0.01 inch = 0.254mm

The limits are 0.05mm to 0.012mm (see here for example http://www.peachparts.com/shopforum/3159307-post23.html)

My advice is to change the bushing as well as the pump - at the moment the combined cost of a sealing kit and a new cam follower arm is more than some prices for a complete new pump.

It would be nice to find that last ball bearing...
