CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
-
Install connecting rod bearings (2) to connecting rod (3) and cap, and tighten connecting rod bolts to the specified torque. Refer to See: Service
and Repair/Disassembly And Assembly for tightening procedure.
1 : Connecting rod bearing cap
A : Example
B : Inner diameter measuring direction
-
Measure the inner diameter of connecting rod bearing with an inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) - (Crankshaft pin journal diameter)
Standard and Limit : Refer to See: Connecting Rod Bearing/Specifications
-
If clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end diameter and crankshaft pin journal
diameter to obtain specified bearing oil clearance. Refer to See: Connecting Rod Bearing/Service and Repair.
Method of Using Plastigage
-
Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
-
Cut a Plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
-
Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified torque. Refer to See: Service and
Repair/Disassembly And Assembly for the tightening procedure.
CAUTION:
Never rotate crankshaft.
