clutch disc discrepancy ea82

Featured Replies

i have two different clutch discs in my garage, both of which are same in OD. one has 4 springs, the other has 6. could someone splain this to me? thanx folks, RV

do the splines in the middle of the clutch disk match up? as far as I know thats the major difference between subie clutches.

oh ya my bad. splines are identical. checked with clutch tool. the 4 spring came out of one of my cars (loyale probably), and the other disc/pressure plate came with the spare motor i got with the wifes new 88. hmmmmm.......

yeah, probably just different makes. I know my GL's transmission takes clutch disks from a 01 Ej22 but NOT from the standard ea82 clutch kit.

weird. 3.7 gears or something? or did the parts guy think he knew what he was talking about and in reality ( as it so often happens) he did not.

naw I got the xt6 clutch kit for my EJ22 swap, that didn't match the splines on the input shaft of the transmission. I picked up the regular GL kit, that didn't fit. I tried the clutch that came on my ej22, it fit just fine so I got a new one for that.

ahh ej swap, no wonder. im still driving my dinosaurs around. so, next question; is the one with 6 springs inherently better than one with 4? forgive me, i still havent mastered the physics and internal clutch disc characteristics. i just know how to take em off and put em on. thickness is close enough to call it a push. thanx for the input btw

There are lots of variations in the design of clutch disks. The 6 spring one could be a heavy duty version, it could be a light duty version, or it could just be that manufacturers design.

ok cool, i think ill throw it in just to see. when i have multiple used items i usually dont buy new, that and $$ sucks these days. also, the springs appear to be the same size on both, it stands to reason that 6 would work 50% better than 4. but, like i said i really dont kno

The only different clutch disks were the 2wd ones, they were smaller diameter.

 

Pick whichever disk has the most thickness left to it.
