Piston clearance:
Measure cylinder bore diameter and piston diameter to find
their difference which is piston clearance. Piston clearance
should be within specification as given below. If it is out of
specification, rebore cylinder and use oversize piston.
Piston clearance

: 0.016 – 0.045 mm (0.0006 – 0.0018 in.) with coating
Ring groove clearance:
Before checking, piston grooves must be clean, dry and free
of carbon deposits.
Fit new piston ring (1) into piston groove, and measure clear-
ance between ring and ring land by using thickness gauge
(2). If clearance is out of limit, replace piston.
