4.4.1 Checking injection timing
NOTE
• The liquid gasket is not required for
assembling.
• Shims are available in thickness of 0.20 mm
(0.0079 in.), 0.25 mm (0.0098 in.), 0.30 mm
(0.012 in.) and 0.175 mm (0.00689 in.). Combine
these shims for adjustments.
• Addition or reduction of shim (0.05 mm,
0.002 in.) delays or advances the injection
timing by approx. 0.009 rad (0.5°).
• In disassembling and replacing the injection
pump, be sure to use the same number of new
shims with the same thickness.
• The 0.175 mm thick shim is coated only on the
lower face. Therefore, do not use the 0.175 mm
thick shim as the top shim of the combination
(injection pump side), because this can cause
oil leakage.
