1. |
Remove the cylinder head, timing belt, front
case, flywheel, pistons and
crankshaft. |
2. |
Remove the oil pressure switch.

CYLINDER BLOCK
1. |
Check the engine block for scores, rust and
corrosion. Also check for cracks or any other defects. Replace the
block if defective. |
2. |
Using a straight edge and feeler gauge, check
the top surface of the block for warpage. Make sure that the surface
is free from gasket chips or other foreign material.
Standard : 0.03 mm (0.0012 in.) or
less
Limit : 0.05 mm (0.0020 in.) or
less
|

|
3. |
Measure the cylinder bore with a cylinder
gauge at three levels. If the cylinder bores show more than the
specified out-of round or taper, or if the cylinder walls are badly
scuffed or scored, the cylinder block should be rebored and honed.
Now oversize pistons and rings must be fitted. The value of
measuring points are as shown.
Cylinder I.D : 82 mm (3.228
in.)
Cylinder I.D taper : 0.01 mm (0.0004
in.) or less
|

|
4. |
If a cylinder ridge exists, cut away with a
ridge reamer. |
5. |
Oversize pistons are available in four
sizes.
Piston service
size and mark mm (in.)
0.25 (0.010) O.S. : 0.25
0.50 (0.020) O.S. :
0.50
| |
6. |
When boring the cylinder bore to the oversize,
maintain the specified clearance between the oversize piston and the
bore, and make sure that all pistons used are the same
oversize. |
7. |
The standard measurment of the piston outside
diameter is taken 47 mm (1.85 in.) from the top land of the
piston.
Piston-to-cylinder clearance (To set limits to new
parts)
0.02 - 0.04 mm (0.0008 - 0.0016
in.)
