What are some common clues to pump failure ?
- Engine will not run or stalls due to plugged outlet
fitting. This is typically caused by a broken governor
weight retaining flex ring.
- External leaks which cause hard starting. Typical leakage
areas are the shaft seals, advance plunger, and throttle
- Excessive smoke and poor driveability due to worn
injection pump housing. When the steel advance piston
wears out the aluminum housing, incorrect advance and
poor engine operation result.
