Hey guys, I'm having some problems with my rx-vert. I've read and searched but I'm just asking to make sure this is whats wrong. ok, I recently put in a brand new gripforce clutch for my '88 vert, and everything was peachy for about 6000 miles. then, out of no where, it starts slipping in the mornings and on cold starts. It will usually only last for about 15 to 30 mins. When the car warms up, the clutch feels almost normal. since this started, I've bled and replaced the fluid in the clutch cylinders a few times. It never really helped. Then I replaced the clutch slave cylinder, and the clutch seemed a little stronger, but still would slip, though not as much,. when i drive the car at start-up, it will slip up to 1.5-3k above @full pedal where its supposed to be, but then acts like the clutch engages, and it equalizes back to where its supposed to be. I never smell burning clutch, so I think its just having problems engaging. I'm thinking that I'll have to replace the Master Cylinder. Judging from my info on the problem, does that seem like the problem? Or am I looking at more problems than just hydro? Thanks again!

 

It sounds like you need to adjust your clutch pedal.

 

I don't think theres any adjustment needed since the clutch system is operated by brake fluid. I could be wrong though.

 

Of course you can adjust your clutch pedal. Do you have a little freeplay?

 

could that be my problem? it would be awesome if that's the only thing wrong.. I'll check it out. hopefully I'll save some moula

 

NOO!

well.. checked the freeplay.. its normal. still think it might be the master cyl? thanks

 

Yah, if it was tight enough it could cause it to slip. Maybe when it warms up, things expand just enough to give you the clearance you need for slip-free operation?

edit - Ha, you're quick. Nevermind about that I guess.

 

yea, most of the time I just let it warm up. Sometimes though I'll start it up and the clutch will feel like I just put a new one in it, other times it acts like I have 10 miles left on the clutch,slipping like crazy. I love my vert, but it's starting to p me off.

 

Tell us more about the clutch parts themselves. Gripforce? Was it reman stuff?

 

did you resurface your flywheel when you did your clutch? did you 100% make sure that all the mating surfaces were clean when you installed the clutch plate to the flywheel and the pressure plate to the clutch plate? if they were dirty at all this will shorten the clutch life quite a bit. how many miles on the car?

 

1st part= No, The mechanic installing the clutch said it was not nessesary to machine the flywheel,but he said it was glazed from heat, and he cleaned it up. 2nd part= Im sure he did he was ASE. 3rd part= My 88 vert has 142k on it.

I do remember that when the mechanic replaced the clutch, he said that the old clutch still had plenty of miles on it and said it looked like it didn't need replaced, even though at that time it was doing the same thing its doing now. it was replaced at 136k in march.

 

Well.. I bought a clutch master cylinder, and its still wanting to slip. anyone have any ideas what it might be still? I've replaced the entire clutch cylinder system, and still slipping..

 

Jeez, I don't know then. The glazed flywheel surface? Did the mechanic turn it?

Contamination like was mentioned above? Although if your previous clutch was acting the same, makes me wonder.

 

I think, with everything thats going on, I think that either the cars flywheel may have warped, or I might have a busted rear crankshaft oil seal, or just a cheap crap clutch. I hope its neither of the first two things, but im thinking it might be.

 

I don't want to hijack the thread, but is the clutch and brake system tied together somehow? (Believe me, I know it sounds like I'm a moron...I am.) I only ask because I'm having problems with my brakes ONLY when I hold the clutch down AND then brake. I should have the right master cylinder tomorrow.

 

well, the brakes and clutch are 2 separate systems. I am 95% sure that they do not share fluid at any point.. if your having problems at the same time, I would check the assembly that holds the pedals under the dash..
The clutch seems to *slowly* get better since I installed the master cyl. maybe the bad M.S. let the clutch slip and glaze the flywheel. Just to ask while I can, anyone ever hear of a new clutch wearing out after 6k. I don't drive hard, but I do drive spiritedly everyone let me know if they think they may know whats wrong.

 

LOL.. this post was less than 5 months ago, I put a new clutch in, and it just started SLIPPING AGAIN! jeez.. What would cause the clutch to slip, but not part of the clutch kit? I replaced both master and slave clutch cylinders, and still the problem is happening... I really think It might be having problems with the release bearing control arm or whatever holds it together! anyone ever have problems like this before??

 

You should take it apart..AGAIN..check the Clutch fork assembly.Also are you Losing engine oil..like More than Normal?..or have you checked the Tranny to see if your Fluid level is Down?..it could be a rear Engine seal,Or a Front Trans Seal that is Putting Fluid onto your clutch and ,making it slip..These parts should be looked at When you drop the Transmission..
