Rear Oil Seal Inspection
S3RH0A1406050
Carefully inspect oil seal (1) for wear or damage.
If its lip is worn or damaged, replace it.
For oil seal installation, press-fit rear oil seal (1) to oil
seal housing (2) by using special tool as shown in the
figure.
Special tool
(A): 09911–97820
Crank rear oil seal installing position (dimension)
“a”: 3 mm (0.12 in.)
Flywheel Inspection
S3RH0A1406051
• If ring gear is damaged, cracked or worn, replace
flywheel.
• If the surface contacting clutch disc is damaged, or
excessively worn, replace flywheel.
• Check flywheel for face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Flywheel runout
Limit: 0.2 mm (0.0079 in.)
Cylinder Block Inspection
S3RH0A1406052
Distortion of Gasketed Surface
• Using straightedge and thickness gauge, check
gasketed surface for distortion and, if flatness
exceeds its limit, correct It.
Cylinder block flatness
Limit: 0.05 mm (0.0020 in.)
Honing or Reboring Cylinders
1) When any cylinder needs reboring, all other
cylinders must also be rebored at the same time.
2) Select oversized piston according to amount of
cylinder wear.
Oversize piston specification
3) Using micrometer, measure piston diameter.
Measurement position for piston diameter
“a”: 19.5 mm (0.77 in.)
4) Calculate cylinder bore diameter to be rebored as
follows.
D = A + B – C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 – 0.04 mm (0.0008 –
0.0016 in.)
C: Allowance for honing = 0.02 mm (0.0008 in.)
5) Rebore and hone cylinder to calculated dimension.
NOTE
Before reboring, install all main bearing caps
in place and tighten to specification to avoid
distortion of bearing bores.
6) Measure piston clearance after honing.
