Cylinder head assemblies: checks and adjustments
Remove the oil cooler from the
frame
Remove the valve covers
Remove the horizontal cylinder
exhaust pipe
Remove the timing belt covers
Note
Engine timing should be checked after changing parts such as camshafts, valves or timing belt rollers or when overhauling
badly worn engines.
Remove the spark plugs and install the tool (E) 88765.1297 in the spark plug recess to determine the piston's TDC,
along with gauges (C) 88765.1581 and the timing check tool with timing degree wheel (G) 88713.0123.
Reset the opening valve clearance when the camshaft is in rest position by inserting a feeler gauge between the opening
rocker arm and the opening shim.
Check that in this condition the camshaft can rotate. If it moves stiffly, use a thinner feeler gauge.
In this condition, with the piston of the horizontal cylinder at TDC and the valves fully closed as confirmed by the reading
on dial gauge (E), set gauges (C) to zero.
Set the tension value of the belts as described at Sect. 9 - 4.2,
Turn the degree wheel (G) counter clockwise until the gauge dial (C), on the exhaust side, shows a lift of 1 mm. Check
that the value of the angular displacement read on the degree wheel (G) is as specified in (Sect. 3 - 1.1,
system/valves).
Continue to rotate in the same direction until you obtain a lift of 1 mm on the intake side. Check the angular value on the
degree wheel.
Continue to rotate until, in correspondence with the closure of the valve for the compression stroke, you obtain a lift of the
