Hey guys, late summer my clutch started slipping under power sporadically, so I figured it must be the throwout bearing, seems i was right as mine has severe wear on its inner bore and it jams up really easily. the clutch itself looks like it's still got tons of life left but I'll replace it and the flywheel anyway, the flywheel has quite a bit of play in it.
A little info about the car, it's a 2006 (12/05 build) 115k miles.
But while I was in there I decided to pull SMG hydraulics apart and replace any o-rings/seals I could find. I went through, measured the sizes of the o-rings and seems like I can find viton ones on mcmaster for all of them except I can't find the piston seals for the selector rods. Anyone know a source for these? I inspected mine and they don't look to be worn but I figure if I can source them for a decent price might as well.
I'm referring to these guys
And now some pictures of what I found inside:
Looks like at some point in the past water had gotten in behind my pump motor
also the motor hub has a ton of wear in it, so I'll have to make a new one
not sure why there was only rust where the hub adapter goes since the rest of the motor face was clean
looks like there was a ton of wear on the motor shaft, and the shaft wasn't fully engaged, i'm guessing getrag made the coupler a little under-size, I will likely make a custom one that's a bit longer
slave cylinder dust boot was fully torn off, looks like these aren't serviceable so I'll have to get a new one
tons of wear on the throwout bearing
but the clutch disks and the pressure plate look like they're in great shape, other than a bit of galling
it's crazy how poor machining quality is on these components, but i guess they're ok enough as at least the o-rings between the shifter valve block and the piston block didn't seem to be leaking, but the shifter block was leaking against the transmission, i had tons of mtl leaking around the top
and here's the scary bit, I need to replace the wires on the shift rod position sensor, but mine has cracks in it, so i'm hoping it doesn't break while i'm working on it (it was working fine when i removed the gearbox). I will likely try to seal it up with potting compound or some sort of RTV once it's back in position so water doesn't try to get into the cracks
btw, how does the accumulator work? at the bottom of the input hole it's blocked off, or are there small holes leading to sideways?
looks like this car had that clutch pressure plate failure where the spacer pucks fall out and start flinging around the bell housing
I'm going to try to document this project here, and I absolutely welcome any advice, except for "don't do this if you don't know what you're doing"
