Cylinder Block Inspection; Flywheel Inspection; Rear Oil Seal Inspection - Suzuki Liana RH418 Supplementary Service Manual

Rear Oil Seal Inspection

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.

"a": 3 mm (0.12 in.)

Flywheel Inspection

• 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

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: 0.03 mm (0.0012 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.

3) Using micrometer, measure piston diameter.

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 = 0.016 – 0.045 mm (0.0007 –
0.0017 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.
