vk throw out bearing help

[Cugno]

Hi just, I got a m-76 manual conversion for my vk calais with a brand new heavy duty clutch kit.
However after a week of driving, the clutch wouldn't engage properly, even with the cable fully adjusted.
I took out the box and realized the throw out bearing had actually cracked where it pivots on the clutch fork.
I was told to put a VN throw out in, because there longer and ill have to push down on the pedal less to engage the clutch. Will this work? Or will it push in the pressure plate? Any suggestions?
Thanks guys.

It only stopped engaging the clutch properly due to damage, I dont see why you should use one that's longer to do the same job.

Biggest problem with the newer throwout bearings is they are plastic housings.
Early ones were all metal.
Try to find a good working old type and chuck it in.
I'm leaning towards the idea of heavy duty clutch is too much strain on the the plastic type of throwout bearing.

yeah I don't understand because the throw out came with the heavy duty clutch. I was hoping for the VN one because I can buy one brand new that's metal. Every where I've called don't have any used ones or new metal ones. Hopefully the VN one doesn't push the pressure plate to much or at all. Is the pivot ball of the bell housing adjustable? I know some have threads on them, but I cant see how to adjust mine.
Thanks

I had the same problem. I went to RPM in Belmont WA and they gave me a toyota one that is all metal and has worked perfectly ever since. If I can find the part number will post it up but at a guess I think they were used on the toyota version of the starfire four but thats just my guess.
