REASSEMBLY
Refer to the Exploded View and Cross Sectional View drawings on pages 8 &10.
Reassembly of any of the sub assemblies
detailed in the exploded view on page 8 is
basically in the reverse order shown. Refer
also to the following instructions:
NOSE ASSEMBLY
1. Begin by pressing the bearing (46) and seal
(45) into nose housing (44) using a press
with an appropriate pressing tool.
2. Drive home the seal (30) into the bearing
housing (34) until it bottoms.
CAUTION
Ensure the seal (30) is fitted the correct way ie
with the tapered leading edge engaged first.
Liberally grease the exposed side of the seal
(30) with lithium based grease such as
Valvoline Valplex EP grease or similar.
3. Using a press drive home the bearing (29)
into the bearing housing (34) until it
bottoms. Then insert drive shaft (39) into the
bearing (29) and press home. Ensure the
bearing housing (34) is well supported
during this operation. Finally fit circlip (28)
using circlip pliers.
4. Slip on spider hub assembly (27) onto shaft
(39) and fit circlip (22) using circlip pliers.
5. Fit o'rings (33), (35) and (42) onto bearing
housing (34).
6. Fit o'ring (36) and wiper seal (38) onto
piston (37).
7. Liberally grease piston (37), the inner
portion of the bearing housing (34) and
drive shaft (39) where it extends, then
gently slide piston (37) onto the bearing
housing (34) without damaging o'ring( 35).
8. Slide drive assembly (40) onto drive shaft
(39) and then fit spring (41) over drive
assembly (40).
9. Liberally coat the inner regions of nose
housing (44) and bearing (46) with grease
and assemble nose assembly over piston
(37) taking care not to damage wiper seal
(38). Rotate the nose assembly until the
two countersunk screw holes line up
between the nine main screw holes.
10. Squeeze together bearing housing (34)
and nose housing (44) being careful not to
damage
o'ring
countersunk screws (32).
11. Slide gear case (31) onto bearing housing
(34), ensuring o'ring (33) is not damaged
by smearing oil on the o'ring (33) to allow
gear case (31) to easily slide over.
12. Line up set screw holes and install nine set
screws (43)
13. Invert the built up nose assembly and
restrain in the vertical position. Install the
three planet gears (25) and bearings (26)
onto the spider hub assembly (27).
Coat gear bearings with grease before
assembly.
Ensure planet gears (25) are installed with the
boss side of the gear facing the spider hub
assembly (27).
14. Install retainer (24) to the spider hub
assembly
(27)
countersunk screws (23).
15. Liberally pack gear teeth with suitable
grease such as Valvoline Valplex EP or
similar.
The nose assembly is now ready to accept
the motor assembly.
