Crankshaft Inspection

S5JB0B1406038

Thrust Bearing General Information
Service thrust bearing has 4 kinds of bearings differing in 
tolerance.

Crankshaft Thrust Play

1) Install main bearings, thrust bearings, crankshaft 

and bearing caps, and tighten main bearing cap 
bolts referring to “Main Bearing, Crankshaft and 
Cylinder Block Removal and Installation”.

Thickness of crankshaft thrust bearing
• 2.30 mm (0.0906 in.)
• 2.35 mm (0.0925 in.)
• 2.40 mm (0.0945 in.)
• 2.45 mm (0.0965 in.)

2) Use a dial gauge, to read displacement in axial 

(thrust) direction of crankshaft.
If it is out of specification, replace new thrust bearing 
and recheck.

Crankshaft thrust play
0.067 – 0.233 mm (0.00264 – 0.00917 in.)

Main Bearings Inspection

S5JB0B1406039

General Information
• Upper half of bearing (1) has oil groove (2) as shown 

in the figure.
Install this half with oil groove to cylinder block.

• Lower half of bearing does not have an oil groove.

Visual Inspection
Check bearings for pitting, scratches, wear or damage. 
If any malcondition is found, replace both upper and 
lower halves. Never replace either half without replacing 
the other half.

Main Bearing Clearance

NOTE
Do not rotate crankshaft while gauging 
plastic is installed.

 

Check clearance by using gauging plastic according to 
the following procedure.

1) Remove bearing caps.
2) Clean bearings and main journals.
3) Place a piece of gauging plastic (1) the full width of 

bearing (parallel to crankshaft) on journal, avoiding 
oil hole.
