Walkenvol Posted January 9, 2013 Share Posted January 9, 2013 Is this mod worth it. Gathering parts together for a build. I've already got an ax-15 and bellhousing with the internal clutch slave. Should I make the effort to source external bellhousing and associated parts? If so, why do some reccomend the Dodge Dakota bellhousing over the later model Jeep? I've done a lot of looking, but I've not found a great write up on the mod. Anyone got one book marked? Link to comment Share on other sites More sharing options...
Geonovast Posted January 9, 2013 Share Posted January 9, 2013 One, yes, it's worth it. Two, the Dakota housing has absolutely nothing to do with the clutch slave. It is necessary to mount the AX-15 behind the 2.5 or 2.8. Dakota bell will be useless for a 4.0. Link to comment Share on other sites More sharing options...
Blue88Comanche Posted January 9, 2013 Share Posted January 9, 2013 I have not swapped to external slave yet but plan to. I say if you can find the parts then grab them.. unless you just like removing your transmission every time the internal slave bites the dust :fs2: Link to comment Share on other sites More sharing options...

The bell housing was very hard to find in this area and took me months. I finally spotted an ad for a late model AX15 tranny for sale and called the guy and offered to just buy the bell housing..He thought they were one piece but when he looked at it, he said yes so I got it. And he still was able to sell the tranny to someone else. And when I installed it, I used Dot 5 silicone fluid for it. Link to comment Share on other sites More sharing options...

RDAN1 Posted January 9, 2013 Share Posted January 9, 2013 I hope you got the bearing retainer with it. I didn't. I had to buy a used one from a tranny rebuild shop. Link to comment Share on other sites More sharing options...
Geonovast Posted January 9, 2013 Share Posted January 9, 2013 I didn't. I had to buy a used one from a tranny rebuild shop. Ah, ok. Just making sure you got one in there. I'd hate to see the result of the external slave setup with the internal retainer. Link to comment Share on other sites More sharing options...

1987Comanche Posted January 10, 2013 Share Posted January 10, 2013 I have some pics of the comparison and swap I can post if you want. The swap itself is easy...finding the correct parts can be difficult. Link to comment Share on other sites More sharing options...
Walkenvol Posted January 10, 2013 Author Share Posted January 10, 2013 I have some pics of the comparison and swap I can post if you want. Yes please. Since this is applicable to Cherokees and Wranglers, there has to be a good write up on the net somewhere...I just can't find it? Link to comment Share on other sites More sharing options...
Geonovast Posted January 10, 2013 Share Posted January 10, 2013 There's probably not too many write-ups because it's fairly straightforward. You can even get pre-assembled and bled master/line/slaves for the stupid things. Putting the transmission itself in is no different than an internal slave.

Walkenvol Posted January 10, 2013 Author Share Posted January 10, 2013 I'm with you on the general work involved, not really different from typical clutch work. From the threads I've read, there are some details concerning the different parts that will interchange. Also, some folks appeared to fit the new external slave onto the existing internal hose. Another option was offered by Advanced Adaptors http://www.advancead...lease-bearings/ per this thread http://nash-offroad....rnal-slave.html to mate the old clutch master to the new external slave. Obviously having a complete donor vehicle to grab everything needed would be the best option, but that's hard to source. So is there anything else needed besides the following; - bellhousing - shift fork - spring clips on each end of the throw out fork - throwout bearing - external style bearing retainer - slave cylinder - hydro line or way to mate ex line to new external slave It would be helpful when sourcing the parts required to have a list of the exact parts needed and all the vehicles and year models containing these parts. I read where the bellhousing for a NV3550 interchanges with the AX-15 which would open up more possibilities. Also read the release arm doesnt matter if its a 4 or 6 cyl, they are the same supposedly confirmed at the dealer as same part number. Also found this as Potential Donors - AX-15e: -1994-1999 XJ 6-242 -1994-1995 YJ 6-242 -1997-1998 TJ 6-242 -1993-1994.5 ZJ 6-242 NV3550: -2000-2001 XJ 6-242 -1999-2005 TJ 6-242 And since AX-15 is a Toyota design then there may be donors there also? Also found this concerning the hydraulics; The newer style m/c, slave cylinder come as a complete unit. Don't buy it from Mopar, I bought mine from the dealer, did my sons a month later, bought it from CarQuest & it was about 1/2 the price. The CarQuest unit came in the same box, oem part for 1/2 the $. Link to comment Share on other sites More sharing options...
1987Comanche Posted January 11, 2013 Share Posted January 11, 2013 Internal Slave AX-15 (slave cyl removed) Parts from external slave AX-15 External slave bellhousing next to internal slave AX-15: Clean the external slave bearing retainer and replace the input shaft seal: Use RTV to seal external slave bearing retainer to trans. It is a direct fit. Then install bellhousing. I'd recommending replacing the ball stud, shift fork, and clip that retains the fork to the ball stud. Purchase a clutch kit for a '96 4.0. You'll need to buy a separate pilot bearing with 0.590" ID and 1.055" OD. You will also need a 29/64" drill bit to open up the hole on the clutch master cyl. It won't fit the pin on the clutch pedal unless you drill it oversize. Link to comment Share on other sites More sharing options...

1987Comanche Posted January 12, 2013 Share Posted January 12, 2013 Maybe we could pin this thread in the project section. Might make it easier for others with the same question(s) to find... Link to comment Share on other sites More sharing options...

skidoo_j Posted January 12, 2013 Share Posted January 12, 2013 Using the 89 master or a master from the donor? Link to comment Share on other sites More sharing options...
1987Comanche Posted January 14, 2013 Share Posted January 14, 2013 Thought you might recognize the trans :D I used the one piece master & slave assy from the donor. I investigated other ways to do this conversion but it seems that bleeding the slave is nearly impossible if you cut & splice. Link to comment Share on other sites More sharing options...
