Release Bearing Retainer/Grease Your Throwout Bearings!!!!
So I figured I’d put this post up to help anyone who winds up in the same situation that I was/am in. Also, thanks to tac_shift for helping me out with this one.
Last October after finishing my turbo build, my car made an awful squealing noise, and the clutch wouldn’t disengage most of the time but the noises and behaviors of the car were extremely inconsistent. I bought an endoscope and will post the pictures I got with it. I saw what I thought was the innermost sleeve of the throwout bearing out of the release bearing assembly and sitting on the clutch side of the clutch assembly. I was wrong. After talking with tac_shift, I figured out it was the outer sleeve of the aluminum “snout” that the throwout bearing rides on. This sleeve is pressed onto the aluminum snout, and is made of steel, as to protect the aluminum snout so that your release bearing doesn’t damage the aluminum snout and it rides along it. Some of the 2G DSM cars have this sleeve as well. This IS a replaceable part, and I read a thread on the DSM forum about someone just re installed the old sleeve. The part number is MD716349. When the sleeve came off, it dug into my clutch, wearing a ring into it, and somehow caused the throwout bearing to eat away at the pressure plate (I will post pictures of both). The sleeve also mushroomed, causing a crowning of both the inside and outside of the sleeve. Why did this happen? I didn’t grease my throwout bearing. Happy ending though, I found the sleeve on mitsubishipartssource.com and I ordered it today. Also, I bought a new McLeod clutch assembly that’s rated for a little higher power, which will be nice since I just put a new 20G turbo in, a new slave cylinder, a new master cylinder and the braided line between the both without the damper.
Just figured I’d give you guys a little info about this because the few threads I’ve seen about it, everyone was playing Sherlock Holmes trying to find out what was going on, even AFTER pulling the transmission apart (no offense to those guys, cause I did the same thing). So, do your wallet a favor and just buy an endoscope before you spend $450 in vain trying to fix an issue.
