AX-15 New Clutch issues

[Tex06]

Ok, I lost 1st so I decided it was time to update to an external slave setup.  After getting a junkyark AX-15 out of a '96 XJ I rebuilt it, installed with a new clutch/pressure plate, external slave, new master cylinder (as mine was leaking) and reused the line from the JY parts I pulled.  Also new flywheel (for a '92 Jeep MJ).

 

My issue is:  In 1st and reverse gears, my clutch is slipping and I can smell it burning immediately after I stop.  2nd-5th seem ok, although I haven't gone to a parking lot yet and "punched it" in 3rd or 4th to see if the rpms raise without the speed doing the same.

 

Any ideas as to what it could be?  I pre-bled the master/slave setup before I installed it and have only driven maybe 20 miles with it so far (to work and back).  Pedal feels ok, engage might be a little high, might not be (close to the top of the stroke, usually when I replace a clutch in vehicles it moves down to the floor).  I can drive it right now, I was planning on putting 50-100 miles on the clutch and see if it "seats" but I've never had a vehicle do this to me before.

 

 

Summary:

 

New:

External slave

Master Cylinder

Clutch pressure plate

Clutch friction disc

throw out bearing

pilot bearing

flywheel

rebuilt tranny

 

Old:

Master cylinder/slave line

Transfer case

Rest of truck pretty much

Did you have the flywheel resurfaced? If it was scored deeply it could cause this.

It's new as stated in the first post.

Seems like the clutch is settling in, 1st gear is much better than before.  Reverse is still a little funny, esp if the wheels are turned.  Is it possible my front axle is locking up on me?  I have a Dana 30 HP up front, I don't believe it's a vacuum disconnect (has a single rubber line running to it that has a vent on it).

NVM....just realized I was driving around in 4-hi and not 2-HI.  Jeep has a different shift pattern than my Chevy    :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:  :doh:

Clutch shouldn't have slipped at all ever, wether in 2 or 4wd.

Ehh, it's not uncommon to have them slip at first while they "set". We used to take customers cars out to the parking lot and do a lot of takeoffs after a clutch job just to work out any little imperfections and limit chatter due to the new surfaces meeting.
