What's needed for a sm420 conversion/fj40? - Pirate4x4.Com : 4x4 and Off-Road Forum

Berg · 08-20-2001, 08:23 AM

Would someone list what is needed for a SM420 conversion in a 76 FJ40/4 speed/2f?
All I have collected so far is a 3 speed bellhousing. Need to know the following...
1. What clutch/pressure plate/flywheel?
2. what throw-out bearing/retainer/sleeve?
3. what clutch arm should be used
4. What pilot bearing
5. What T/case adapter should I buy?

thanks

I have a brand new extra Wardens adapter plate for sale for $200, Warden wants like $350. I'll post a pic of it when I get back from my business trip on Friday if you're interested.

I'm just buttoning up an SM420/Dana18 swap to FJ60. We used the 3 speed bell housing, AA pilot bearing (the stock one is too short), Classic cruiser's bearing retainer index ring (which Warden's said I didn't really need), Warden's machined down sleeve for the clutch T.O. bearing to slide on, 10.5" Centerforce clutch disc for GM car, the stock '85 pressure plate and t.o. bearing, and the Novak SM420 to D18 adapter. One interesting part of the swap was the driveshafts I picked up and installed today. Spicer 1310 U joints on the t.case end and Toy L.C. u joints on the pig end. Cool. The driveshafts grew in the swap (yokes not so far appart) with 30.25" front shaft and a 43" rear driveshaft. Perfect fit. Long slip splines. The rear output on the D18 is offset like the Toy output. It doesn't hang as low though. With a pretty much stock angle of the drivetrain the t.case only hangs about an inch below the line of the frame rails. It's very close to being straight back to the rr pig. Maybe 1/2" off- not enough to worry about. The reason we went with the D18 was the 2.46 low gears, upgradable to several lower geared sets. Oh yes, and Jeep parts are SO MUCH cheaper than any Toyota parts, even without the gold plating. 8<) As it is now he'll have 62:1 final drive with 3.70 pigs. We installed SOA, lockers and 35's last year. Respectable. The thing that amazes me is how much smaller the cast iron SM420/D18 combo is than the huge aluminum monstrosity of the Toy 4spd./split t.case combo.
I'll be doing a writeup for 4x4wire.com shortly with pics. the title? "Out with the new and in with the old". Makes sense to me.
regards, as always, jefe

as of now im first in line at keiths plate! ill email you too kieth.

wngrog · 08-21-2001, 05:24 AM

Sounds AWESOME Jefe!

I wish I had done the D18 in years past.....

I don't know why more cruiser types don't use it. It also has a 4:1 kit sor it and dual sticks!

Killer swap. Post a link here when you finish your writup!

Thanks for keeping us posted on the results.

If not one else bought the plate yet put my ass in line.

KeithF · 08-24-2001, 08:41 AM

bennet passed on the adaptor plate because he needed one for a 4speed. the one I have is for a 3speed so dcruiser138 you're next in line so let me know.

70Cruzer · 08-24-2001, 10:59 AM
