21. If the housing (18) assembly has passed inspection to
this point, inspect the housing bearings/bushings (19)
and (13) and if they are captured in the housing cavity
the two thrust washers (14) and thrust bearing (15). The
bearing rollers must be firmly retained in the bearing
cages, but must rotate and orbit freely. All rollers and
thrust washers must be free of brinelling and corrosion.
The bushing (19) or (13) to coupling shaft diameter
clearance must not exceed 0.010 in. (0.025 mm). A bear-
ing, bushing, or thrust washer that does not pass inspec-
tion must be replaced. If the housing has passed this
inspection the disassembly of the Torqlink™ is com-
pleted.
NOTE: The depth or location of bearing/bushing (13) in relation to
the housing wear plate surface and the depth or location
of bearing/bushing (19) in relation to the beginning of
bearing/bushing counter bore should be measured and
noted before removing the bearings/bushings. This will
facilitate the correct reassembly of new bearings/bushings.
22. If the bearings, bushing or thrust washers must be
replaced use a suitable size bearing puller to remove
bearing/bushings (19) and (13) from housing (18) with-
out damaging the housing. Remove thrust washers (14)
and thrust bearing (15) if they were previously retained
in the housing by bearing (13).
