INSPECTION
CYLINDER
Inspect the cylinder bore for scratch or wear.
Measure the cylinder I.D. at three levels in an X and
Y axis.
Take the maximum reading to determine the cylin-
der wear.
SERVICE LIMIT: 92.10 mm (3.626 in)
Calculate the cylinder-to-piston clearance.
Refer to page 9-4 for measurement of the piston
O.D.
SERVICE LIMIT: 0.10 mm (0.004 in)
Calculate the cylinder taper and out-of-round at
three levels in an X and Y axis. Take the maximum
reading to determine the taper and out-of-round.
SERVICE LIMITS: Taper: 0.10 mm (0.004 in)
Out-of-round: 0.10 mm (0.004 in)
The cylinder must be rebored and an oversize pis-
ton fitted if the service limits are exceeded.
The 0.25 mm (0.010 in) and 0.50 mm (0.020 in) over-
size pistons are available.
The cylinder must be rebored so that the clearance
for an oversize piston is 0.015--0.045 mm (0.0006--
0.0018 in).
Check the top of the cylinder for warpage with a
straight edge and feeler gauge across the studs and
bolt holes as shown.
SERVICE LIMIT: 0.10 mm (0.004 in)
PISTON/PISTON RING
Inspect the piston rings for movement by rotating
the rings. The rings should be able to move in their
grooves without catching.
Push the ring until the outer surface of the piston
ring is nearly flush with the piston and measure the
ring-to-ring groove clearance.
SERVICE LIMITS:Top/Second: 0.09 mm (0.004 in)
