Crankshaft, Main Bearings and Flywheel
CHECK MAIN BEARING OIL CLEARANCE

NOTE: The use of PLASTIGAGE will determine wear
(crankshaft-to-bearing oil clearance) but will not
determine condition of either bearing or journal
surface.
1. Place a strip of PLASTIGAGE in the center of the
main bearing cap (with insert) about three-fourths of
the width of the bearing or on crankshaft journal to
measure oil clearance.
2. Use clean (SAE30) oil on PLASTIGAGE to prevent
smearing.
3. Install cap and tighten cap screws to 135 Nm (100
lb-ft).
4. Remove cap and compare width of PLASTIGAGE
with scale provided on wrapper to determine clearance.
