Thrust Bearing
 

Why is it my thrust bearing a.k.a "burger bearing" always torn off?? is it possible because of clutch gap? need help..thanks:cry::cry:

its a combination of things gap too big is one reason and spring is too tight so when the spring comes out and it is too tight the gap is too big and unloads with such force its smashing against the bearing. good rule of thumb big gap looser spring small gap tighter spring.. always use thrust greese, so incase the clutch is bad and gets so hot which can blow the balls off the bearing the greese will help protect from the heat...

What is your endplay?

TQ BRO!

around 0.5mm...

Pack it with high temp wheel bearing grease and never blow one again.

I'm serious, it works. And don't skimp on the grease, be liberal.

thats a lot, most iver heard is .3mm endplay

Thats your problem, that sucker is getting smashed everytime the clutch engages and it wont last very long!!! your supposed to run .05 to .15mm. If you can drop the endplay to somewhere in that range and grease it up you shouldn't have a problem.

Zero endplay ispossible:

Spec on each model differs. .8-1mm seems to be the most common. I actually have it alot tighter at .03mm and maintain geasing the bearing offen. I've been useing this endplay for 25years, and have no problem with it.

Zero endplay is possible, but not recommeded, for overheating(bluish color) may occur. Can be done. TB that comes apart or dicentagrates cuz of eccessive endplay of over 1mm.

Centax style clutches didn't exist 25 years ago. :D

CENTAX CLUCHES HAVE NOT BEEN OUT FOR 25 YEARS, LMAO

DITTO, didnt read down, my bad.

The small wave springs I have found are very soft, they just give enough tension to push the clutchbell up and does keep the balls of the thrustbearing perfectly in the groove of the discs. The problem with to much play is when the clutch engages the balls of the bearing have to find the groove, at that moment a lot of forces are on the ring holding the balls and then after a few times the balls come loose...
I have these springs on all my clutches.

Another trick I have used for years is use a brass 10x5mm washer between the 2 steel discs, works perfectly and does not need any maintenance. You can find these brass rings at any hardware store at the screws section beside the steel screws and washers.
