How Do I Get Clutch Fork Free Play?

Ok, I had a clutch issue and have put everything back together (even managed to get the gearbox in by myself on the garage floor!).

The Exedy guys said the pressure plate forks had the thrust bearing resting on it constantly - I never had any slippage issues. Before GB was taken off and also once re-installed, I noticed the slave cylinder slowly pushes the fork so the bearing rests on the pressure plate forks (as suggested by Exedy). There isn't mush pressure holding it there hence the no slipping of the clutch.

Now I believe the fork should have some free play and not 'rest' against the pressure plate forks right?

There is a little free play in the pedal like there should be and clutch take up point is about 2/3 - 3/4 of the pedal stroke (closer to the floor). I understand I can adjust the master cylinder piston to change pedal freeplay and take up point, but I don't see how this will stop the slave from extending fully. Could there be air in the system?

Can anyone shed any light as to whats wrong and what can be done?

I just don't wanna go bleeding the system if it needs it or adjusting the master cylinder piston rod.

Thanks peeps!

I'm unsure about the 33, but the 32 has a nipple on the master which has to be bled first, otherwise you'll end up with a spongy clutch feel due to an air lock.

Get back to me if you can because I'd be interested to know if the 33 has this nipple as well - curious like a cat.

Yes, my R33 definately has a bleed nipple on the master clutch cylinder.

And I have been informed that the thrust/throw out bearing should sit up against the pressure plate with minimal force, so seems there is no real problem...yay!

by "freeplay" you should be able to push the fork forward to lift it of the clutch.. ie, as long as its not bottomed out and the fork can be moved by hand its ok.

it will always rest on the pressure plate. just aslong as its got some movment.. if you unbolt the slave it should flop about

It does exactly that and is all back together driving fine. Cheers for advice guys.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
