Orbital Dispenser Assembly
Reassemble the orbital dispenser performing the follow-
ing procedure:
1. Assemble upper housing (3) to motor assembly (6)
with four screws (4) and lockwashers (5). Torque
the screws to 16-18 in-lb (1.81-2.03 N•m).
2. If you are not using a coupler repair kit, install o-ring
(12) onto the tube assembly (13).
3. Apply a small amount of removable Loctite
®
641
anaerobic sealant to the inner diameter of the
orbiter coupler assembly bearing (24). Refer to F
6. Loctite sealant is provided in bearing repair tool
kit 241569.
4. Wipe off any excess sealant after tube assembly.
5. Insert tube assembly (13) into upper housing (3)
and through the tube support bearing in motor
assembly (6). Push the tube assembly into the
counterbore at the top of the upper housing.
6. Prior to installation, lubricate o-ring (12) with
PARKER-O-LUBE
™
or an equivalent seal lubricant.
7. If the 3/4-16 swivel fitting (1) on the orbital dispenser
has been separated from the inlet cap (2), apply
Loctite 272 Threadlocker or an equivalent to the
3/4-16 male threads on the fitting and assemble the
fitting to the inlet cap.
8. Install the inlet cap/swivel fitting assembly over the
tube assembly (13). Screw the fitting onto the upper
housing (3) until the tube assembly is firmly
clamped against the upper housing.
9. Assemble lower housing (150) to the motor assem-
bly (6) with four screws (7) and lockwashers (5).
Torque the screws to 16-18 in-lb (1.81-2.03 N•m).
10. Install the bellows seal (140) and nozzle guard (80).
11. Assemble nozzle (15) to the tube assembly (13).
Torque the nozzle to 12-15 in-lb (1.36-1.69 N•m).
12. Install nozzle guard (80).
13. Allow Loctite anaerobic sealant to cure for 24 hours.
14. Reassemble orbital dispenser to dispense valve. Be
sure the 3/4-16 (37° SAE male) fitting on dispense
valve is free of fluid material residue.
15. Connect orbital dispenser cable to motor control
cable.
CAUTION
Apply sealant sparingly. If an excessive amount of
sealant is applied between the tube end and tube sup-
port bearing, the sealant may contaminate the bear-
ing, and result in bearing failure.
