Service Manual

Injection Pump Pressure and Delivery Rate

Injection pump pressure and the delivery rate of the

mp, 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.
