If I may bring a point to everyone's attention and that is the clutch halves that are currently being sold through various sellers may well be a reject as [b]just about every new replacement unit that's been located around Australia at this present time is not good for service.

If it's the smaller 5/8 variant you require I would first test fit it onto the shaft of the engine prior to Thrust bearing fitment and painting and see if it's a nice snug fit with no wobble whatsoever. If there's any wobble then take it back and get a refund as there's no way you can fix it and it only replicates what an old flogged out clutch half would do in every way. GA Spares are well aware of this issue and are accepting returns and refunds to the original purchasers which are businesses buying from them. The business must refund you the end user.

If you are buying a new engine then I would strongly recommend you purchase the larger 3/4 shaft power plant and then get the clutch half to suit as there's no issues with the 3/4 units at all. I've just had to do this for my neighbours machine that I've finished restoring.

What the problem is with the smaller 5/8 castings is that they come straight out of a mould ready to fit and are not line bored, whilst the 3/4 units are all originally 5/8 units and then line bored out to 3/4. This means there's no element of error with those. Sadly all these clutches are being made in good ol' China and their quality control isn't very good at all and these units are suffering shrinkage out of the mould, thus the original 5/8 centre hole is not perfect at all.

This Thread will be removed from here once GA Spares have sorted this Australia wide problem out.
