Item Standard Limit
Clearance No.1 comp- 0.15 to 0.30
between ression ring (0.0059 to 0.0118)
ends of No.2 comp- 0.15 to 0.35 1.50
piston ring ression ring (0.0059 to 0.0138) (0.0591)
Oil ring 0.20 to 0.40
(0.0079 to 0.0157)
(4)Clearance between piston pin and piston
Measure the diameter of the piston pin and the
bore in the piston for the pin as shown in the
illustration to find the clearance. If the
clearance exceeds the limit, replace the
piston or pin whichever is badly worn.
2.Connecting rods
Check the connecting rod for bend or twist as
follows:
(a)Measure”C”and”L”If”C”exceeds0.05 mm
(0.0020 in.)per 100 mm(3.94in.)of”L”straighten
the connecting rodwith a press.
Unit:mm(in.)
Item Standard Limit
Bend or twist of 0.05 / 100(0.0020 / 0.15 / 100
connecting rod 3.94)maximum (0.0059 / 3.94)
(b)Generally, a connecting rod aligner is

To check the rod for bend, install the cap to
the connecting rod and tighten the cap nuts
to the specified torque.
