Sensor Plate Inspection; Rear Oil Seal Inspection; Flywheel Inspection; Cylinder Block Inspection - Suzuki SX4 Service Manual

1D-68 Engine Mechanical:

Sensor Plate Inspection

Check sensor plate for crack damage.
If malcondition is found, replace it.

Rear Oil Seal Inspection

Carefully inspect oil seal (1) for wear or damage. If its lip
is worn or damaged, replace it.

Flywheel Inspection

Visual Inspection
• If ring gear is damaged, cracked or worn, replace
flywheel.
• If the surface contacting clutch disc is damaged, or
excessively worn, replace flywheel.
Flywheel Face Runout
Check flywheel face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Flywheel face runout
Limit: 0.2 mm (0.0079 in.)

Cylinder Block Inspection

S7RW0A1406040
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.
Oversize piston specification
Oversize 0.50: 78.453 – 78.468 mm (3.0887 –
3.0893 in.)
3) Using micrometer, measure piston diameter.

Measurement position for piston diameter
"a": 19.5 mm (0.77 in.)
S7RW0A1406042
4) Rebore and hone cylinder to the following
dimension.
NOTE
Before reboring, install all main bearing caps
in place and tighten to specification to avoid
distortion of bearing bores.
Cylinder bore diameter to be rebored
Oversize 0.50: 78.500 – 78.514 mm (3.0906 –
3.0911 in.)
5) Measure piston clearance after honing.
Piston clearance
0.032 – 0.061 mm (0.0013 – 0.0024 in.)
