NOTE
Injection timing adjustment is accomplished by
adding or removing shims under the injection
pump.
The timing advances byremovingone shimand
retards timing by adding the same shim.
The addition or removal of 0.05 mm (0.0020in.)
of shim, changes the injection timing by approx-
imately 0.009 rad. (0.5°).
Sealant should be applied to both sides of soft
metal gasket shims except for the .0175mm
shim. A .0175mm shim should have sealant ap-
plied to one side only.
When replacing the injection pump be sure to
use the same number and size of new gasket
shims.
5.1.2 Shim Identification
Shims are available in thicknesses of 0.20 mm,
0.25 mm, 0.30 mm, and 0.35mm. Combine
