Clutch Slipping Wierdness

[Cam]

Not sure if this should go in this section. Apologies if not.

I bought my 92 Accord with the h22a swap and had also had a transmission conversion. auto to manual. When I got it the clutch seemed to engage a long way out on the pedal movement. Only 5 or 10 cm from the fully out position. I had thought this was because of clutch wear.

Anyway, last week I had a new clutch and flywheel installed. Because of a few reasons. One of which being that it made a screaching noise every time I took off or changed gears. I put in a hd clutch kit and new flywheel and the noise is gone and most of the time it is all good. However, after driving through some peak hour traffic or something where I've had to ride the clutch a fair bit something slips. I think it's the clutch. Any throttle over 15% or so makes it slip. Until I get home. Then I let it sit and its ok next time I drive. Like something is heating up.

Also, the new clutch still engages at the same point on the pedal. I'm not sure what type of gearbox I have since the code is missing off it. Has anyone thats done a trans conversion heard of anything like this? Does anyone think this slipping could be related to the point that the clutch is engaging on the pedal? Maybe it isn't clamping it as much as it should. Can the clutch engage point be adjusted? Could it be a master/slave cylinder mismatch or something?

Thanks for any help or suggestions. I have a feeling this is the underlying reason why the previous pressure plate and flywheel were badly worn when they were taken out and I don't want it to happen again.

hi
I got a 93 accord with jdm h22 in it. my tranny is also from lude. I had the kinda similar problem. the clutch was making noise when i release it. i took it to the mechanic and they said the master cylinder gone bad. but i don't know about ur case. this freeking noise get on my nurve. especially in the rush hour traffic

Thanks for the reply. The noise is gone. I think I know what you are referring to though and it was worse than like a squeak. I had this on my previous car. The noise I had sounded like tyres slipping. Anyway, irrelevant cuz that is fixed. Must have been either the throw out bearing or something in the clutch mechanism. Current problem is the new clutch slipping.

i really hope someone knows about this because i just installed an XTD Stage 3 clutch and an ACT proLite Flywheel on my h22a and its doing the exact same thing, only mine causes the car to shake a little while its slipping.

Edit: well it shakes more than a little bit. almost like the pressure plate isnt clamping down enough, and i still have the same engagement point that the other clutch had.

[LawdoG247]

Did you ever fix the slippage problem?

i had a similar problem when it geot hot and it wasnt the slave cylinder it was the adjustment for the pedal under the dash to tight and it slips it might take a few trys and a few road tests to get it adjusted right get a manual it tells you how to do it, and this was how i fixed it and it been 4 months and no slip as for the dude with the shacking lude swap you either got a warped flywheel or bad clutch kit, take it to a tranny shop shit road test are free just take it to a good shop that you or someone else know about

thats what i'm gonna do as soon as i get some free time away from work, this Army crap blows.

This is nice, Newbs helping Newbs. Welcome guys, I wanted to ask you cam what kind of clutch did you put in there? Remember some require a 500 mile breakin period. Also observe what rpms the clutch is slipping.

[dwsaccord]

my best friend said his truck did the same thing but when I bought it, it was fine. But when he borrowed it he said it still did it. More than anything check how you drive, every clutch is different and you need to figure out how it is. Also hi performance clutches will slip for a while until they are broken in, mine slipped a little but not really bad for like a thousand miles on my coupe and then it was just fine. Oh and one other thing unless your clutch is released all the way your foot should be nowhere near the pushing on the gas pedal unless you at a stop and then proceed to go again in first which in that case make sure you are not revving to high or releasing to slow.

the squeking noise is either fromt he throwoutbearing/release bearing or the pressure plate....not the master cylinder.

it says so in the Hanes manual.

wow lots of replys over the last few days. thanks ppl. I havn't had the problem again since posting however i havn't been in much traffic.

Gen4acclude: I know where you mean. I'll give that a go thanks.

AcclipseH23: I got a street disc with hd pressure plate and a 12lb flywheel shipped all the way over from the USA from lsd Motorsport. It slips at just about any rpm. I mainly notice it when I'm cruising say in 4th at about 2300 rpm and go to accelerate a bit. It has been in for about 1000 k's now.

There is definitely a problem with the engage point though. I think it is this that also makes it very hard to go at slow speeds. Clutch is kinda jumpy. Anyway. I'll have a muck around with that adjustment under the dash and post up the results.

I have a gut feeling that tells me that the pressure plate was not torqued down to specs. Try the pedal because maybe the slave cylinder is pushing on the fork thus the pressure plate cannot make full contact. If that does not work the whole job needs to be done over. Also you said there was a whine...that does nto sound good to me at all. I am almost positive you will need to remove the clutch again.

[dwsaccord]

ok I think I know what the problem is when you put the clutch in did it slide down the spline easily or was it firm? if it was firm thats wrong the clutch needs to be able to move slightly. If it was firm the throw out bearing will squeel because it cannot force the clutch back in position and cause excess use of the clutch disc making it overheat I had this problem in my turbo civic coupe and what I did was pull out the clutch disc and file down the grooves in the center of the clutch disc slightly in order to cause the disc to slide on the tranny spline easily. This fixed the problem.

Well I had a fiddle with that stuff on the pedal. Will go for a drive later on to see how it is. Feels a little better with the little test drive I did. While under there i noticed the pedal sensor wasn't connected. Could this be an issue? Also, the sound I mentioned isn't there anymore it was fixed when the new clutch kit went in.

Either way I'm going to take it back to the workshop that did it and get them to have a look. Hopefully if what Acclipse says is right they will fix it for free.

[KillerCam282]

Thats my guess as to why the clutch would just start slipping for no apparent reason. If the Pressure Plate is too loose then the clutch will not have enought friction to hold on to the flywheel.
