The cold starting aid is connected by a shaft to the advance
lever for the timing of the fuel injection pump. The cold starting
aid and the advance lever are internal components of the
Lucas DP200 Series fuel injection pump.

The Stanadyne fuel injection pump on Type 2 engines is not a
serviceable part. The adjustment for the timing of the fuel
injection pump is made internally. The adjustment is tamper
proof. The low idle is adjustable. The adjustment for high idle
is preset at the factory. High idle should only be adjusted by
personnel with the correct training. The pump has a boost
control and an engine stop solenoid. The design of the pump
will automatically remove air from the pump.
The fuel injection pump has an electrically operated cold
starting aid which holds the timing of the pump in an advanced
position when the engine is cold. The advance lever of the
pump is enclosed within the pump housing. The cold starting
aid should only be adjusted by personnel with the correct
training.
The cold starling aid is connected by a shaft to the advance
lever for the timing of the fuel injection pump. The cold starling
aid and the advance lever are internal components of the
Stanadyne fuel injection pump.
A temperature switch is installed in the coolant passage which
is located at the rear of the timing case. The temperature
switch sends current to the electrical connection of the cold
starling aid (not shown) when the engine is started and when
the engine is below normal operating temperature. The body
contains a wire coil with high electrical resistance. The wire
coil surrounds an element which is filled with wax. The wire
coil heats the wax which then expands. The expansion of the
wax forces a rod to move the lever of the timing advance. The
lever continuously adjusts the pump to the correct timing for
the normal operating temperature.
