MAINTENANCE
Technical Manual 2006
• Locate bolt (17), then spring (16) in the
axle and screw in grub screw (15) until
it is flush with the axle.
• Reclamp axle. Fit large sun gear (13) (it
is the same both sides). Position conical
compression spring (19), with the large
diameter first. Press spring together and
fit washer (20) and retaining washer (21).
• Assemble cover (22), compression
spring with 7 turns (23) and the second
cover (24, insides to the spring).
• Compress spring and position thrust
block (25) (it is the same both sides) in
the center of the slotted hole.
• Position coupling gear (26) with carrier
plate facing downwards.
• Fit cover (29, inside to the spring) for
compression spring.
• Position gear ring (27) over the teeth of
the coupling gear.
• Place ball retainer (31), with balls below
on the gear ring.
• Position large compression spring (28)
on gear ring.
• Mount compression spring with 13 turns
(30) on the axle. (Is supported in the
coupling wheel by the cover).
• Locate driver (32), press it down and
screw on fixed cone (33) as far as the
stop. Tightening torque 20 Nm.
• Clamp other axle end.
• Push on thrust washer (11) and fit
planetary gear carrier (10). In doing this:
Position mounting aid
(Fig. 2) on the
planetary gear carrier so that the (X)
markings on the three planetary gears
match with the mounting aid.
• Insert planetary gear carrier, place
thrust washer (8) on it and mount
retaining washer (9) in recess.
Now remove the mounting aid.
Advice:
If the gears are not accurately installed
the hub may be tight to move.
This could lead to damage to the gear-
wheels in operation.
• Assemble hub shell (6) with a slight
counter-clockwise movement.
In case the hub shell jams, position the
plastic ring
(Fig. 3) correctly.
• Screw brake cone (7) clockwise onto the
planetary gear carrier (10) until it stops.
• Insert 3 brake segments (5).
• Turn in friction spring (3) counterclock-
wise into the lever cone (2) (inlying
winding of the spring has to lie against
the lever cone)
(Fig. 4) .
• Insert ball retainer (4) (balls are facing
upwards) into lever cone (2): the 3 re-
cesses have to engage into the retaining
lugs of the lever cone. Slightly turn ball
retainer to prevent it from falling off.
• Fit lever cone onto hub shell: the retain-
ing lugs of the lever cone have to en-
gage into the openings between the
brake segments. Make sure that lever
cone engages while turning back and
forth slightly.
• Screw on locknuts (1), adjust bearing
so that there is no play and lock nuts
together with 15 – 20 Nm (133 – 177in.lbs.).
Caution:
Check that all the brake system
components are functioning properly!
Advice:
Dismantling and reassembly of hub types
with drum brake (MH 5225 Cargo) should
be carried out in the same way.
Differences: Instead of brake segments /
cone a click-and-pawl carrier is installed
on the planetary gear carrier.
