Removing and installing power and
control electronics for electric drive
[JX1]
Special tools and workshop equipment required
♦ anti-twist protection -T10614-
♦ puller -T10611-
The power and control electronics for electric drive -JX1- will
henceforth be referred to as “power and control electronics”.
The three-phase current drive -VX54- will henceforth be refer‐
red to as “three-phase current drive”.
Removing
– ⇒ Rep. gr. 10; Removing rear motor.
– ⇒ Rep. gr. 10; Securing motor to engine and gearbox sup‐
port, rear motor.
– Remove clamping washers -arrows- and take off noise insu‐
lation -1-.
– Unscrew centre hex studs -1- and bolts -arrows-.
– Lever off cover -1- at positions indicated by -arrows-. In the
process, make sure not to damage the sealing surfaces of
the three-phase current drive.

Note
Due to the adhesive strength of the sealant, the cover is bent
when being removed. For this reason, the cover always needs
to be renewed.
Prepare anti-twist protection -T10614- for loosening bus bar
bolts:
– Loosen bolts -C- for retaining plates -B- approx. 1 turn.
Important
It must be possible to move the retaining plates -B-.
•
– Secure anti-twist protection -A- hand-tight to three-phase
current drive using bolts of cover -arrows- as shown in illus‐
tration.

evenly, and pull off power and control electronics until con‐
tact is made with bolt heads -2-.
– Insert a plastic wedge between the power electronics and
three-phase current drive to prevent the electrical connector
from re-engaging.
– Remove puller -D-.
– Completely unscrew bolts for power and control electronics,
and remove power and control electronics.
Installing
NOTICE
Risk of soiling of three-phase current drive by sealant residue.
– Cover the exposed parts of the three-phase current drive.
– Completely remove sealant residue from all sealing surfaces
without damaging the sealing surface.
Important
•
The sealing surfaces must be free of oil and grease.
– Thoroughly clean opening for connecting piece on three-
phase current drive -arrow-.
