Service Manual

11. To remove the piston from the connecting rod press

the piston pin from each piston. Use the piston setting

ool (Fig. 87).

IMPORTANT: Do not attempt to remove the piston

s 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

d. 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

he 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.)
