearing. Still, that's fine, not a problem; mostly I was making sure you had one in there.

Did you load it up with grease? If you did, then it will be OK and won't tear up, and over a short period of time, it will wear to fit the input shaft.
