Frame

The frame supports the drive system, MGT as-
sembly (Fig. 1, Pos. 1), electrical control cabinet
(Fig. 1, Pos. 3), test oil tank (Fig. 12, Pos. 4), tandem
pump (Fig. 12, Pos. 3), heat exchanger (Fig. 12, Pos. 2)
and pressure control valve. The frame has adequate
reinforcements to withstand the dynamic loads on the
bench. The frame has panels on all sides which can be
easily removed to enable maintenance.
i
Do not place any heavy components (for ex., tool crib)
on the frame or in the oil sump below the drive motor.

Measuring glass carrier

The Measuring glass carrier (Fig 1, Pos 1) comprises
of the measuring glasses installed in a steel hous-
ing. The MGT assembly is mounted on a swivel arm
(Fig. 1, Pos. 21). The measuring glasses are reinforced
to the swivel frame by the
knob, (Fig 5, Pos 1), the swivel frame can be rotated
to empty the measuring glasses and also to change
over from 44 cc measuring glasses to 260 cc measuring
glasses. A cam plate (Fig 5, Pos 2) limits the movement
of the swivel frame.

Warning - Breakage of measuring glass
tubes
The measuring glass tubes will break if they
hit against hard objects (for eg., fixtures for
the fuel injection pump).
¶
Ensure that the measuring glass tubes
do not hit against any hard objects.
¶
Replace broken measuring glass imme-
diately.
¶
Wear protective gloves.
During calibration of the fuel injection pump, the test oil
can be collected by orienting the measuring glasses in a
tilted position. The delivery quantity can be measured by
orienting the measuring glass tubes in a vertical position.
