Check piston ring grooves
for
wear
using
new
rings
and a
feeler gage
to
measure side clearance
as
shown
in Fig.
'80.
Renew piston
if
clearance exceeds
0,25
mm
(0,010 inch)
for
compression
rings
and 0.15 mm
(0,006 inch)
for oil
control ring. Check pistons
for
wear,
scratches

of
0,5 mm (0.020 inch)
or
