240 what's wrong with my m46 clutch?

[digital.aaron]

So a couple weeks ago, I did a b21 -> b23 swap. I pulled the tranny with the b21 and then moved the tranny, clutch, pp, and flywheel to the b23 and dropped it all in. While connecting my clutch cable to the fork, I notices the fork had no resistance against the clutch cable. The fork moved easily back and forth. Not knowing the problem, I pulled the engine again tonight and took the tranny off. I don't see the problem. I don't have the return spring but have been told I don't need it. Tranny worked fine on the b21. Anybody have any ideas what's up?

Here are pics of the suspects.

Did you try adjusting the clutch cable up till there was 1/8" of slack?

The problem with that is that the slack doesn't pull up until the fork is already in the fully engaged position. It's like there's no pressure from the pressure plate resisting the pull of the cable.

Clutch plate in correctly?

I think we need a more thorough description of the problem. Do you mean that the fork moves forward and hits the bell housing before The release brg contacts the pressure plate?

Should the clutch to pressure plate orientation be like this:

Or this:

 

[Harry Tuttle]

The second one. If you put the plate in the flywheel backwards, the hub/spring unit, which protrudes more on one side, will bind. The protruding side must face the pp.

 

[digital.aaron]

Yeah, that's what I thought. That's how it was mounted. And it didn't feel like the ToB was pushing on the PP. Someone on Facebook mentioned I may not have the spacer behind the fly wheel. Seems to make sense.

Could this be an issue?

B23 rear main

B21 rear main

The b21 doesn't have the spacer part. Maybe the one on the b23 is prevent in the input shaft from fully mating...

The spacer is only used with an automatic trans flex plate. That is what the problem is. Also, you don't have the torque converter pilot bushing still in the back of the crank of the B23 do you? If I'm understanding what you are saying, the pilot bearing and retainer snap ring show in the pic of the B21 are what should be in the B23 crank. Not that long steel bushing that is sticking out of the crank.

 

[digital.aaron]

What's the best way to remove the spacer if it's stuck good and tight?

 

[digital.aaron]

OK, I removed the spacer. Here's how the whole thing looks right as the bearing hits the pp.

It looks like this should work better.

OK. Now, did you install a pilot bearing in the back of the B23 crank? IPD sells them if you don't already have one for it.
