CYLINDER BLOCK
The cylinder block is linerless type. When the bore is
worn so as engine performance is affected, a service liner
can be fitted.
INSPECTION
1. Check the cylinder block for cracks, scores, rust and
any other defects.
2. Measure the cylinder bore with the cylinder gauge
at the three levels at thrust side and non- thrust side.
(Fig.O.2 & 3)
Level 1: No 1 piston ring position at TDC
Level 2: Centre of cylinder
Level 3: Bottom of cylinder
3. If the cylinder bore show more than specified out-
of-round, taper, worn, badly scuffed or scored, a
service liner should be used.
Standard Cylinder Bore Size:
95.00/95.02 mm (3.740/ 3.741 inch)
4. Maintain the specified clearance between the piston
and cylinder bore, and ensure that all pistons used
are of the standard size.
5. Check the top surface of the cylinder block for
flatness. If the top surface exceeds flatness limits,
surface to minimum limit or replace.
Flatness limit: 0.01 mm (0.0004 in.)
