Technical 1986 Fiat 126 Clutch Disengagement issues.

[RensdeKooker]

Hi All,

New to the forum but not new to this car, did quite a lot on it brake wise and paint/rust wise so happy to be able to drive it again. I do have problems with disengaging the clutch tho.

When the problem first popped up it was a simple fix with adjusting the clutch cable adjustment nut. That helped me for a couple weeks, then however the problem popped up again. Adjusting the cable wouldnt fix this problem, so here is the problem described.

When not driving for a while(Think 1 to 2 weeks) the clutch disengages without a problem and shifting works like intended. However after 10-20 minutes on the road the clutch wont fully disengage as if the cable isnt set up correctly. Since this is not a static problem but a periodic problem I wont know what to do.

In a couple weeks I'll get some time to crawl underneath and get a look at the flywheel/clutch. Anybody recognize this problem and what should I look for? If I cannot find the source of the problem I will go ahead and replace the clutch/pressuregroup and pressurebearing. Dont know when and if that has been done yet in this car.

Hope you guys and gals have any ideas.
Kind greetings,

Rens

I believe so, according to the image you posted above. The cable is placed correctly to the bellhousing using the clip from nr.13 That is the only place I can see it being connected.

When the weather is a bit more hospitable I will jack up the car again and check underneath to be sure though.

So, the weather is great today so I went and jacked up the car. Here are some pictures, to my eye everything looks in order and not moving.

The clip on the bellhousing:

And the end of the tunnel and start of the black part of the clutch cable assembly:

I also took a moment to remove the flywheel cover and the original problem of oil seems to be gone, solved when i replaced the clutch assembly.

Whilst the cover was removed i was able to adjust the bolt on the clutch cable so that the pressure bearing was resting lightly on the clutch springs.

Then i depressed the clutch and checked back on the pressure bearing. After depressing the clutch, the pressure bearing would not be resting on the springs anymore and i had to slightly readjust the bolt. This seems like me the most likely culprit. But i still cant figure out why.
