Piston ring replacement

[Bob Culver]

Wiith the block removed so you can roll it about on a bench, using a fine parallel chain saw file with a few trurns of tape around the end enables the lip to be removed with precison. The ridge remover tools require great care and can easily extend into the worn area. Also operate at a comsiderable taper giving a larger top land clearance than necessary, esp on other makes.
