CAUTION:
 Make sure that there is no gap in the thrust surface (A) of
the joint between connecting rod (1) and connecting rod
bearing cap (2) and that these parts are in the correct
position. And then, tighten the connecting rod bolts.
 If the connecting rod bolts are reused, measure the outer
diameter. Refer to EM-219, "
Inspection After Disassem-
bly".
24. Apply new engine oil to the threads and seats of connecting rod
bolts.
25. Tighten bolts in three steps
 After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.
 Check the connecting rod side clearance. Refer to EM-219, "

shaft arm with a feeler gauge (A).
 If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crankshaft
also.
