8.
Apply a generous amount of clean, corrosion resistant
grease to lower (outer) housing bearing/bushing (19).
Install coupling shaft (12) into housing (18), seating it
against thrust bearing (15).
OUTER BEARING (19) IS NOT LUBRICATED BY SYSTEM HYDRAULIC FLUID. BE
SURE IT IS THOROUGHLY PACKED WITH RECOMMENDED GREASE.
NOTE:
Coupling shaft (12) will be flush or just below housing wear
surface when properly seated with coupling shaft (12).
Coupling shaft must rotate smoothly on thrust bearing
package.
9.
Apply a small amount of clean grease to a new seal ring
(4) and insert it in housing (18) seal ring groove.
NOTE:
One or two alignment studs screwed finger tight into hous-
ing (18) bolt holes, approximately 180 degrees apart, will
facilitate assembly and alignment of components required
in the following procedures. Studs can be made by cutting
off heads of 3/8-24 UNF 2A or 5/16-24 UNF 2A bolts as
required that are over 0.5 inch (12.7 mm) longer than bolts
(1) used in motor.
10.
Install drive link (10), long splined end down, in coupling
shaft (12) and engage drive link splines in mesh with
coupling shaft splines.
NOTE:
Use alignment marks on coupling shaft and drive link
before disassembly to assemble drive link splines in their
original position in mating coupling shaft splines.
