Assembly
Replace all seals and seal rings with new ones each time
you reassemble the Torqlink™ unit. Lubricate all seals and
seal rings with SAE 10W40 oil or clean grease before
assembly.
NOTE: Individual seals and seal rings as well as a complete
seal kit are available. The parts should be available
through most OEM parts distributors or Parker
approved Torqlink™ distributors. (Contact your local
dealer for availability).
NOTE: Unless otherwise indicated, do not oil or grease
parts before assembly.
Wash all parts in clean petroleum-based solvents before
assembly. Blow them dry with compressed air. Remove
any paint chips from mating surfaces of the end cover,
commutator set, manifold rotor set, wear plate and hous-
ing and from port and sealing areas.
SINCE THEY ARE FLAMMABLE, BE EXTREMELY CAREFUL WHEN
USING ANY SOLVENT. EVEN A SMALL EXPLOSION OR FIRE
COULD CAUSE INJURY OR DEATH.
WEAR EYE PROTECTION AND BE SURE TO COMPLY WITH OSHA
OR OTHER MAXIMUM AIR PRESSURE REQUIREMENTS.
1. If the housing (18) bearing components were
removed for replacement, thoroughly coat and pack
a new outer bearing/bushing (19) with clean corro-
sion resistant grease recommended in the material
section. Press the new bearing/bushing into the
counterbore at the mounting flange end of the hous-
ing, using the appropriate sized bearing mandrel,
which will control the bearing/ bushing depth.
Torqlink™ housings require the use of bearing man-
drel to press bearing/ bushing (19) into the housing
to a required depth of 0.151/0.161 inches (3.84/4.09
mm) from the end of the bearing counterbore.
NOTE: Bearing mandrel must be pressed against the let-
tered end of bearing shell. Take care that the hous-
ing bore is square with the press base and the
bearing/bushing is not cocked when pressing a bear-
ing/bushing into the housing.
IF THE BEARING MANDREL SPECIFIED IN THE “TOOLS AND
MATERIALS REQUIRED FOR SERVICING” SECTION IS NOT
AVAILABLE AND ALTERNATE METHODS ARE USED TO PRESS IN
BEARING/BUSHING (13) AND (19) THE BEARING/BUSHING
DEPTHS SPECIFIED MUST BE ACHIEVED TO INSURE ADEQUATE
BEARING SUPPORT AND CORRECT RELATIONSHIP TO ADJACENT
COMPONENTS WHEN ASSEMBLED.
