Maintenance
After removing the protective shipping materials, handle the new
pump module with care.
Before installing a new pump module, remove the four tie rods from the
new module and insert them in the old one for protection during shipment.
Remounting the Pump Module
When installing a new pump module, it is also advisable to use a new gas-
ket (14/4).
Check the coupling element (14/5) for damage; if necessary, install a new
one.
Use the tie rods supplied with the new pump module only if the old ones
are damaged. To do so, unscrew the old tie rods with lock nuts, and screw
in the new ones. With the aid of the lock nuts, tighten the tie rods. Then
remove the lock nuts.
Before installing the pump module, please check wether the washer (14/3)
is correctly seated in its opening.
Push the gasket (14/4) onto the tie rods (14/6), push the coupling element
(14/5) onto one coupling half.
Push the entire pump module (new or repaired) onto the tie rods.
Screw on the hex. nuts (14/1) and carefully cross-tighten them (torque 7.5
Nm).
Mount the oil case together with the gasket (see Chapter 5.6).
Fill in oil.
