11. To remove the piston from the connecting rod press
the piston pin from each piston. Use the piston setting
tool (Fig. 87).
IMPORTANT: Do not attempt to remove the piston
pins by driving then out with a hammer. A stuck
piston pin, requiring excessive pressure to remove,
should be replaced.
12. Check for bending or distortion of the connecting
rod. The service limit for bend and distortion is 0.15 mm
(0.006 in.). Replace the connecting rod if damaged or
out of specification.
13. To assemble the piston to the connecting rod, press
the piston pin into the set position. Use the piston pin
setting tool (Fig. 88). Make sure the identification mark
of the rod and the arrow mark on the piston head are
directed up.
Pin press fitting force: 500 - 1500 kg (1100 - 3300 lb.)
14. Assemble each connecting rod and bearing to the
crankshaft in proper order. Use a feeler gauge to meas ­
ure the side clearance between the connecting rod end
and crankshaft (Fig. 89). Replace the connecting rod
assembly if the side clearance is more than the specified
amount.
Maximum connecting rod side clearance: 0.5 mm (0.02 in.)
