I have replaced everything new on the clutch system, but the clutch won't engage fully, you can force it in gear, but the wheels are still turning. I know it's not a hydraulic problem because I have the slave cylinder pushed in with a puller and the pedal is rock solid. Everything being flywheel, clutch, pressure plate, throw-out, bearing, clutch fork, slave cylinder, master cylinder. This has the pull pressure plate system. It seems to me it`s not pulling enough.

Hi,

I'm not sure what is happening. You indicated the wheels are still turning but it won't engage. I'm confused because if the clutch won't engage, the wheels wouldn't turn. Maybe I'm thinking of this backward, but when you force it into gear indicates to me that the clutch won't disengage the engine/transmission.

So, if it won't disengage requiring you to force it into gear and everything is new, my primary suspect would be the pressure plate. You tested the slave, and the clutch fork is new, which leaves the issue with the pressure plate.

I'm sorry, I'm just trying to figure out exactly what is happening.

Let me know.

Joe

Hey Joe, thanks for getting back with me. I was a mechanic for 50 years I`ve never ran into this situation before but this my first reverse system. I'm like you I`m trying to figure this out myself. I don't know if you've done one of these systems but to me the clutch fork has about an 1"-1 1/2" of travel before it engages the throw-out bearing is that normal? The clutch kit I bought was on Ebay. It was supposedly a stage 1 clutch do you think that might be the problem and should I go OE? I haven't done a clutch in a few years so I`m not in touch with which aftermarket company to use but back in the 1970's in my Drag racing days I used Zoom clutches what would be your suggestion on that? Thanks again for getting back with me you reaffirmed what I was thinking I`m going to replace the clutch, PP, and the throw-out bearing.

Hi,

The distance between the fork and release bearing sounds excessive. I did a little research and found something of interest.

This vehicle came with either a 5-speed or 6-speed manual transmission. I looked at the exploded views and the clutch forks are different. If you have the 5-speed but the parts are for the 6-speed, the clutch fork appears to be flat. The 5-speed is curved. That would explain the excessive play.

Take a look at the two pics below. Pic 1 is the 6-speed and pic 2 is the 5-speed. It's just a theory, but it makes sense. If you got it from eBay, the parts could have been mixed up.

Also, I always like to keep the OEM parts in the vehicle. I guess I'm just getting old. LOL

Let me know.

Joe
