I recently had an ACT HDSS street disc, with streetlight flywheel installed on my Evo IX. After the install it seemed like the clutch was dragging because it was very difficult to get into any gear at a dead stop. I brought it back to the shop and they said they readjusted the clutch per factory specs. It still seemed like it was dragging because it was tough to get into gear from a stop. I took a stab at adjusting the clutch myself it seems much smoother now but I have it adjusted with the rod fully extended will this be a problem? I'm hoping after the clutch has been broken in it'll become smoother and I can readjust it so its not fully extended. Trying to engage reverse is the most difficult. Thanks for your input.

 

How high off the floor does it engage?

My ACT HDSS engages pretty far off the floor which is what you want. If youre engaging right at the floor or near it then you dont have enough separation between the plates and you'll get drag.

 

if adjusting the pedal doesnt work then you might need a different push rod for your slave cyl. Thats what i had to do to get my act to disengage properly

 

The extended slave rod is a band aid and the wrong way to do things. It basically bottoms out on the slave cylinder preloading the clutch which means you'll always be loading the clutch and wearing the thrust bearing.

 

the weird thing is, is when i got my other rod it was shorter than the stock one. I didn't think it was gonna work but it did.

 

Good info Bro. Ive got a bit of ACT lock out at high RPM & need some adjustment as well

 

Curious where you got the shorter rod from.

 

Can you tell me where you got the rod from?
I brought the car back to the shop and they said they're not able to resolve the issue, they mentioned since it wasn't there before the clutch install it is most likely the clutch, and recommended that I purchase an Exedy twin($1,300) from them and pay additional labor($400) costs to have it installed, and while in there replace the clutch fork. I couldn't believe this. A clutch install is pretty straight forward, I didn't have the issue prior to replacing the clutch. They stated that ACT's are known for this issue, not completely disengaging.

The shop also stated that it could be the sliders for first and second gears, but to determine this would require cracking the transmission for an additional $300.

So please give me your input, should I take the shops advice and go with a new clutch or go to another shop and have them diagnose the problem?

PS I don't want to say the name of the shop but I'll say this they are known well on the forum and don't exactly have the best rep.

 

well ive had a couple issues thruogh out the years with a couple act clutches, mine i had the rod pulled back some so the clutch pedal is off the floor, my engagement point is give or take about half way up...gotta give ur clutch pedal a break, meaning its gotta be off engaging the pressure plate when the clutch pedal isnt pushed down, or else you gonna prematurely wear out the clutch disc or the clutch hub could eventually break

 

The clutch has been adjusted to engage half way through the travel, so there are probably 1-2 inches of play at the top of the travel to push the clutch down.

 

ok so sonuds like its where it needs to be, well my 2 issues i had with my previous act clutches, one was not fully disengaging that was due to a dowel pin in the clutch disc, that was higher then the clutch disc itself causing the clutch not to fully disengage, so when that was replaced with another one i got 3k of not beatin on the car no launching and a 3rd to 4th wot shift busted my clutch hub into about 20 pieces in the end, and tryin to limp it home grinding it gettin into 5th to get home about 30 miles away was interesting but never wanna experience it again, id say if u get ur clutch replaced again, spend the money and buy the ss upper and lower clutch lines, best money ive spent to help the clutch problem.
good luck
