Trying to make up a adapter for my flywheel puller.
I have lost the part that sits in the threaded end of the crank. What size is the hole in the end of the crank (with small clearance)

Also what is the flywheel bolt size please.
I could check but I am at work and I want to get the bit made this afternoon.

Thanks

Just measured mine and there is a blank non threaded section at the top of the hole that measures 6.58mm deep from the end face of the crank. The blank hole is 15.56mm in diameter. I'm not sure about the thread but its an uncommon size i think. I think minisport sell a tap for it.
hope that helps you

Um - use a crank bolt as the thrust piece... wind it in plenty (but obviously not enough to stop the flywheel from shifting) ... job done..
