Calculate the piston-to-piston pin clearance.
SERVICE LIMIT: 0.04 mm (0.0016 in)
Measure the connecting rod small end I.D.
SERVICE LIMIT: 15.09 mm (0.594 in)
Calculate the connecting rod small end-to-piston pin clear-
ance.
SERVICE LIMIT: 0.075 mm (0.0030 in)
NOTE:
Always replace the piston rings as a set.
Inspect the piston ring, and replace them if they are worn.
Temporarily install the piston rings (page 11-7) into the
piston grooves.
Push in the ring until the outer surface of the piston ring is
nearly flush with the piston and measure the clearance
using a feeler gauge.
SERVICE LIMIT:
Top: 0.10 mm (0.00s in)
Second: 0.08 mm (0.03 in)
Using a piston, push the ring securely into the cylinder
and measure the end gap using a feeler gauge.
SERVICE LIMIT:
Top: 0.3 mm (0.01 in)
Second: 0.7 mm (0.03 in)
