4.5 Clamping the common rail pump
!
Always observe the tightening torques of fastening
parts and coupling halves (see sec. 8, Tightening
torques).
!
The T-bar (special accessory) used to manually
rotate the flywheel (fig. 8, pos. 1) must not be left
inserted in the locating holes of the flywheel.
!
The drive coupling (fig. 8, pos. 2) is a safety
component of the EPS 708. The drive coupling may
therefore only be repaired by the responsible Bosch
Customer Service.
!
During all assembly work, such as clamping/
removing common rail pumps and common rail
injectors, the protective hood of the EPS 708 must
always be opened as far as it will go.
!
Only use the specified clamping devices and drive
couplings for clamping common rail pumps on the
EPS 708.
!
Before mounting the common rail pump to the
EPS 708, check actuators (EAV, DRV, DMV or ZME)
for short-circuited turns. If the resistance between
the connection pin and the housing is lower than
50 Ohm, then the defective actuator must be
replaced before mounting to the EPS 708.
!
Before clamping a common rail pump on the
EPS 708, check the pump housing for cracks and
the freedom of movement of the pump drive shaft.
Common rail pumps with a stiff or jammed drive
shaft or with a cracked housing must not to be
clamped or tested.
!
Before fitting the drive flange, lubricate the radial
shaft oil seal of the common rail pump with engine
oil 15W-40. The common rail pump is only to be
operated with a lubricated radial shaft oil seal.
i
When testing common rail pumps without a
lubricating oil supply, the lubricating oil supply and
return pipes (fig. 2, pos. 1 and 2) must be sealed
with dummy plugs.
i
All clamping components and couplings required for
clamping are contained in the special accessories
catalog for EFEP/EPS (part number 1 689 980 289)
or on the ToolsCATAlogue special accessories CD.

1. Secure the drive coupling 1 686 401 024 (fig. 8,
pos. 2) to the flywheel (fig. 8, pos. 1) of the
EPS 708. The tightening torque of the bolts is
95 ±2 Nm.
2. In the CP 3.4 with lubricating oil supply, insert the
O-ring Ø10 x 3 mm (fig. 9, pos. 1) in the lubricating
oil supply hole of the common rail pump.
