Inspection:
Bearing housing (1) and gearbox internals
can be inspected by removal of the gear
cover (11). Before removing the gear cover
(11) for inspection it is advisable to
purchase, a new gearbox gasket (9) and two
gearcover screw seals (4 screws on LH72,
74, 76) (19). Then proceed as follows:
a) Disconnect pump from drive and remove
shaft coupling.
b) Drain lubricating oil from pump gearbox
via drain plug (14).
c) Remove two gear cover securing screws
(18) and plastic sealing washers (19).
(4 screws on 7 Size)
d) Remove drive shaft key (29) and
gearcover (11), taking care not to damage
the drive shaft oil seal on the drive shaft
key-way.
e) Preliminary inspection can now be carried
out without further dismantling. e.g.
condition of timing gears or movement in the
bearings.
f) If all is found to be satisfactory, refit in
reverse order using new gasket (9) & seals
(19).
Repair:
To repair the bearing housing assembly you
will need the parts contained within the
appropriate Repair Kit (k), in addition to any
new gears (6) or bearings (4 & 5) required,
which should be purchased before
commencing.

BEARINGS
If the shafts are to be removed for any
reason, label all components including
bearing outer races, shims etc. and keep in
their correct positions.
With the pump disconnected from its drive,
remove rotorcase (see section 6.10), drain
oil via plug (14) and remove gear cover (11),
bend down the tab washers (7) which lock
the gearnuts (8).
Before loosening the gearnuts (8) lock the
rotors on the shaft using the plastic block
supplied for this purpose. Loosen the
gearnuts (8) using a C-spanner.
Remove gearnuts (8), tab washers (7),
timing gears (6) and drive shaft keys (28),
from the shafts.
For LH32 and LH34 models:
Remove gearnuts (8), tab washers (7),
timing gears (6) and drive shaft keys (28),
from the shaft.
Using a C-spanner loosen and remove the
bearing nuts and tab washers from the
shafts.
Using a light press or soft hammer, drive out
the shafts (24 & 25) towards the front
(rotorcase end) of the bearing housing (1)
(See figure 21). This will push out the front
oil seals (23).
