Ensure that the coupling guard is in place
before starting the drive.
The ISO drive coupling is a safety compo-
nent of the EPS 610. The ISO drive coupling
may only be repaired only by Bosch service
technicians.
The drive system consists of a motor (Fig. 2, Pos. 1),
flywheel (Fig. 2, Pos. 2) and coupling. The clamping po-
sition for small injection pumps can be altered with the
additional intermediate flange (special accessory).
i
The flywheel is directly mounted on the motor shaft.
The scale on the flywheel is used to set the "start of
delivery" position of the cylinders in a multi-cylinder
fuel injection pump.
i
The cam on the fuel injection pump camshaft moves
the piston of the barrel and valve assembly upwards
via the roller tappet. The "start of delivery" position
is attained when the piston closes the inlet bore.
i
The axis of the flywheel is set at 125 +/- 0.1 mm from
the top of the pump mounting bed.
The drive motor is mounted on the test pump mounting
bed. The complete test pump mounting bed assembly
is mounted on the frame. During calibration, the drive
coupling is connected to the coupling of the fuel injec-
tion pump. The drive coupling is covered with a cou-
pling guard (Fig. 2, Pos. 3).

dem pump (Fig. 8, Pos. 1). The frame has adequate
reinforcements to withstand the dynamic loads on the
bench.
