Topic: What would you all do in this situation?

[bammerman]

What is the reason it cannot be adapted?  Is it the flywheel, splines?  I am curious because there is a guy in the 4x4 club who did it and am not sure if he had it machined or what.  Maybe he is blowing smoke up my ass.

the bellhousing pattern is different
tranny input shaft is different too

what did he use to mate the ax-5 to the 6 cyl? the AX15 bellhousing won't bolt on to the AX5 so that's the challenge, i assume you can eventually find a way to get the clutch working. Maybe he got an adapter plate of some sort.

I think the general consensus is that since AX5 is so weak you shouldn't use it behind a 6cyl.

[bammerman]

To be honest I am not sure.  I do not think he had the AX5 I think he had the Peugeot transmission.  All I know is he did a 6cyl swap when he had a 4cyl without changing the transmission (he did end up doing a AX15 conversion about a year later).

dunno anything about the Peugeot tranny. I did a NV3550 conversion behind my 4 banger so thinking of how you would do that backwards presents couple of challenges. the only thing i can think of (but this is just a long shot guess) is if the 4 cyl clutch disk would work with the 6 cyl flywheel and pressure plate then your only remaining problem is to have an adapter for the bellhousing or some bellhousing tha would mate the 6 cyl to the tranny. You cannot use the 4 cyl flywheel (even if the bolt pattern would be the same and regardless of the transmission whether is AX5 or Peugeot) as the 6 cyl has 3 sets of teeth for the crank sensor as opposed to the 4 cyl which has only 2 sets.

I am going with the 225 mile engine with all the electrical and just buying a AX-15 and rebuilding it.

you'll also need either the t-case or the t-case input shaft (i think it's 21 spline for AX5 and 23 for AX15).

Well i found out why I got so much blowby yesterday, bad rings :(


So we are dropping in a fuel injected 4.0 from a cherokee.  Keeping my T-case and changing out the input shaft.  Also in this deal I get the power steering box and powersteering pump. my 4.0 has neither.  will be a nice change.

If you haven't bought the new tcase input shaft, look into just buying a Used NP241 off a blaser,
I'd have to double check but I think it not only has the right input shaft it has the bigger chain and wider
sprockets in it...

It can be a good junkyard upgrade if you find all the right bits...

That isn't a bad idea if I can find a low mileage one.  I only have 70k on my Tcase

He would need to swap parts back and forth to get it to work.  The whole front half will have to be swapped out as GM's are 5 bolt.  The input spline is 27 which won't work either.

I think a better choice would be to look for a NVG-231HD or D.  Dodge used the larger 1.25" chain and sprocket set as well as the 6 gear planetary set (Jeep 3 gear).  The front half could be 6 bolt which is also a plus.  I'm not sure on the spline count but I think it might be 23.  Although when looking at spline count you have to also look into the shaft depth.  There are long, medium and short as well as big bearing and small bearings, which confuse things a bit more.

I thought they used the 231 and AX15 in the Blaser at one point,, Oops Keyboard error.

Blazers used the NVG231-C (Chevy) as opposed to the NVG231-J (Jeep) or NVG231-D (Dodge).  There is also a NVG231-HD but some things like the chain and planetary were also used in the Dodge.

Keep in mind the Dodge application was used with the 318 and NV3500 in the Dakota, Durango and Ram 1500.  I don't believe GM ever used the Aisin AX-15 though.  They used the NV3500 like the Dodges.

[dwtaylorpdx]

Some blaser have T5 tranny  as well, I though ther was a adapter on those that mated to the 231, which it probably did, but not eh right NP231

New hookup!  Found a entire drive train, for 400, and its a manual!  A lot of miles so I am just going to rebuild it but way better now since I get power steering and everything else instead of a bare bones engine.

it is an 85-89 cherokee.  I know I need new motor mounts for the inline 6, but if I am pulling everything from the cherokee is there anything other than that i need?
