ax15 swap

[dancome433]

i know alot of you guys have done this, so i need help. found out that my pukegoat ba10/5 is giving me hell with the clutch, won't engage in gear, leaks when i bleed the clutch, so I'm really frustrated to say the least. so i decided to swap an ax15 in, i found one on CL, but doesnt have a bellhousing. now for my question, will the bell housing from my pukegoat work for the ax15? and i read earlier that it will work, but will my new clutch kit(slave cylinder, throwout bearing, flywheel, etc) from my pukegoat work for the ax15? can't think of any other questions but when i do ill ask

The clutch and flywheel will work, the bellhousing and the slave assembly will not. Keep in mind that a TJ/YJ trans will clock the t-case up a bit.

[Geonovast]

Since you need to buy the bellhousing and all the clutch components, get and external setup! Should run you about the same cost-wise, and you'll be much happier with it.

[dancome433]

alright cool thanks you guys, so i should probably see if i can find a complete ax15 out of an xj

Also make sure you get the clutch master slave cylinder and hose. You will also need to do something with the t-case linkage, which is where I am at. Also keep in mind that if you buy a later model clutch master cylinder you will need to enlage the clutch pedal hole, or you can do like I am trying to do and reuse your old master by using the Advance Adapters flex line.. will let you know how this works out once the part arrives.. which should be any day.

I adapted the old clutch line to the late model clutch line using a $2 compression fitting from the hardware store. :thumbsup:

Is the pilot bearing the same between the two? I am getting ready to do my 4x4 swap and am trying to thin down what I have to buy.

I used the one that quadratec site listed as the part number. It worked great

After the Renix years I think the pilot bearing size changed. It has been suggested that a CJ 304V8 size will work though so it shoud still be readily available.

[Pete M]

Yup, my 99 AX-15 installed using a 70 something CJ pilot bushing. It's a $2 part. :thumbsup:

[watchamakalit]

Awesome. Thanks guys. I am hoping to be able to find one today and maybe this weekend start my swap.

I think you left the 'C' out (for clock). ;)

 

 

YJ/TJ's actually clock their T-cases down a little vs XJ/MJ's.

You can redrill the patturn for an XJ's clocking,

you'll also need to get an XJ's t-case shifter, or try to modify the BA's to fit.

 

I don't know if a (shorter) XJ AX-15 (transmission) shifter lever will work with a YJ/TJ AX-15 tranny.

 

The did not interchange (XJ to YJ) on BA 10-5's, tho on those you could take the shifter handle apart, and swap just the shorter XJ shifter arm onto the YJ's lower pivot. (creating a higher effort shifter)

[pingpong]

Thats the part I am up to.. trying to figure out what to do with the t-case shifter. The trans I have didnt have the shifter part on it. Right now I am reaching down into the trans tunnel shifting the t-case... Not exactly ideal.

With my (01 XJ) NV3550 I was able to connect a rod directly from the T-case shift arm to the floor mounted shifter, without the (tranny specific) in-between linkage.

 

I never got beyond the hacked togeter screwed & tackwelded rod, but here it is:

 

 

 

The shifter works backwards like this (full back position is now 2wd, full forward is 4wd low), and IIRC, I had to re-index the t-case shifter arm on the T-case, but it was pretty simple.

 

I changed the shifter handle on my factory shifter, but it's not really necessary for the mod to work.

 

IIRC, there is a writeup by someone else here on the same mod.

Thanks man. I was thinking of doing something similar to what you just showed me. Currently side lined with a hurt back so, it will be a day or two befor I can wrench again.

:thumbsup: hope you feel better soon (been sidelined most of this year, so I know it sucks :ack: ).

 

Look for that other thread too, seems that guy put his to use more.

 

My MJ's been pretty much driveway jewelry since I did the mod, so I can't say it won't try to pop out when wheeling in 4low, etc/etc.

I think he redrilled the plate/lever on the T-case too (I didn't).

Thanks for posting up the links... I got some idea working in my head now... On top of a buddy going to the j-yard to pick the stok parts

just as soon as it drops below 100 degrees up here... ;)

 

I might try to leave work early tomorrow and go (but it's supposed to rain, so we'll see)

Its all good man...

After doing some more searching... decided too look in my Summit catalog. I figure for less then 15 bucks I should be able to pull off a trick shifter linkage.

I order a left and right female rod end. I will use some 1/4 all thread and see how it works. the parts will be here in a few days...I will keep you all posted

The clutch and flywheel will work, the bellhousing and the slave assembly will not. Keep in mind that a TJ/YJ trans will clock the t-case up a bit.

 

The sensor on top of the bellhousing...is that the CPS? Doesn't it read the gaps in the flywheel? If my memory serves me correctly, the gaps seemed different between the 94 XJ flywheel and the 90 MJ flywheel in my case. I'll assume it has to do with Renix v/s AMC? In either case, I reinstalled the MJ flywheel just to be safe. Am I way off here?

[watchamakalit]

Will a pilot bearing for a TJ with an AX-15 work? Just trying to simplify what I am asking for when I go to the parts store.

I don't think it will, but I am not 100% sure. I used a Timken PB77HD Pilot Bushing for a 73 CJ with 304 V8. They should be able to cross reference that Timken number to a cheaper one if you want, but it shouldn't be that expensive. Just make sure to use a brass drift on something non-marring when you install it.

Yes, you are correct. That is the crankshaft position sensor and you must keep the Renix flywheel and Renix CPS with the Renix computer. :thumbsup:

Both the outer and inner pilot bearing/bushing diameters changed between the Renix years and the TJ years. I used the CJ pilot bushing and it works out just perfect. :D
