10. Remove rotor set (8) and warplane (9), together to
retain the rotor set in its assembled form, maintain-
ing 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 wear-
plate.You may have to shift the rotor set on the war-
plane 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 war-
plane 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 disas-
sembled during service procedures. Marking the sur-
face of the rotor and stator that is facing UP, with
etching ink or grease pencil before removal from
Torqlink™ will ensure correct reassembly of rotor
into stator and rotor set intoTorqlink™.Marking all
rotor components and mating spline components for
exact repositioning at assembly will ensure maxi-
mum wear life and performance of rotor set and-
Torqlink™.
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 rota-
tion is normal.
11. Place rotor set (8) and wear plate (9) on a flat sur-
face 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 sta-
tor centerline. Check the rotor lobe to roller
vane clearance with a feeler gage at this com-
mon 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 construction TG rotor set assembly view,
check the rotor lobe to roller vane clearance at both
ends of rotor.
12. Remove drive link (10) from coupling shaft (12) if it
was not removed with rotor set and wear plate.
Inspect drive link for cracks and worn or damaged
splines. No perceptible lash (play) should be noted
between mating spline parts. Remove and discard
seal ring (4) from housing (18).
