My clutch started slipping today, it has been installed for 2 months and it has 3,000 kms on it. It is a new Honda disc with ap2 pressure plate, and 8 lb flywheel. I think it is grease related. It slips in lower gears as soon as VTEC kicks in, it holds at high rpms as long as I don't hit VTEC at WOT. I was out a week ago in warmer weather driving pretty hard and it never skipped a beat, today the temps are quite a bit cooler and it seems like VTEC engages harder and the slipping is now happening. IF it is grease related I don't know why it just started happening after 3000 kms of use. Is there any way the grease can burn off over time without having to drop the tranny again ?, or any other suggestions ?. Thanks for reading.

Update: I checked my clutch rod freeplay and it had tightened up. I think the hard driving I did one week ago caused the freeplay to tighten up. I definitely had some play in it prior to that, but today I found it to have closed right up. I shortened the clutch rod and the slipping has disappeared. Thanks for all of the replies. Much appreciated, I love this forum

 

Wow can't catch a break huh everything is adjusted properly on the clutch pedal? Sure its just not cold tires loosing traction?

 

You got that right brother, someone is trying to give me sign about this car and I'm too stubborn to listen I guess, lol.

It was definitely clutch slippage, at first I thought it was the tires but I can't sense them spinning by sound or feel and I can't hear them spinning. At the Wine tour meet it didn't slip at all despite our hard driving, today during easy driving it would slip as soon as I hit the VTEC engagement point. With the cold temps and my cold air snorkel the car was pulling harder today. If I ease into VTEC it doesn't slip.

I did replace the clutch master cylinder and braided clutch line about 2 weeks ago, I'll check the clutch adjustment but I can't think there is anything wrong with it, unless it has air in the system. Thanks for the suggestion.

 

I'm not sure I think our car has 2 clutch adjustments but I would make sure the clutch pedal has no a bit of play when released.also did you check the slave and ball to make sure there is smooth movement and nothing getting hung up. Also I wonder if its possible to spray something inside the clutch fork hole to clean the surface ?

 

I did have the clutch rod clearance tightened up a bit so reduce free-play I can try to add more play to it. I haven't gotten into the slave recently since the new clutch install 2 months ago, it was smooth at that time but on occassion I have had a snapping type noise when releasing the clutch after coming to a stop in neutral, I can't get it to repeat itself once it happens and it doesn't happen every time, just once and a while. I could never figure out what the snapping noise was.

Myflys2k suggested trying some brake cleaner, that would have to go through the fork opening, I guess it's worth a try. Thanks for the continued advice

 

You need some play in the pedal otherwise the clutch will never disengage fully. The noise could be the slave or fork catching I'm not sure or even the splines...but I'm sure this was greased right.

 

Only thing about trying to clean grease off of a clutch disc, is that it'll only get the surface. Due to all the fibers in a disc, the grease/oil gets embedded in the disc and once it heats up again, it'll pull to the surface all over again. Not to mention, in order to get any grease off the disc, the clutch has to come apart anyway since it's sandwiched in between the PP and Flywheel.

 

yeah with limited room to work with on the fork opening I doubt I'd get to the affected parts. Maybe I should just do some feathering of the clutch and burn off some of the surface, if the tranny comes off the clutch has to be replaced anyways. Thanks for the continued advice on this Jordan, happy Birthday BTW , same day as my sister, lol.

 

Yeah Jordan and I have not been able to figure out what the snapping noise is, it only happens intermitently. I've got a spare slave sitting around doing nothing I can try to swap it out. I definitely greased the splines, just thiking I may have over done it on the grease but it didn't seem like a lot to me at the time.

If it wasn't for bad luck I'd have no luck at all

 

Hopefully it doesn't come down to pulling the tranny. I'm really hoping since you have a different flywheel and clutch setup all that is off is the adjustment. Hard to say for sure though.

Thanks! I bet your sister has a few years on me though.
