Injection pump
The pump does not have a separate bottom plate. The pump
body and flange are of integral design. The smoke limiter is
mounted on top of the governor housing (TAD1630P/V only).
The pressure leveling device and bypass valve are mounted
opposite each other at the front of the pump.
The injection pump carries no external markings for check-
ing the injection angle.
To check the injection angle, the lifting height must be meas-
ured with a dial indicator.
Note: Repairs requiring work in the injection pump can alter
its setting and should only be carried out by specially trained
mechanics with the required tools and testing devices at
their disposal.
All warranties on the engine are void if the seals are broken
by unqualified mechanics.
Ensure the greatest possible cleanliness when working with
the fuel system.
TWD1620G/GH, TID162AG,
TWD1630G/GE
These engines have an RQ-governor. The RQ- governor is
mechanical and works by means of speed sensitive gover-
nor flyweights. The governor is used when constant speed is
to be obtained (1500/ 1800 rpm).
TAD1630P/V, TWD1630P/V, TID162AP and
TD164KAE
The injection pump on TAD/TWD1630P/V, TID162AP and
TD164KAE is equipped with an RQV governor. The RQV-
governor is mechanical and works by means of speed sen-
sitive governor flyweights. The speed is regulated throughout
the entire speed range of the engine, from low idling to high
idling (variable speed type).
