E. Changing piston rings
1. Remove the piston rings with piston ring pliers. Do not open
the rings more than necessary. If the rings are to be used
again ensure that they are fitted in the same groove.
2. Clean t he piston ring groove and measure the piston ring
clearance, which must not exceed 0,15 mm. Determine
whether too large a clearance is due to worn rings or a worn
groove. Change worn parts.

a time into the cylinder bore. The piston ring gap must not
exceed 1mmon 1. and 3. piston rings and 1,5 mm on 2. pis-
