Clutch Concern

Postby Rocketman_47 » Fri Apr 14, 2017 7:22 am

Hey guys, I just bought this killer S15. It has a LT1 383 with a T56 6-speed. The concern I have is that the clutch doesn't engage until the pedal is literally almost all the way out. I can barely touch the pedal and the clutch starts to engage. I know it is a hydraulic setup but is there a way to adjust the pedal ?

Thanks
Zack

Bleed the hydraulic system is one thing you can do. If mileage is unknown then i'd look at a new clutch

If it had air in it, it would be the opposite effect, hard to release. I'd suspect either a stack up of tolerances that put it there, or just a weak stock clutch. Example, my Miata has a Stage 3 clutch, my fiancee's has a stock replacement I put in about 3 years ago...mine starts grabbing just off the floor, hers is pretty much not grabbing until right near the top, but both are good clutches. :? 8)

Just wondering since I am in the middle of doing a manual from auto swap with a LT4. Is there an adjustable link between the clutch pedal and the clutch master cylinder? On mine I had to adjust it after bleeding the system to my liking.

I don't know if it's adjustable as is, but you can MAKE it adjustable, :thumbup:

Well, I am taking the truck in next Tuesday for a diagnosis on the Clutch. It has progressively gotten so bad over the last few times I've driven it that I can no longer drive it. I spoke to the shop who deals with these issues and he has said based on my description the throw-out bearing is not fully engaging and that is exactly how it feels. It is like the clutch is not fully released. Even when I am cruising and gently accelerate, it starts slipping like crazy until I let off the gas. From an dead start, it also chatters really bad so who knows. I am hoping it is just a slave cylinder or throw-out bearing issue. I will report back as soon as I find out.

Wrong clutch master cylinder? I bought a Wilwood master cylinder for my swap and found out it didn't have enough volume and pressure for my clutch and ended up going with a C6 OEM master cylinder.

Well, here's the verdict. The once high dollar aluminum flywheel is trash, full of cracks, the disc is burned completely up, the pilot bearing chewed up the trans input shaft end. Ultimately, the previous owner must have dogged the sh_t out of it for it to be in this condition. So, now $1,000.00 and a week away still, I will have a factory stock replacement clutch setup.

That's pretty much what I was thinking. I won't be driving it like a 16 year old anyway so there is no need to spend $2K for a McLeod setup.

Yeah that's a racing set up. Much more reliable with a stock unit in there

Here's whats left of the previous owners BS claim that this clutch had 3,000 miles on it or less, LOL. Why can't people just be honest. I did save the aluminum flywheel. At some point I will replace the surface and more than likely reuse it.

Hahahaha, not bad for a complete clutch assembly with 3,000 miles "or less".
