OM617 to AX15/NV3550/NSG370/T18 Adapter Kit will mate your OM617 donor motor to any AX15, NSG370 (2005-2006 4.0L), or NV3550 manual transmission. It also works with the Jeep/AMC T18 and similar T-Series transmissions with the 4.2L I6 bolt pattern.
The kit includes:
-Aluminum Adapter Plate
-Galvanneal starter spacer
-Hardware and custom ARP Flywheel Bolts
-15mm/17mm Input Shaft Adapter Sleeve (optional)
You supply a Ø1" OD pilot bearing from an early 1990's Jeep 4.0L (ex. Timken SCE1295).
There are 2 flywheel options - an AX15 or a T18 (LUK part numbers LFW193 and LFW192, respectively). If running an NSG370, you'll have to convert to the AX15 clutch/flywheel.
The flywheels are machined with a custom bolt pattern and are ready to be bolted on. It is highly recommended that you mark the posiiton of your OM617 flexplate in relation to your crankshaft before removing. This new flywheel comes neutral balanced, and you may not have any issues running it as-is, but your safest bet is to have it "match balanced" to the OM617 flexplate.
Custom ARP bolts are uitilized for the crankshaft spacer and flywheel.
If you are running an older 15mm or 17mm input shaft model, a sleeve will be included to adapt your input shaft up to 3/4". The sleeve is a high-tolerance shrink fit and will not come off without a puller.
