Cleaning oil off a clutch

My HPOP exploded on my 7.3 manual trans, and after I got it back from the shop the clutch will slip in fifth gear above 75% throttle as soon as the RPM is over 2000 or so and I’m making some power. I suspect oil got on the clutch as it was pretty much everywhere else. I’ve read about using brake cleaner but I’m not sure the best way to go about actually getting it on the clutch with-out actually pulling the transmission out. Any ideas on how to spray it in there or other ideas how to get the oil off like pouring a 2 liter of coke into the valley and letting that run down there onto the clutch (yes I did hear that once.) Thanks.

Re: Cleaning oil off a clutch

To clean it completely you are going to have to pull it.

There are no shortcuts to it. Over time if it is oil it should burn or wear off.

Replace it .Once oil gets into the lining very hard to get rid of, it will not operate smoothly under a load.

Use caution with brake cleaner and heat. It makes a highly toxic gas that will kill you in seconds.

Re: Cleaning oil off a clutch

as said, the only way to properly clean it is to pull the trans.
and if you are going to pull the trans, you might as well just replace the disc.

what year truck?
if it is an 97 or older, it most likely has a dual mass flywheel, and the DMF is probably bad.

It’s an 02. Thanks for the heads up about the toxic gas. At least I know it’s probably just gonna need a new clutch so I can start planning for that. It’s still totally drivable for now so Im gonna hold off on the full replacement for now and I’ll update the thread in case anyone is curious and for posterity.

If that has a dual mass flywheel I would look that over real close too. In my 93 I had it slip pulling a load if got into it, flywheel was shot.

Good caution.
Though that's the chlorinated kind.
Non-chlorinated is good to go.

Re: Cleaning oil off a clutch

I believe it makes phosgene gas. Never had a problem with it though and I've been breathing the sh*t for years. Flashing off of manifolds, caught a few things on fire, even flame throwing and cought a dudes hair on fire once. True story by the way, his wife made me pay for his hair cut. Lol, oh man, I just now remembered the sight. He was running around screaming like a girl with flames coming off his head. Swear to God that's true. It was hilarious. That was actually carb cleaner though.

Anyways, thankfully i still got my lungs so far.

Re: Cleaning oil off a clutch

He didn't even know that his hair was on fire. He just saw his jacket on fire so he screamed and put that out. Then he's standing there with his jacket smoking and his head is still on fire and he didn't even know it. I had to run over there and tap it out for him. Then his jacket and head were both smoking and he sat there in silence for about ten seconds. I think he was shocked I had actually done it. I was shocked too, I didn't expect him to go up like a dead Christmas tree.

He so pissed he went home for the day.
