Kubota WSM 05-E4B Series User Manual

6. Check
and read the timing line (2) of flywheel that
matches the alignment mark (3).
NOTE
• The flywheel has
mark "[1TC]", "[10]" and
"[20]" for the crank angle before the top
dead center of No. 1 cylinder.
(2) Timing line (3) Alignment mark
7. If injection timing is out of adjustment, readjust the
timing with shims.
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.), 0.35 mm (0.014 in.) and 0.175 mm
(0.00689 in.).
Combine these shims for adjustments.
• Addition or reduction of a shim (0.050 mm,
0.0020 in.) delays or advances the injection
timing by approx. 0.0087 rad (0.5°).
• During 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 the figure of the shim to check the
thicknesses of the shims.
• The injection timing might be changed by
the application.
