Removal
Tool
Replace the bearing sleeve
using tool 506 37 53-01.
Remove the sleeve
Fit the puller as shown in the
illustration. The puller's two
rings are used for removal.
Tighten the screw until the
sleeve is entirely out.
Assembly
Grease the tool
As the bearing sleeve is
screwed in, there is a tenden-
cy for the sleeve to rotate in
the same direction.
Minimise this by greasing
the tool's sliding surfaces.
Align the sleeve with the
thread
Fit the tool and secure the
sleeve lightly in place.
Rotate the sleeve so that
its hole lines up with the
hole* in the machine body.

Removal
Tool
In order to be able to replace the
bearing sleeve, it is necessary to use a
special tool produced by Partner.
The tool's part number is 506 37 53-01.
For removal, use the complete tool
as in the illustration.
For assembly, remove the long
intermediate ring.
Remove the sleeve
Fit the puller as shown in the illustra-
tion. The puller's two rings are used
for removal.
Tighten the screw until the sleeve
is entirely out.
Assembly
Grease the tool
As the bearing sleeve is screwed in
using the tool, there is a tendency
for the sleeve to rotate in the same
direction. (This problem is illustrated
in the next picture.)
Greasing the tool's sliding surface
minimises this tendency.
Align the sleeve with the thread
Fit the tool, see the next illustration,
and secure the sleeve in place by
hand.
Rotate the sleeve so that its hole
lines up with the hole* in the machi-
ne body.
*) Old model = stopper screw
New model = exit duct
Tighten the bearing sleeve
Tighten the bearing sleeve until it
bottoms in the chassis.
Replaceable seals
Remove the seals using a sharp tool.
The scraper consists of two parts,
an O-ring and a plastic ring. The O-
ring is fitted first and placed on the
outside (against the roller). The
plastic ring is first shaped around a
round object (1) and then fitted in
the bearing sleeve (2). Use a pair of
pliers that do not damage the sealing
surface, circlip pliers will do very well.
Shape the plastic ring and press it
into place with finger pressure.
