The OSC Dump Truck (89 Sport Truck 2.5L)

[OSCDumpTruck]

Thank you very much! Have wanted to make a build thread for a long time now. I really do like the 2.5, it’s a great motor for running around town. Not having new flywheels available is a bummer.

 

Couple other things I just thought of that I plan on doing.
 

1: I have a full rebuild ready for the throttle body (injector, regulator, seals, etc)

2: Someday swap in my non-disconnect front axle that’s been sitting in my shed. I converted my stock disconnect one to a solid axle shaft in 2021. The first seal lasted a couple months. The second one is still going strong!

3. Harmonic balancer.

Nahhh we don’t need new ones. A light sanding with 1000grit does the trick for surfacing

I was pretty bummed about it a week ago! We’ll keep them on the road one way or another.

 

My plan was to clean up my flywheel and use a clutch for a 94 2.5 XJ with my TBI flywheel. From what I’ve gathered researching, that should work.

 

On the ZJs, they had the external slave in 93. No conversion needed when I did that swap on my 98, just a CPS for a 98 ax15 XJ.

If youre wanting to do a external slave conversion, find a 84-86 with a manual set up and youll be able to use that set up on the 87-90 bell houses just fine. I did such on my 88 MJ just fine and man do I love that swap! I thing on this will be finding the ball pivot for the clutch fork and I was able to use later year chrysler ball pivot on my 84 when I swapped to the TBI bell house also with no issues.
