Clutch not disengaging

[bratjie]

Hi guy's, need help here, I recently overhauled an 1700 engine and sent the flywheel and clutch kit off to the clutch guys for skimming and recon of clutch and pressure plate. After return of the flywheel and clutch kit the clutch does not disengage. I have checked and tried all reccomendations on the site, from new cable, cable tubing, fork and replacement kit, Bowden cable adjustment clutch travel, correct release bearing, you name it. Every article covered and checked. However I normally only send Type 1 kits and flywheels to the particular shop and have never experienced any problems. Today I had another one (Kombi) done and ,,,, same problem. Took it back to the shop and they showed and explained all there is to know even showing that it releases on their test bench which by the way is a hydraulic press and who knows what travel they are giving it. Taking all that into consideration I can only come up with one remaining problem, did a test by adjusting the clutch as far as it would go ( I know that the release bearing is now running against the forks of the pressure plate) the cable being tight as a guitar string when you depress the clutch now one can feel the familiar knack (for a lack of a better word) when the fingers go past the point when the pressure plate normally releases the clutch about mid pedal. Now we can select gears!!! My conclusion thus is that the friction area being skimmed and the outer ring where the pressure plate bolts onto should be skimmed by the same amount, right? From their summary the height between friction area on the flywheel and bolt on area height must be 22mm, and I summise that this is probably correct for type 1. What I need to know now is, is that spec the same for a Kombi flywheel? What is the correct measurement between the friction area and the bolt on area on the Kombi flywheel? Any advice greatly appreciated.

This is a 914 Flywheel, but the shelf "a" is 22.5mm.

It is more likely the clutch disc is too thick.

Good luck

This is all I could find for clutch disc thickness.

Thx guy's, sorry but I omitted to mention that it has a 215mm dia clutch plate, would this mean a different flywheel then?, definitely not tipe 1, 180mm, 200mm or even 228 cluchplate (which is Wasserboxer)

Another item to check would be the connection of clutch cable at the pedal. A reversed lever arm there could result in not having
adequate travel of the release bearing at the trans.

all of the above plus

- the disc is too tight on the input splines so it can't slide to release. Did you put some a light amount of moly or moly grease on it and make sure it slide smoothly on the input shaft? We see this issue once a year or so.

- the pilot bearing is not allowing the input shaft to spin freely. Did you replace it, and grease it?

The lever arm is the right way round with no excessive wear on the clevis pin, also both clutches were checked and movers freely on the input shaft with slight greasing, pilot shafts locating correct and deep enough into the flywheel and new bearings fitted and greased, I'm now without any other options.
