So Im going to be replacing my clutch soon, yesterday my clutch started to slip really bad and i bearly made it home.

Im going to replace the flywheel while im in there. I was looking at napa and Marlin crawler and so heres the guestion.

On napa it says 0.020''
On MC it says 0.026''

Whats the 6 thou difference? Or does it matter?

Thanks.

One more question on post 12

JonnyBoy

I couldn't say if it matters, I went with Beaverton Auto Machine when I did my 3.4 swap.
I wasn't sure if mine could be resurfaced when I took it in to the 'em, it had heat cracks and the original clutch mated to it had been run down 'til the rivets were wearing into the flywheel, but they took a glance at it and said "Hey, no problem, we'll get ya fixed up."
Point is, why do you need a new flywheel? Resurfacing is less expensive and if your clutch just started slipping, you probably didn't damage it very much.

Ive only had this truck for about 8 months and every now and then i could feel my clutch "chattering". So im pretty sure the flywheel is warped. I would just have it resurfaced but I dont want to wait for it. Id just like to get her all done with in a day or 2.

JonnyBoy

The turnaround on my flywheel was a couple hours.

Anyhow, the .026" step will mean the clutch will engage .006" sooner than the .020" step on the Napa flywheel. Doesn't seem like it would make a big difference to me.

I just put in a r151 into my 90 4runner and I used marlins flywheel and 1600 clutch and so far I have been very happy. Some of Marlins clutches grab alot harder and stop it from slipping/smoking. I was happily surprised to find that the pedal and feel stayed the same as a stock.

I also have an account/discount at Napa which is where I got my last clutch for the old transmission. The Napa clutch preformed well on the street but under hard 4wd situations would not engage 1st gear while climbing over a boulder it would just smoke. However after smoking it really bad 3-4 times it still worked.

Ohh..well hmm...im going to hunt down a shop that will do that for me if I cant get one though my friend at napa for cheap.

Do you remember what was the price on the resurfacing?

Tubbyfatty

Yea Im going with a MC 1200lb one. Alot of people have told me about it and say it rocks.

JonnyBoy

It was $36.75. Some shops may be a bit more, some may be a bit less.

Tubbyfatty

Yea I was just lookin for a ballpark on price.

abecedarian

Umm... what is that measurement for? ... warpage? ... runout? ... machining?

Tubbyfatty

Flywheel Step: +.020"

So one last question.

Should i put loctite on the flywheel bolts? What about the pressure plate bolts?

JonnyBoy

I always use loctite on the flywheel bolts, but I didn't for the pressure plate bolts, just torqued them down.

Tubbyfatty

Alright. Whats the torque on the flywheel bolts? 65lbs? I know the pressure plate bolts are around 12-19lbs

JonnyBoy

Yep, 65 is recommended by the FSM.

Thanks.
