Adjusting Engine Valves
Verify each 1000 hours
VALVE CLEARANCE
Adjust the clearance between the rockers and valves
using a Allen tools kit (1), a wrench tool (3) and a feeler
gauge (2).
Always adjust the valve clearance with engine cold, that
is, with engine coolant temperature below 140ºF (60°C).
First determine the top dead center (TDC) on engine nº 1
cylinder. To perform so, rotate the crankshaft slowly, using
the adapter and gear of the manual rotating tool. Install
the synchronizing pin and adjust the following valves: 1A,
1E, 2A, 3E, 4A, 5E. Remove the synchronizing pin, rotate
the crankshaft 360° and install again the synchronizing
pin. Perform the adjustment of the following valves: 2E,
3A, 4E, 5A, 6A, 6E. Clearance of valves must meet the
specications of table below
Valve clearance with engine cold:
Intake ........................ 0.20 – 0.30 mm (0.008 – 0.012 in)
Exhaust ..................... 0.46 – 0.56 mm (0.018 – 0.022 in)
NOTE: The clearance will be correct when the feeler gau-
ge is passed between the valve rod and the rocker, with
a little resistance.
