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-.

Electric rear-wheel drive EIP220 and all-wheel drive EIA200, EIP220 - Edition 11.2021
– 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.

•
– Secure anti-twist protection -A- hand-tight to three-phase
current drive using bolts of cover -arrows- as shown in illus‐
tration.
– To loosen bus bar bolts, push retaining plates -B- towards
right, and screw in bolts -C- hand-tight.

– Screw in bolts -E- hand-tight against bolt heads -2-.
The aid of an additional mechanic is required for the subse‐
quent work steps.
NOTICE
Risk of damage to electrical connector.
– Before pulling off the power and control electronics, have
a second mechanic release and hold the connector lock
-arrow-.
– Release connector lock -arrow-, and hold it in place.
– With connector lock released -arrow-, screw in bolts -E-
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-.
– Coat new connecting piece -2- with lithium grease, and fit it
into power and control electronics -1-.
