Remove the screws (1) and disconnect camshaft (3) retaining
plate (2).
Withdraw carefully the camshaft (1) from the engine block.
Withdraw the tappets (1) from the engine block.
Once engine is disassembled, clean
accurately the
cylinder-block assembly.
Use the proper rings to handle the cylinder unit.
The engine block shall not show cracks.
Check operating plug conditions and replace them in case of
uncertain seal or if rusted.
Inspect cylinder barrel surfaces; they shall be free from seizing,
scores, ovalisation, taper or excessive wear.
Inspection of cylinder barrel bore to check ovalisation, taper
and wear shall be performed using the bore dial gauge
99395687 (1) fitted with the dial gauge previously set to zero
on the ring gauge (2) of the cylinder barrel diameter.
Measurements shall be performed on each cylinder, at three
different heights in the barrel and on two planes
perpendicular with each other: one parallel to the
longitudinal axis of the engine (A), and the other
perpendicular (B). Maximum wear is usually found on plane
(B) in correspondence with the first measurement.
Should ovalisation, taper or wear be found, bore and grind
the cylinder barrels. Cylinder barrel regrinding shall be
performed according to the spare piston diameter oversized
by 0.4 mm and to the specified assembling clearance.
Take note of plate (2) assembling position.
