SMF Con release bearings

Hi All
About 2 years ago now I converted my GT JTD to the single mass flywheel courtesy of a GTA clutch I had in the garage and an Autolusso solid flywheel. The car has driven great ever since and overall I'm very happy with it. after about Eighteen months however the clutch pedal went to the floor, there was nothing wrong with the hydraulics so the gearbox had to come off and what I found was that one of the "ears" had broken off the release bearing. A whole new clutch was put in "just for good measure" and the car back on the road feeling great again.
Sadly 6 months later and the same thing again. This time I'm only replacing the bearing as the clutch is virtually as new but it still looks like the clutch fork is tearing the ears off the release bearing.
When I originally changed the flywheel, I changed the slave cylinder to a GTA spec one as well to match. I'm sure I read somewhere that when Autolusso do SMF conversions they also change the slave cylinder but maybe not to the GTA one, if anyone knows another reason this could be happening (other than the wrong slave cylinder) I'd be grateful for your input. if you've experienced this and cured it please let me know how. Thanks

Infamy, Infamy, They've all got it In For me!

You're pushing the clutch bearing too deep?

get a v6 fork to compare to the diesel fork

A reasonable suggestion thanks; and by coincidence I did have one in the garage so I've put it on in the spirit of try anything once. I have to say though ( this is without getting the micrometer out ) with the pair side to side, visually I could see no difference what so ever and according to Eper they are the same part number

I still lean towards the opinion that the only thing that will alter the extremes and range of release bearing travel would be altering the length of the slave cylinder shaft or changing the slave/master cylinder combination, and that's if it is the cause. I've never heard of anyone having this problem before and there must have been a good few conversions done by now.
