e) Pull outer races of bearings out of the "drive" hous-
ing half using the extracting unit (Fig. 5-7c) or heat
the half of the housing in an oven to approx.
120ëC (248ëF) and remove the outer races of bear-
ings together with shims.

WARNING
|
Handle heated housing half and outer race only with
protective gloves!
NOTE.
Make sure to keep the shims with each outer race

Handle heated housing only with protective gloves!
b) Insert the required shims for proper pretension into
bearings bore under bearing outer race.
c) Insert outer races of bearings. When the housing
half has reached ambiet temperature, drive outer
races of bearings up to the stop, using a copper
punch.
d) Insert gears again.
e) Fill space between seal and dust lips of shaft seal
rings with a high quality bearing grease (KLUEBER

The necessary time for a complete polymerization is
5 hours: we recommend therefore to clean carefully
the mating surfaces with Loctite 7063 cleaner be-
fore applying the Loctite 518 and wait the requested
time before the spin test.
g) Drive parallel pins into housing to align housing
halves, before tightening.
h) Apply Loctite 243 on to mounting bolts (item 2 and 3,
Fig. 5-7a) and torque them to 40 Nm (30 ft lb).
