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.)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 –

Engine Lubrication System
General Description
Engine Lubrication DescriptionS6RW0D1501001
The oil pump is of a trochoid type, and mounted on the crankshaft. Oil is drawn up through the oil pump strainer and
passed through the pump to the oil filter.
The filtered oil flows into two paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. Oil from the crankshaft journal bearings is supplied to the
connecting rod bearings by means of intersecting passages drilled in the crankshaft, and then injected from the big
end of connecting rod to lubricate piston, rings and cylinder wall.
In the other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through the
internal oil way of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
specified pressure.
