8. (C2) Bearings Installation - Gear End
NOTICE
The maximum load applied to this all thread rod must never exceed 5 tons.
33. Locate the 2 spherical roller bearings (11) that are to
be installed on the gear end of both rotors. The
gear end bearings and the drive end bearings are
the same physical size and appear to be the same
part. It is important that the correct bearings are
installed on the gear end as they have tighter
internal clearances that the drive end bearings. The
part number and C2 should also be marked on
these bearings.
34. Apply oil to the drive and idler rotor bearing bores
in the gear end bearing housing. Lubricate
internal surfaces and rollers of bearings with oil.
Drain excess oil from bearing before installation .
Oil should not be dripping from bearing in
mounted position.
35. Place a bearing over the idler rotor shaft with the
numbers on the bearing facing up. Screw (T8) and
(T3) into the end of the idler rotor shaft. Place (T15)
and (T22) over the all thread rod (T3). Place a portable
hydraulic cylinder with a hollow center (T28) over the
all thread rod and onto the driver tool. Put (T7), (T2)
and (T1) over the all thread rod and tighten it up
against the hydraulic cylinder. Press the bearing onto
the rotor shaft using the hydraulic cylinder.
36. Repeat step 34 for the drive rotor on the gear end.
