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™ dis-
tributors. (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, commuta-
tor set, manifold rotor set, wear plate and housing 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 MAX-
IMUM 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 corrosion resistant
grease recommended in the material section. Press the
new bearing/bushing into the counterbore at the
mounting flange end of the housing, using the appro-
priate sized bearing mandrel, which will control the
bearing/ bushing depth.
Torqlink™ housings require the use of bearing mandrel
to press bearing/ bushing (19) into the housing to a
required depth of 0.151/0.161 in. (3.84/4.09 mm) from
the end of the bearing counterbore.

SECTION 3 - CHASSIS & TURNTABLE
NOTE: Bearing mandrel must be pressed against the lettered end
of bearing shell. Take care that the housing bore is square
with the press base and the bearing/bushing is not cocked
when pressing a bearing/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 ADE-
QUATE BEARING SUPPORT AND CORRECT RELATIONSHIP TO ADJACENT COM-
PONENTS WHEN ASSEMBLED.
BECAUSE THE BEARING/BUSHINGS (13) AND (19) HAVE A PRESS FIT INTO THE
HOUSING THEY MUST BE DISCARDED WHEN REMOVED. THEY MUST NOT BE
REUSED.
