So here is my writeup on the NP435 + doubler swap into my Jeep XJ. Whilst I was at it I also swapped in a NP203/NP205 doubler transfercase setup. For reference my jeep was originally equipped with the AW4 automatic transmission.
To begin with I will start with a list of clutch related parts I used for the swap. I’m going to try and make this list as inclusive as possible but I might miss a thing or two here and there. For some of the parts I’m including part numbers for reference.
This was the hardest part about the whole swap. I researched what parts I would need for some time. It helped that I had helped a buddy of mine put a 435 into his wrangler. We worked out must of the bugs on his swap.
- 3 AN Slave Cylinder Fitting For Jeep 716130F
- 42" Stainless Hose 716130H
- Clutch Hydraulic Slave Cylinder for Jeep Cherokee XJ and CJ 16909.01
- Clutch Fork Boots for Jeep 16918.03
- Master Clutch Kit for Jeep CJ 1976-79, 6 or 8 CYL, 10.50" 16902.07
- Clutch Fork Return Outer Spring For Jeep 16919.14
- Pivot Stud, Bellhousing: 1972-75 CJ with 6 or 8 cylinders 3184913
- Clutch master cylinder for 89 Jeep Cherokee
- Pilot bushing from Novak A6932A
- Flywheel for 89 Jeep Cherokee
NOTE: My bellhousing came with a pivot ball as well as return spring and boot so I didn’t have to purchase those but they will be needed.
Anyways first thing is first, here is some background info on the swap just incase you were wondering.
The T176 bellhousing is drilled and tapped for several different transmissions, one of witch is the large Ford Pattern. The T150 has pilot holes for two of the bolts and nothing for the others but has the material cast into the bellhousing so it can be drilled and tapped to work. I’d recommend going with the T176 bellhousing as it makes things much simpler but a T150 can be made to work.
The NP435 makes a good choice for a tranny swap into a jeep due to the availability of a factory bellhousing for the swap and relatively small length of the NP435. Due to its height though it can be a pain, as the pictures will show later. The Ford NP435 has a 1-1/16" diameter, ten spline input shaft witch is the same as the late 70’s jeeps. Be careful though there are also jeep clutches with the 1-1/8” input so make sure before you buy.
For my setup I decided to go with the 203/205 doubler setup as it gave me the best strength cheapest cost and a 4:1 crawl in the t-cases. It is an extremely heavy setup though. The NP435 weighs about 135lbs and the 203/205 weigh in at close to 250 with adapters. But I get 32spline front and rear outputs as well as triple sticks with some minor modifications to the 205 shift rods.
Well enough with the talk, I know most people probably won’t read a thing and will just look at the pics so here goes.
