Static Injection Lead Test On Flywheel - Kohler KD225 Workshop Manual

115
Use a temporary tank if the engine is not fitted with one. Here again, it is essential to make sure that the fuel level is no
more than 10-15 cm above the injectionm pump.
References on the flywheel
A = Reference of fixed TDC on crankcase
B = Injection lead reference on the flywheel
C = TDC reference on flywheel
α
= Reference in degrees between B and C.
When B coincides with A, the piston is in the static injection lead position. When C coincides with A, the piston is at top dead
center.

Static injection lead test on flywheel

Fill the tank and make sure that the fuel is not more than 10-15 cm
above the tester. Set the flow governor lever of the injection pump in
the stop position and lock it there.
Turn the flywheel in the engine rotation direction. proceed slowly du-
ring the compression phase. The fuel that flows from tube 2 will tend
to diminish. Stop as soon as it creases to drip (one drop of fuel every
30-40 seconds is tolerated): this is the static injection lead. Make sure
that B coincides with A.
See fig. 117-118 if B does not coincide with A.
