what do throwout bearings taste like mommy?

[monstaru]

'cause monstaru sure likes to eat them.......i wonder if they have a grape flavor,maybe tangerine.wow that would be neat. it would also be neat if i didn't have to change them every six months.like i have for the past year and a half.and am about to in a moment.again.for the third time.

two trannies,one 5 spd,one 4 spd.have eaten a throwout bearing.excuse me ,the 4 spd ate two.awesomely brand new clutch on a 4 spd,still ate one,newer clutch on the 5 spd,still ate one.i don't get it.i clean my input shaft off,replace spring clip dealybobbers,put new throwout bearing on,drive for a fewthousand and end up not being able to push in the clutch at all eventually.limp home.start over again.wtF...............bueller,bueller,bueller?????????????

What kind of abuse are you subjecting it to? Water, dirt, etc?

Do you lube the shaft (oops) before you put it together?

[GeneralDisorder]

Do you have the dust plate on the bottom of the bell-housing to keep out major junk? And do you have the rubber cover for the timing mark hole? And how's the condition of the clutch fork boot?

 

Also - are you using a goodly amount of grease in and around the bearing? Should be on the shaft, and on both spots where the fork contacts it.

 

They do go out more frequently if you are running through water and mud and stuff, but the rubber covers, and the bell-housing dust plate help a lot.

 

Try using an OEM part if you have been using aftermarket stuff. I think a lot of the bearings are just crap to begin with.

 

If you are running a 4 speed, I hear you can use the 5 speed clutch and flywheel setup, and run a Nissan 720 release bearing... so I've read in other posts anyhow. Might be more rugged - IDK.

first of all ,thanks for all of the reminders guys(it is easy to overlook the dumb stuff).and on the four spd i ran a dust plate and ran the rubber timing hole cover.the 5 spd had both until this last engine change when i lost the damn rubber ,and the dust plate would not fit again(for some dang reason),i even had it modified to go over the bigger flywheel.anyways,in my process i start from the easiest to the hardest.today i started with the easiest(the clutch cable) and was ready to work towards the hardest.i just got done putting in an entirely different pedal box from the parts brat and found that the 82 pedal box had a different clutch cable from the 86(which by the way is a biatch to get in in comparison to the 82).so i got it in and it seems to function properly.i am about to go on a test drive.i'll check in later.cheers

[monstaru]

averted disaster.did i mention that i have had two incidents where i though it was a throwout now and have gotten no farther than the cable.......DO NOT BUY NAPA CLUTCH CABLES

[Roundeye]

Are you setting the free-play? If no free-play is present, the bearing will always ride against the fingers and NEVER get any rest. Make sure your cable is slightly slack when at rest.

[GeneralDisorder]

Yes - the slight cable slack is important, as is the hill-holder cable, or a return spring to keep the bearing from riding on the pressure plate all the time.

 

I agree - aftermarket cables suck - I've been getting mine at the dealer and strangely enough they are cheaper too. Like $13 for the last one I bought. $17 if your dealer doesn't do wholesale for you. And make sure to route the cable under the coolant hoses, and the steering linkage.

Make sure your bearing is made in Japan or the US. I bought a clutch set and it came with a bearing that said made in China. I ditched the bearing for a Japanese one.
