Injection Pump Pressure and Delivery Rate
Injection pump pressure and the delivery rate of the
pump, as well as inter-cylinder delivery rates must be
determined by the use of specialized equipment. If
difficulties with the injection pump are suspected the
help of a competent diesel engine service shop should
be sought.
Injection Pump Timing and Adjustment
Adjusting the shim thicknesses as explained on, "Injec-
tion Timing Test," will adjust the injection timing.
NOTE: If timing requires adjustment, and the engine has
not been worked on, or the shim thickness changed, the
injection pump components and camshaft should be
inspected for wear or damage.
