Hi, after fitting a new exedy cltuch i noticed my revs would die when i pushed in the clutch. After some reading i thought it was the IAC valve so i cleaned that up on my accord type r h22 engine. No better. I was driving around and the engine siezed. Couldnt crank the engine by hand...I took out the lump and removed everything until i found the cause.. The Flywheel side thrust washer had melted the crank to the bearing housing...I havent managed to remove it yet as its solid, but when i do and get the crank re-machined, what can i do to avoid this happening again. I measured the thrust bearing on the exedy clutch and its much the same as the standard one. anyone had this problem or an easy way to unweld the crank without detroying the bottom end?
Cheers

 

Well, that thrust washer takes a lot of abuse. When you push the clutch in, all the force required to disengage the clutch is also placed on that thrust washer. My guess would be you installed something incorrectly when you did the clutch. That is in my opinion highly probable because the two parts are connected to each other, metaphorically speaking.

 

yeah i thought that also but ive had a mate round who is fantasic with cars and he said all looks good. if i can get the crank out without to much damage ill double check everything when i put it all back together. cheers

 

When i first fitted the clutch i did notcice the revs would drop when i engaged clutch. Could the combination of a new clutch plate and springs put force on a thrust washer already with 150k miles under its belt cause this>?

 

Did you go from a stock clutch to a high performance clutch?

Do you have a habit of holding the clutch in at stop lights as opposed to shifting to neutral and letting the clutch out?

If I'm remembering correctly a stock clutch puts about 1800lbs of force on that thrust bearing so holding that for 30 seconds at a stop light doesn't help it. That number can only goes up with aftermarket performance clutches.

Side note, regardless of what your mate says, what you are experiencing in regard to the thrust washer being welded to the crank is not normal. They don't just do that after 150k miles.

 

Something was definitely wrong with install or bad pressure plate.. Ive been running a stage 2 for 2 years now and have not had any problem.. Next time i pull the motor im gonna drop the pan and look at the thrust washers.. Was there alot of metal shavings in the pan? Might have to pull the motor apart and clean it out really well.. Goodluck mate..

 

Nah it was a standard exedy clutch mate. Ive double checked everyhting it all looks ok but obv something is wrong somewhere. Im gonna call in a mechanic to have a look just to see if he can spot anything i think...Stupid question but are there only 2 thrust washers for the crank? one either side of the journal nearest the fly?
