Crankshaft: Testing and Inspection
CONNECTING ROD AND CRANKSHAFT
1. Check the connecting rod end play.
Using feeler gauge, measure the end play while moving the connecting rod back and forth.
^
If out-of-tolerance, install a new connecting rod.
^
If still out-of-tolerance, replace the crankshaft.
2. Check the connecting rod bearing oil clearance.
1) Check the match marks on the connecting rod and cap are aligned to ensure correct reassembly.
2) Remove the 2 connecting rod cap nuts.
3) Remove the connecting rod cap and lower bearing.
4) Clean the crankshaft pin journal and bearing.
5) Place a plastigage across the crankshaft pin journal.
6) Reinstall the lower bearing and cap, and tighten the nuts.
Tightening torque: 31.4 - 34.3 Nm (3.2 - 3.5 kgf.m, 23.1 - 25.3 ft. lbs.)
NOTE: Do not turn the crankshaft
7) Remove the 2 nuts, connecting rod cap and lower bearing.
8) Measure the plastigage at its widest point.
9) If the plastigage measures too wide or too narrow, remove the upper and lower bearing and then install a new bearings with the same color
mark.
Recheck the oil clearance.
CAUTION: Do not file, shim, of scrape the bearings or the caps to adjust clearance.
10) If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing.
Recheck the oil clearance.
