internal clutch slave pin?

My son is currently working on replacement of a clutch master and slave on a 1989 ax15. I have not been able to help do to an injury, and he is saying he cant get slave out after dropping transmission because a pin wont come out. The book makes it sound like a roll pin but that same book didnt tell us about the 2 E-TORX bolts on bellhousing either. My son says the pin looks like a allen wrench would go in it, but it wont turn. He has tried to pull, pry, and unscrew with no luck. Does anyone know how the pin or if the pin comes out?

If its like my 93 it is a roll pin that holds the line in. It can be a PITA to remove. And the 2 torx bolts on top are annoying, I just replaced mine with normal hex head bolts.

Thanks. Is there away of pushing the roll pin threw or did it have to be pulled? And on the torx bolts, in the next hour were heading to buy replacements for those and get an easy out for exhaust bolt that broke at manifold. Oh, what a learning experience for him...

Supposedly, the pin doesn't come out, the retaining nut comes off the pin and then the whole assembly slides off.

The retaining nut looks like a spring nut and more then likely will be sacrificed upon removal and will need to be replaced. The new bearing might even come with a new one.

There is a retaining nut that has already been removed. Now there is just a pin that is holding the slave from removal and that is separate from the one that had the nut.

The Only Cotter or roll pin I see anyone anywhere talking about is the one that holds the lines to the assembly.

I will assume you have looked at the new one to see what it looks like and that this pin isn't there. usually with roll pins you need to push them out either from the front or back, but roll pins aren't usually very good at holding things in laterally which makes me think it is an alignment pin which may just be rusted into the assembly.

We had nothing holding the hydraulic lines that came out the hole on the drivers side of bellhousing, which I thought maybe the P.O. had removed and not replaced them. I was wondering if it was an alignment pin, but then wouldnt the slave just slide off once the retaining nut is taken off the other bolt/pin? And the new slave has nothing with it, not even the hydraulic lines to exit the bellhousing.

I can't find anywhere on line with a picture of the second pin you are talking about. I also only see the BA 10/5 for the 4.2 and the ax 5 for the 2.5 listed for 89.

Actually I found a reference saying during 89 was when the AX 15 came on line for the YJ's My guess is that MIGHT be the M in the VIN instead of the T.

Thanks for your help. The 89 is a late 89 Sahara and we have had problems getting parts that are related to tranny because parts stores dont recognize an ax-15 in 89. My son had made a mistake about nut holding slave in and he found retaining clip on that pin after clearing away more hydraulic soaked dirt. Popped clip and it came right off. Thanks again!

The AX15 did come online for late in the 89 production year. VIM M vs T tells you when the engine was manufatured. M is late 88 to mid 89', T is mid 89 thru 90 leading to the 4.0L change from what I understand. My VIN is M and came from AMC with the BA-10, maybe a PO did the AX swap which could be the reason for your issue.

This 1989 Sahara has "T" with 4.2 and AX15. My 1990 Wrangler has "T" in the VIN and it also has 4.2 and AX15.

My 89 "T" has a BA 10 and I bought it in December of 1988 so that sounds a bit off. I have heard that there are like 80% T and 20% M's out there.


And Congrats on getting the damnable thing out. Hope in goes smoother. remember not to cut those straps.

Mine is an 89 built in late 88 with VIN M. The info I got was when decoding my VIN.... I guess it was just to make us all ask questions.
