Crankshaft: Testing and Inspection
INSPECTION
CONNECTING ROD AND CRANKSHAFT
1. Check the connecting rod end play.
Using a feeler gauge, measure the end play while moving the connecting rod back and forth.
Standard end play : 0.1 - 0.25mm(0.004 - 0.010in.)
A. If out-of-tolerance, install a new connecting rod.
B. If still out-of-tolerance, replace the crankshaft.
2. Check the connecting rod bearing oil clearance.
(1) Check the matchmarks on the connecting rod and cap are aligned to ensure correct reassembly.
(2) Remove 2 connecting rod cap bolts.
(3) Remove the connecting rod cap and bearing half.
(4) Clean the crank pin and bearing.
(5) Place plastigage across the crank pin.
(6) Reinstall the bearing half and cap, and torque the bolts.
Tightening torque
19.6Nm (2.0kgf.m, 14.46lb-ft) + 90°
NOTE:
Do not turn the crankshaft.
(7) Remove 2 bolts, connecting rod cap and bearing half.
(8) Measure the plastigage at its widest point.
Standard oil clearance
0.038 - 0.056mm(0.0015 - 0.0022in.)
(9) If the plastigage measures too wide or too narrow, remove the upper half of the bearing, install a new, complete bearing with the same color
mark (select the color as shown in the next column), and recheck the clearance.
CAUTION:
Do not file, shim, or 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 (the color listed above or below that one), and
check clearance again.
NOTE:
If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over.
CAUTION:
If the marks are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only
