Main Bearing Clearance Inspection
1. Remove the main caps and bearing halves
(see page 7-13).
2. Clean each main journal and bearing half w i t h a
clean shop t o w e l .
3. Place one strip of plastigage across each main
journal.
NOTE: If the engine is still in the vehicle w h e n y o u
bolt the main cap d o w n to check the clearance, the
w e i g h t of the crankshaft and drive plate will flatten
the plastigage further than just the torque on the
cap bolt, and give y o u an incorrect reading. For an
accurate reading, support the crank w i t h a jack
under the counterweights, and check only one
bearing at a t i m e .
4. Reinstall the bearings and caps, then torque the
bearing cap bolts to 74 N-m (7.5 kgf-m, 54 Ibf-ft),
and the bearing cap side bolts to 49 N-m (5.0 kgf-m,
36 Ibf-ft) in the proper sequence (see step 21 on
page 7-26).
NOTE: Do not rotate the crankshaft during
inspection.
5. Remove the cap and bearing half, and measure the
w i d e s t part of the plastigage.
Main Bearing-to-Journal Oil Clearance
Standard (New): 0.020—0.044 mm
(0.0008-0.0017 in.)
Service Limit: 0.050 mm (0.0020 in.)
6. If the plastigage measures too w i d e or too narrow,
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing w i t h
the same color code, and recheck the clearance. Do
not file, s h i m , or scrape the bearings or the caps to
adjust clearance.
7. 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
again. If the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.
