CYLINDER BLOCK
Revision: 2006 November2007 350Z
If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer
to EM-120, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage
Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
Cut 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 speci-
fied torque. Refer to E M - 111 , "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
Remove connecting rod bearing cap and bearing, and using
scale on plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
Install main bearings (3) to cylinder block (1) and lower cylinder
block (2), and tighten lower cylinder block bolts to the specified
torque. Refer to EM-111, "
ASSEMBLY" for the tightening proce-
dure.
Measure the inner diameter of main bearing with bore gauge.
(Bearing clearance) = (Main bearing inner diameter) – (Crankshaft
main journal diameter)
If the clearance exceeds the limit, select proper main bearing according to main bearing inner diameter
and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-122,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage
Remove oil and dust on crankshaft main journal and the surfaces of each bearing completely.
Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
Install main bearings to cylinder block and lower cylinder block, and tighten lower cylinder block bolts with
lower cylinder block to the specified torque. Refer to E M - 111 , "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
