Adjusting the fuel injection timing
(a)
If the fuel injection timing does not conform to
above specified BTDC, adjust the shim
thickness under the fuel injection pump
housing. Changing the shim thickness by 0.1
mm (0.004 in.) will change the fuel injection
timing by approx. 1°
(b)
Increasing the shim thickness will retard the
fuel injection timing. Reducing the shim
thickness will advance the fuel injection
timing.
Adjustment range
Standard value ±1.5º
Shims are available in thicknesses of 0.2 mm
(0.008 in.), 0.3 mm (0.012 in.), 0.4 mm (0.016
in.) and 0.8 mm (0.031 in.). Thicknesses are
not indicated on shims. Measure the thickness
of the shim being used with a pair of vernier
calipers or other similar tool to confirm the
thickness.
Apply sealant to both sides of the shim to
prevent oil leakage.
(c)
Verify the fuel injection timing after
adjustment.
(d)
Close the fuel filter cock. Install the delivery
valve spring and the fuel injection pipe.
