The other odd thing about my engine (type4) is that the front bearing (Number 4 main bearing, pulley end) was omitted completely. In place of the front bearing the prop hub lay in it's place. The hub is approximately the same diameter is the bearing shell.
Hey Orma - I have often marveled at your engine - has been doing well in 110LR for ages. Always figured it must be a really good one - now you find out that it is anything but. There is a lesson in there somewhere. I am keen to see the comment from the more informed members re the missing front bearing - surely this cannot be right. What acted as an oil seal - was there a shaft seal? Take care Steve J Askies"AT"microlink.zm
