Slide another bearing onto the rotor with the
writing on the outer race facing away from the
rotor and the other bearing.
Slide a washer (3) onto the rotor. Note that
the washer is thinner than the spacer (8) used
on the other end of the rotor.
Securely tighten hex nut (2) on the end of the
rotor (left hand thread).
Repeat the bearing/shim/bearing assembly on
the opposite end. Slide spacer (8) onto the
rotor. Securely tighten driver sleeve (9) on the
end of the rotor (left hand thread).
6) Rotor Square Head Housing Assembly
Install the upper bearing cup (7) over the
bearings on the driver sleeve (9) end of the
rotor assembly.
Clamp the motor housing (13) in a vise with
the motor shaft facing upward. Apply a
liberal amount of grease to both ends of driver
(10) where the driver contacts the driver
sleeve slot and the hydraulic motor drive shaft.
Insert the driver into the driver sleeve. The
grease will hold the driver in place during
assembly. Hold the rotor vertically with the
driver pointing downward. Align the rotor so
the slot in the driver lines up with the flat
surfaces on the shaft of the hydraulic motor.
Also align the upper bearing cup (7) slot to
mate with the motor housing (13).
Engage the driver with the hydraulic motor
shaft.
