2nd gen manual transmission fix

Mine did the same. Lasted less than 2k miles. I had to rebuild it with a new oring that Clutch Masters provided. CM wouldn't just send a replacement assembly. The oring was a different design from what I pulled out. Coincidence? Absolutely zero consideration from CM about the pulling of the transmission again either.

The next time my trans is out, I’m flushing this thing. My biggest complaint (now that it’s not leaking) is the inconsistency of the engagement point. It’s different practically every shift. Seems very temperature related. At worst, If I wind it up really good between gears, something is happening that keeps the pedal from coming all the way up. Only happens if I rev it up say past 4500 rpm. Pedal stays down, the next shift engages With the pedal just millimeters off the floor. I have to put my foot under the pedal and pull it up.

I’ve bled this thing nine ways from Sunday. Vacuum bleed, pump the master, pressure bleed. There’s no air in the system. I’ve dicked with the adjustment at the pedal plenty as well. The necessary wrenches are permanent fixtures in my cup holder these days. Adjust it up, adjust it down. Places in between. Nothing works. I’ve been driving manual trans vehicles since the late 80’s. Nothing I’ve driven shifts as horrible as this truck with this bearing.

You’ll also note that the OP as well as anyone from CM have all but disappeared from this forum. Another coincidence?

 

I’ve had mine installed for 11 months now and haven’t had any issues. I’m about 6k miles on it

yeah I don’t drive it much since it splits time with my Lexus gx.

 

I have about 30K on my hydrobearing and I’m having this same issue of my clutch pedal sticking to the floor, except mine sticks at any rpm. Pretty annoying for a supposed “fix”. I wish anyone from Clutchmaster would weigh in on these issues. I had mine professionally installed and bled at a very reputable race shop, so I’m certain install and bleed are not the issue. Not to mention it’s been working fine for 30K miles.

 

That stinks, hopefully you guys are the minority. I haven’t had any issues with mine but I also don’t really drive it much.

 

I'd like to see a show of hands of who all/ how many folks have used this kit and are happy with the results and who's used it and it didn't work I guess you could say. I've come across roughly 10+/- that had some kinda failure, like leaking and whatnot. Thanks

 

i like it and happy with it. better than the garbage OEM setup

 

Only issue is adjusting the pedal height and engagement point. Otherwise no more squeal and it has better feel.
I think I have dyslexia because every time I try to think through the adjustment I get lost think of how moving the pedal i or out affects what... I keep trying to get the engagement point closer to the floor without raising the pedal height too much. Gotta take another crack at it.
Installed hydro bearing along with the CM Kevlar clutch kit and LUK (I think) flywheel.

 

I have been running this set up since before Christmas. It’s better than oem being I no long have the awful chirping. only issue is one moment my peddle is soft and will go to firm feeling then quickly to soft.

edit: I will say I was one of the unlucky ones to have the oem set up to completely fail causing for the quill to snap off in the bell housing. I hope I never have to go back to the oem setup.

 

that sucks
fingers crossed mine won't fail but so far it seems to work and no puddles under the truck. Haven't inspected for leaks.
Consistent every time.
Well if there is a better seal design, hopefully that's what they use.
I don't know if lubricants help extend seal life. I installed mine dry which the directions probably state.

Maybe they're not on here because they're busy. I heard they had record-number orders.

for example supposedly some cars spec DuPont Krytox, which I hear is crazy shit, $1k per tub, use a little bit inside a CV axle or sunroof seal; supposedly toxic and stays in your skin pores forever so you have to be careful with it
in other words "you get what you pay for" supposedly $1k grease is better than $3 grease
again IF the seal even needs it

only places I've used grease before are that ask for it
like a brake caliper rebuild
and even then I didn't really care much
quick and dirty on a bench and shop rag, rubbed whatever grease packets came with the seal kit into the bore with my finger
then put the pistons in
was not surgery room operating table level clean, or computer chip factory clean

bled mine a few times at 20psi with decent pressure supply and bleeders opened a varied amount each time, to try and get enough flow rate of fluid exiting sometimes
with plenty of fluid
and new parts like new pressure plate to ensure the TOB is pressing on flat even pressure plate fingers, not bent old ones

I adjusted the pedal height rod with wrenches under the dash after install, and it's stayed at about mid pedal engagement ever since. might re-adjust it a bit later but so far it works.

 

Mines been good and consistent feeling but I've only got about 900 miles on it so far. I think I have noticed some change when I've run the truck for a couple hrs and things get hot but not sure as it's usually short drives for me and I've been breaking in a fairly grabby clutch. Hoping it will stand up well through the winter.

Never had a problem with the bleed. Did one bleed session and it seems to have worked fine.

 

I drive 3-4 different manual setups every week so I don’t notice the difference in clutch pedal position I just get used to it when I drive the Tacoma. If it’s your only driver then you can easily adjust rod length of master cylinder with the all thread.

 

UPDATE: Took the truck into my mechanic and he agreed there was something wrong. Before having to pull the trans to put the stock bits back in, he tried a very thorough bleed. It does feel better now with no pedal sticking. I guess air may have formed in the line or something (not really sure how? I really don’t think I could have boiled my DOT3 with normal daily driving?) Hopefully it’ll be good for another 30K. But honestly I don’t have a lot of faith in it, which is a pretty shitty feeling.

 

So, I put the truck into the air tonight. Another pressure bleed. Pedal has been super inconsistent (like every shift). Also going to try switching to DOT 5.1 Fluid. Sucked the reservoir dry. Added the new fluid. Hooked up the pressure bleeder and then cranked it up into the air and got underneath. I remove the access cover and see this through the inspection hole:



Yeah. Really. This motherfucker is leaking AGAIN!

 

Fuck

 

agreed

 

Not cool at all. Mine isnt leaking, but the inconsistency in pedal feel is getting really old. I agree it is heat related. It's super smooth and silky when you first take off, then after around 15min of driving it starts to get all spongy and almost feels like the engagement point is constantly shifting. I've found at its worst, if I put it in neutral and pump the clutch several times, it helps get a semi normal feel back. Not sure what that means... has anyone had any luck messaging CM about this issue? I cant see them just ignoring a widespread issue with their product like this.

 

Squeeky bearing, breaking off of the input shaft support extension, heavy clutch feel, slipping engagement. (clutch accumulator is usually the culprit there.)

 

Did you delete your clutch accumulator?

 

Yup

 

Probably got air in the system somewhere then, the issue you describe is typically a symptom of dirty accumulator valve on the side of the trans.
