Using a dial indicator, measure the thrust clearance while moving the connecting rod back and forth.

Standard thrust clearance:

0.15 to 0.40 mm (0.00591 to 0.0157 in.)


Maximum thrust clearance:

0.50 mm (0.0197 in.)


If the thrust clearance is more than the maximum, replace the connecting rod sub-assembly. If necessary, replace the crankshaft.


Hide 2.INSPECT CONNECTING ROD OIL CLEARANCE

a.

Check that the matchmarks on the connecting rod sub-assembly and connecting rod cap are aligned.

HINT:

The matchmarks on the connecting rod sub-assembly and connecting rod cap are guides for correct reassembly.



b.
