OS Giken Clutch issue

[Bigzavs]

hey guys, i just installed an osgiken triple on my car, went ahead and bled the system with the new slave cylinder, and for one, it feels like pushing against a wall, pedal is stiff as hell.

pedal currently has about 1" of travel before engaging the system.

problem is, i cant get the car in gear while running, with the pedal all the way to the ground. although it goes into gear fine while off, if i leave it in gear, push the pedal down, and try to start it, it just jumps.

i realize this means the clutch isnt disengaging, but will that 1" of play on the pedal make up for it? also the OSGiken has an adjustable ball thing on the slave rod (ya that sounds messed up, cant think of another way to put it) that i can probably use to put the throwout closer to the pressure plate to start off with.

if anyones got some ideas, let me know

you dind't say anything about the adjustment screw on the master (on the pedal)

Sounds like you are pushing down too much fluid...

 

[Bigzavs]

what way should i do that?

never messed with that before

Pull the small cotter key from the pin on the MC shaft that connects to the brake pedal. Use some wrenches to loosen the lock nut, then the clevis/plunger rod for the MC can be screwed in or unscrewed by hand. Adjust it, re-tighten lock nut, push pin back through, cotter key, done.

Yes, you need to adjust the threaded rod on the master pedal. In my case however, there wasn't enough adjustment and I had to install a shim behind the flywheel, as well as install a slightly longer slave rod.

Its not the pedal. If you're pushing it and it feels like a brick wall is because its catching on something and not allowing the slave to work. Double check the push/pull converter.

its working, i had the inspection cover off last night while bleeding it

the pedal goes to the floor, its just stiff as hell i kinda expected it after how my single disk osgiken felt

I have the same issue with my supra!!!! I cant get it into gear while running. I looked at the slave and i can see it moving the pressure plate. I adjusted it with freeplay as the TSRM says and it still does it and i did it with out freeplay and its the same. I have no clue what i'm doing wrong either. I ordered a new flywheel and i'm going to rip the trans out and see what happens after. Hopefully i can figure it out.


This is with a driftmotion master cyl, slave, braided clutch line all new, ACT clutch with full face disk btw

Don't have to pull the cotter pin to adjust the freeplay, just gotta loosen the lock nut and turn the shaft (should be easy as it doesn't sound preloaded).

I know there is some other adjustments with the OS Giken, but I haven't seen any directions for it...

Try lengthening the adjustment rod for the slave cylinder.

how stiff was the pedal feel on your quad disc?

What type of OS Giken clutch do you have?

It was very stiff, and luckily it was engaging correctly the first time I installed it. I just guessed on all of the adjustments. From there it took a good week to get it adjusted so it was somewhat drivable . It just takes a lot of tinkering.

You're right, it's not pre-loaded. However, mine wouldn't spin unless I pulled the assy. apart. Then again, my black car was a P.O.S..

TS3B if i was told correctly

good to hear, its significantly stiffer than my OSG single disk, i guess i get to start messing with the master and slave today............yay
