Supporting Memberwhen my McLeod master/slave assembly went bad, it did exactly this. It also started overextending the slave and making the fork grind the pp so bad I couldnt push clutch all the way down
I went back to stock valeo hydros and have had no issues since

I'm gonna pull that manual up on my computer when I get home and go through the trans as best I can and take a look at that, didn't notice it just skimming through
hmm okay, and no fluid loss when the slave goes? it is a stock slave with McLeod master and I was looking for fluids when it first happened but the ground was dry underneath so ruled that out. I don't remember if I've replaced the slave since I've had the car so that very well could be it

Supporting Memberno, no fluid loss, it overextended. the master uses a stock style slave. the stock style slave "self adjusts" for clutch wear. but if it gets too much pressure from the master it can overshoot.
fyi new stock hydros, new clutch. pedal sits 1" lower than brake pedal

I had my slave go bad. No fluid loss whatsoever. I believe if the seal is bad inside it will bypass and not engage.

okay that's good to know, I assumed it would leak fluid if it went bad. hopefully I didn't pull the trans for nothing is there any way to tell if the slave is bad other then the symptoms I am seeing? anything I can look for?
still probably going to have the trans rebuilt/upgraded while I have it out, we'll see what some local shops say about pricing/experience

so took a break from this thing, got burned out and focused on house things for a couple weeks. now I'm motivated and want to get this thing figured out and back together. new slave came today so i decided to get under the car and look things over before i tired putting the trans back in and noticed a dowel pin sitting in the bottom of the bell housing (left it attached to the motor when i pulled the trans). saw that one of the 3 dowel pins was missing from the pressure plate (see pic below), not sure exactly what the dowel pin does, anybody have insight? not sure how i missed it before, but i would assume this couldn't have caused the issues i was having, would it?

Is that scraping around the pressure plate from the dowel pin? I ask because when I put a Street Twin into Call911's car, there was interference with the clutch arm and pressure plate. If the arm was being overextended, that would certainly be your grinding noise. I can't see that dowel causing all that unless it was wedged somewhere tight.

Supporting Memberthat looks exactly like my pressure plate when my slave over extended dude.

yes, the scraping is from last year when the clutch fork bolt backed out and was contacting the pressure plate, so it is unrelated to the current issue. sorry, I knew someone was gonna mention that and should've put a disclaimer lol bolt was loctited and torqued properly and was tight when I pulled the trans this time so ruled that out.
I didn't think that dowel pin could cause the issues I was having, thinking I am just going to reinstall it and move on. I will need to open it up a bit as it just slides in the hole easily right now with no resistance.Last edited by hokeplaya05; 08-28-2018 at 02:11 PM.

well think i figured out the issue guess i didn't look at the clutch good enough, going to email mcleod to see what they say. i have no idea how this happens, other disk looks fine and the input shaft spine on the trans looks good too
