Injection Pump Timing Check
Rotate the engine to TDC.
Correct timing of the Lucas CAV DPA pump can be
verified by removing the inspection plate. Clean all dirt
and foreign material from around the timing window
cover on the injection pump.
NOTE: Special equipment in an authorized shop is
required to precisely time the Lucas CAV DPA
pump. However, for troubleshooting and in an
emergency, visual alignment of the timing mark is
close enough for the engine to run.
