NOTE: The manifold is constructed of plates bonded together to
form an integral component not subject to further disas-
sembly for service. Compare configuration of both sides oft
hem an if old to ensure that same surface is reassembled
against the rotor set.
10. Remove rotor set (8) and warplane (9), together to retain
the rotor set in its assembled form, maintaining the
same rotor vane (8C) to stator (8B) contact surfaces. The
drive link (10) may come away from the coupling shaft
(12) with the rotor set, and wearplate.You may have to
shift the rotor set on the warplane to work the drive link
out of the rotor (8A) and warplane. Inspect the rotor set
in its assembled form for nicks, scoring, or spalling on
any surface and for broken or worn splines. If the rotor
set component requires replacement, the complete
rotor set must be replaced as it is a matched set. Inspect
the warplane for cracks, brinelling, or scoring. Discard
seal ring (4) that is between the rotor set and wearplate.
NOTE: The rotor set (8) components may become disassembled
during service procedures. Marking the surface of the rotor
and stator that is facing UP, with etching ink or grease pen-
cil before removal from Torqlink™ will ensure correct reas-
sembly of rotor into stator and rotor set
intoTorqlink™.Marking all rotor components and mating
spline components for exact repositioning at assembly will
ensure maximum wear life and performance of rotor set
andTorqlink™.
NOTE: Series TG Torqlinks™ may have a rotor set with two stator
halves (8B) with a seal ring (4) between them and two sets
of seven vanes (8C). Discard seal ring only if stator halves
become disassembled during the service procedures.
NOTE: A polished pattern on the wear plate from rotor rotation is
normal.
11. Place rotor set (8) and wear plate (9) on a flat
surface
and center rotor (8A) in stator (8B) such that two
rotor lobes (180 degrees apart) and a roller vane
(8C) centerline are on the same stator centerline.
Check the rotor lobe to roller vane clearance with a
feeler gage at this common centerline. If there is
more than 0.005 inches (0.13 mm) of clearance,
replace rotor set.
NOTE: If rotor set (8) has two stator halves (8B & 8D) and two sets
of seven vanes (8C & 8E) as shown in the alternate con-
struction TG rotor set assembly view, check the rotor lobe
to roller vane clearance at both ends of rotor.
