Manual Extract

The Robert Bosch Model PES Multiple
Plunger Fuel Injection Pump is an extremely compact and precision unit incorporating a high pressure injection pump, a mechanical variable speed centrifugal type governor, and a positive displacement plunger type fuel transfer pump.
The function of the fuel injection pump is to deliver accurately metered quantities of fuel under high pressure to the fuel injectors.

This delivery must be accomplished with accurate timing in relation to the engine firing order and for a very definite period of time in relation to load and engine speed requirements.
To meet these rigid requirements, the model PES Injection Pump is manufactured to unusually close tolerances. While the pump cannot be considered delicate, the precision with which it is manufactured can be compared to that of a fine watch.
It is therefore doubly important that you take extra precautions to prevent the entry of dust or similar abrasives when you perform service work that involves the fuel injection pump or other components of the fuel system.
