HY13-1512-006-M1/USA
Torqmotor™ Service Procedure
TC, TS, TB, TE, TJ, TF, TG, TH and TL Series
Parker Hannifi n Corporation
Hydraulic Pump/Motor Division
Greeneville, TN 37745 US
34
NOTE NOTE: Series TG or TH may have a rotor
set with two stator halves (8B & 8D) with
a seal ring (4) between them and two sets
of seven vanes (8C & 8E). Discard seal
ring only if stator halves become disas-
sembled during the service procedures.
NOTE NOTE: A polished pattern on the wear
plate from rotor rotation is normal.
Check rotor,
vane clearance
11. Place rotor set (8) and wear plate (9) on a
fl at 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 ro-
tor lobe to roller vane clearance with a feeler
gage at this common centerline. If there is
more than .005 inches (0.13 mm) of clear-
ance, replace rotor set. SEE FIGURE 16.
NOTE 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 clear-
ance at both ends of rotor.
Remove & in-
spect
drive link
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. SEE FIGURE 17. Remove and
discard seal ring (4) from housing (18).
Remove thrust
bearing
13. Remove thrust bearing (11) from top of
coupling shaft (12) if Torqmotor is a Series
TF, TG, TH or TL. Inspect for wear, brinel-
ling, corrosion and a full complement of
retained rollers. SEE FIGURE 18.
