Crankshaft Thrust Play
1) 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: 2.500 mm (0.0984 in.)
Oversize (0.125 mm (0.0049 in.)): 2.563 mm
(0.1009 in.)
2) Tighten main bearing cap No.1 bolts (1) – (10) and
main bearing cap No.2 bolts (11) – (20) gradually as
follows.
a) Tighten bolts (1) – (10) to 30 N
˜
m (3.0 kg-m, 22.0
lb-ft) according to numerical order in the figure.
b) In the same manner as in Step a), tighten them
to 50 N
˜
m (5.0 kg-m, 36.5 lb-ft).
c) In the same manner as in Step a), retighten them
to 60
q
.
d) Tighten bolts (11) – (20) to 25 N
˜
m (2.5 kg-m,
18.0 lb-ft) according to numerical order in the
figure.
Tightening torque
Main bearing cap No.1 bolt ((1) – (10)): 30
N
˜
m (3.0 kg-m, 22.0 lb-ft), 50 N
˜
m (5.0 kg-m,
36.5 lb-ft) and then retighten by turning
through 60
q
Main bearing cap No.2 bolt ((11) – (20)): 25
N·m (2.5 kg-m, 18.0 lb-ft)
3) 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 referring to “Main Bearing Cap No.1
Bolt” in “Main Bearings Inspection: ”.
Out-of-Round and Taper (Uneven Wear) of Journals
An unevenly worn crankshaft journal shows up as a
difference in diameter at a cross section or along its
length (or both). This difference, if any, is determined by
taking micrometer readings. If any one of journals is
badly damaged or if amount of uneven wear in the sense
exceeds its limit, regrind or replace crankshaft.
Crankshaft out-of-round and taper
Limit: 0.01 mm (0.0004 in.)
