Injection Timing (Continued)
• 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.), 0.35 mm (0.014 in.) and
0.175 mm (0.00689 in.). Combine these shims for
adjustments.
• Addition or reduction of shim (0.025 mm, 0.00098 in.) delays
or advances the injection timing by approx. 0.0044 rad
(0.25 °).
• 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 (0.00689 in.) thick shim is coated only on the
lower face. Therefore, do not use the 0.175 mm (0.00689 in.)
thick shim as the top shim of the combination (injection
pump side), because this can cause oil leakage.
• Refer to figure of the shim to check the thickness of the
shims.
• The injection timing might be changed by the application.
