20. Inspect housing (18) assembly for cracks, the machined
surfaces for nicks, burrs, brinelling or corrosion. Remove
burrs that can be removed without changing dimen-
sional characteristics. Inspect tapped holes for thread
damage. If the housing is defective in these areas, dis-
card the housing assembly.
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 inch (0.025 mm). A
bearing, bushing, or thrust washer that does not pass
inspection must be replaced. If the housing has passed
this inspection the disassembly of the Torqlink™ is com-
pleted.
