Looks like the way to fix it properly is to identify and fit the new bearing blocks.
Anyone got a pic of the differences in the bearing blocks so that I can see if the stock in the local model shop is old or new design ?
cheers
You have a PM Bob. Beside this, the difference is that the new block (left) has a bigger hole at the inside, the size of the bearing is like those in the mid-shaft.
