Crankshaft Inspection
S3RH0A1406041
Runout
Using a dial gauge, measure runout at center journal.
Rotate crankshaft slowly. If runout exceeds its limit,
replace crankshaft.
Crankshaft runout
Limit: 0.04 mm (0.0016 in.)
Thrust Play
Measure this play with crankshaft set in cylinder block in
the normal manner, that is with thrust bearing (1) and
journal bearing caps installed.
Thickness of crankshaft thrust bearing
Standard: 2.470 – 2.520 mm (0.0973 – 0.0992 in.)
Oversize (0.125 mm (0.0049 in.)): 2.533 – 2.583 mm
(0.0998 – 0.1016 in.)
Tighten bearing cap No.1 bolts (1) – (10) and No.2 bolts
(11) – (20) gradually as follows.
1) Tighten bolts (1) – (10) to 30 N
⋅
m (3.0 kgf-m, 22.0 lb-
ft) according to numerical order in the figure.
2) In the same manner as in Step 1), tighten them to 50
N
⋅
m (5.0 kgf-m, 36.5 lb-ft).
3) In the same manner as in Step 1), retighten them to
60
°
.
4) Tighten bolts (11) – (20) to 22 N
⋅
m (2.2 kgf-m, 16.0
lb-ft) according to numerical order in the figure.
Tightening torque
Crankshaft bearing cap No.1 bolt ((1) – (10)):
Tighten 30 N
⋅
m (3.0 kgf-m, 22.0 lb-ft), 50 N
⋅
m (5.0 kgf-
m, 36.5 lb-ft) and 60
°
by the specified procedure
Crankshaft bearing cap No.2 bolt ((11) – (20)):
Tighten 22 N
⋅
m (2.2 kgf-m, 16.0 lb-ft) by the specified
procedure
Use a dial gauge to read displacement in axial (thrust)
direction of crankshaft.
If its limit is exceeded, replace thrust bearing with new
standard one or oversize one to obtain standard thrust
play.
Crankshaft thrust play
Standard: 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit: 0.35 mm (0.0138 in.)
NOTE
After checking the thrust play, make sure that
thread deformation of each bearing cap No.1
bolt according to “Bearing Cap Bolt” under
“Main Bearings Inspection”.
