Be sure that a generous amount of clean wheel bearing grease is applied to housing bearing (29) then install
coupling shaft (25) into housing (28) seating it against thrust washer (32). The coupling shaft must rotate
smoothly on the thrust bearing.
Insert new drive pin (26) if it was removed, into the commutator (24) drive pin hole until it bottoms out.
Do not force commutator into bore. It is a close slip fit and must rotate.
Install commutator (24) assembly into housing (28) commutator bore. The commutator must not be cocked as it
enters the bore and the drive pin (26) must be in line with the coupling shaft (25) commutator drive pin slot
indicated by the timing mark. Engage the drive pin (26) protruding from the commutator into the coupling shaft
drive pin slot, rotating the coupling shaft if necessary. The commutator must be below the housing wearplate
surface when correctly seated.
The commutator drive pin (26) and coupling shaft (25) drive pin slot, at this point in the
assembly, are visible through the commutator center cavity for coupling pin engagement
purposes in addition to the timing mark.
Install either end of the drive link (23) through the commutator (24) cavity and engage the lower drive link splines
into mesh with the internal splines in the coupling shaft (25). A spline valley on both ends of the drive link will
now be in line with the commutator drive pin (26) and coupling shaft timing mark.
Apply a small amount of clean grease to a new seal ring (21) and insert the seal ring into housing (28) seal ring
Place assembled rotor set (16) on a clean work surface. Apply a small amount of clean grease to a new seal ring
(21) and insert the seal ring into the stator (19) seal ring groove.
Place wearplate (20) either side up, onto the rotor set (16) and align wearplate bolt holes with the stator (19) bolt
