4x4 swap

[Burck115]

So I have a 89 and it was originally a 2wd manual and I pulled all the 2wd stuff out and put 4x4 trans and all in but I used a transmission out of a 86 Cherokee and switched to the external slave cylinder. And I can't seem to get all the air out of the clutch line. I need help I have tried everything I know.

Unbolt the slave, hold it so the line leaves it as straight up as possible, and pump the piston up and down until you quit getting air bubbling up in the reservoir. 

What engine/trans do you have, and what clutch parts did you use? '86 could have had some funky stuff going on. Also, did you reuse your master cylinder? I don't know what the differences are, but there's parts number changes in between years and if you've done some recombining you may not have properly compatible parts.

Please explain your method of bleeding.

[Burck115]

Pumping the clutch pedal and holding it while my friend takes the bleeder loose. And then tightening it back up and repeating

[Burck115]

And we used clutch and slave cylinder from Rock Auto. Not exactly sure of the brand. But we are using the old master cylinder. But it was running and driving when we pulled it apart

I really don't understand what parts you used.

 

You're not bleeding it as per the manual though.

[DirtyComanche]

You can try this method though.

You should have an email with the part number you ordered. The brand matters less than what application it's for and whether or not it's compatible. 

I'm ASSuming you're looking at a 2.5/ax5 trans because you pulled it from an '86 and bolted it into an '89, but we're pretty clueless on that because AMC was using whatever parts they could afford to have on hand, which makes '86 a bit fuzzy. 

[Burck115]

We got the slave cylinder blead. But it's still not wanting to engage completely. So I guess we are going to pull the transmission back out. Anything we need to look for? 

[DirtyComanche]

How about you explain what engine, transmission, etc you have and where you got them from?

 

I'm guessing you have a 4cyl but I seriously don't know.

 

I'm guessing you have incompatible parts regarding your engine/trans choice and/or whatever you did with the external slave conversion.

[Burck115]

It's a 4 cylinder and we figured out that the clutch fork pivot ball clip wasn't on. Causing the throw out bearing not to engage like it should

I had a similar issue putting an 86 AX5 into my 87. I too ordered parts from rockauto. The 86 MC is different from 87 as the bolt pattern is different, and I installed the slave without the plastic cone on the end as I assumed the new one would come with a the new slave. I couldnt get full engagement because the slave wasnt pushing the arm in enough because it was too short without the nylon cone on the end. I finally figured it out and swapped the cone from the old one to the new one and all was good. That was several years ago, and now that slave cylinder is leaking!

What plastic cone are you referring to?

It goes on the end of the slave cylinder push rod to reduce noise and give the correct length to the pushrod. Its a white nylon plastic cone looking thing maybe 1 1/2" long and presses onto the push rod end.
