8. Loosen the 8 socket head cap screws on the flange
mounting using a 4mm allan wrench.
9. Withdraw the flange from the shaft while holding the
flange in a special fixture.
10. Turn the motor around again. Attach a mandrel and
press the output shaft with bearing out of the motor
housing with the help of a lever press.
Assembly
1. The output shaft with pressed on and adjusted
tapered roller bearing and cylindrical shaft is to be
centrically positioned onto the housing edge. Press
the complete assembly into the housing to the limit
stop with the help of the press.
NOTE: Do not jam.
2. Before mounting the flange, put a mounting sleeve
onto the shaft.
NOTE: Be sure that the seal is thoroughly oiled.
3. Position the flange with slight pressure into the
housing. Take care to avoid damage to the seals.
4. Screw in the 8 socket head cap screws. Using a
Torque wrench, tighten to 80 in lb (8 Nm).
5. After turning the motor around introduce the control
sleeve. Make sure that the cylindrical roll of the out-
put shaft clicks into the groove of the control sleeve.
6. Insert the O-ring into the housing.
7. Installation of the check valves:
Insert 2 ball valves and carefully drive them in using
a mandrel.
8. Insert the limit stop and put the filler into position for
the lower valve.
9. Put the cardan shaft into position. Note that the
marked tooth must comply with the marking on the
control sleeve.
10. Position the intermediate disk.
11. Insert the O-ring into the recess of the displacer.
12. Place the displacer so that the tooth marking on the
cardan shaft on the displacer side meshes with the
tooth base of the rotor gearwheel that is located
centrally at the lowest point in the outer profile of the
rotor gearwheel. This is only possible at 6 positions.
13. Insert O-ring.
14. Insert spacer.
15. Remount cover, tighten the 7 hexagon bolts using a
torque wrench (torque to 60Nm 43 ft lb). The output
shaft should turn easily.
2.15 DRIVE MOTOR (PARKER)
Disassembly and inspection
1. Place the Torqlink™ in a soft jawed vice, with cou-
pling shaft (12) pointed down and the vise jaws
clamping firmly on the sides of the housing (18)
mounting flange or port bosses. Remove manifold
port O-Rings (18A) if applicable.
IFTHETORQLINK™ IS NOT FIRMLY HELD IN THE VISE, IT COULD
BE DISLODGED DURINGTHE SERVICE PROCEDURES, CAUSING
INJURY.
2. Scribe an alignment mark down and across the
Torqlink™ components from end cover (2) to hous-
ing (18) to facilitate reassembly orientation where
required. Loosen two shuttle or relief valve plugs
(21) for disassembly later if included in end cover. 3/
16 or 3/8 inch Allen wrench or 1 inch hex socket
required.
