QS-5003 Installation onto Drum Mounted Agitator (Refer to Figure 2) 1. Adapter (47) has two thread sizes: 1-1/2" NPS (M) on one end and 2" NPS (M) on the other end. Choose the proper thread size and place adapter over agitator shaft of drum and screw down securely. 2. Select proper driver shaft (46) and attach it to drive coupling assembly (48) with driver pin (45) and cotter pins (44). Place this assembly on shaft of drum agitator. 3. Slip air motor support (39) down over drive coupling assembly (48) and adapter (47). 4. Tighten air motor support (39) se- curely with screw assembly (43). 5. Install gear box (38) on air motor sup- port (39), being sure to engage shaft of drive coupling assembly (48). 6. Tighten cap screw and hex nut (40 and 42). 7. Connect air supply line to air adjusting valve (52). OPERATION Before operating air motor, lubricate as covered in next section. Open valve to main air line; then slowly open air adjust- ing valve until agitator turns. To extend air motor life, adjust air pressure setting to run motor at about one revolution per second. The agitator should be run continuously while using the tank. PREVENTIVE MAINTENANCE Air Motor Lubrication Failure to properly lubricate the air motor will result in premature mo- tor failure and will void warranty. Lubricate air motor daily by adding 4 or 5 drops of SAE 10 weight oil into air inlet fitting. For convenience, an automatic oiler may be connected to the air inlet. Periodically - Remove air adjusting valve and air strainer and flush motor with a clean suitable solvent. Remove trapped particles from screen in air inlet and clean air strainer felt. Air Motor Gear Box Lubrication Every 2 Days - Remove oil fill plug and check oil level. Proper oil level is indicated on outside of gear box housing. If oil level is low, add 140-weight SAE Gear Oil or a high quality worm gear lubricant. Replace pipe plug and tighten to 20 foot-pounds (27 N-m) of torque. Note Gear box oil is most easily drained just after motor operation, while oil is still warm. Note Do not overfill. Overfilling may cause oil to leak out of vent cap on top of gear box. After first 250 hours of operation, remove gear box and drain gear oil. Refill gear box with 140-Weight SAE Gear Oil or a high quality worm gear lubricant. Replace pipe plug and tighten to 20 foot-pounds (27 N-m) of torque. 6 Months or 2500 Operating Hours - Re- place gear oil according to instructions above. Replace gear oil more often if environment causes oil to become con- taminated during use. REPLACEMENT OF PARTS Removal of Air Motor and Gear Box (Refer to Figure 3 - typical assembly.) 1. Follow pressure relief procedure (Ref. Pg. 1) before removing or loosening any components. 2. Turn off valve to main air supply and disconnect air adjusting valve (65) at nipple (64). 3. Loosen upper cap screw (61) and remove air motor and gear box as- sembly from support (60). Air Motor (Refer to Figure 4) Holes must be drilled for new dowel pins (72) after assembling front plate (77) on new body (76) for alignment of parts. Do not pry front plate (77) or end plate (71) from air motor body (76) with a screw driver; this will dent the surface of the body and plates causing leaks. A puller tool should be used to remove the plate from the motor body while maintaining the position of the shaft. Always install new gaskets (73) when reassembling air motor. Assemble the end plates to the body using an arbor press with a pusher acting on both races of the bearing while rigidly support- ing the opposite (drive) end of the shaft. Gear Box (Refer fo Figure 5) 1. Remove oil fill plug (88) or cover plate (84) and drain gear box lubricant. 2. Remove setscrews (91) and remove gear box from air motor. 3. Disassembly gear box per exploded view, Figure 5. Discard gaskets (87 and 92). Do not remove oil seal (90) unless leakage or seal damage is indicated. 4. If oil seal (90) was removed, inspect seal seating bore in housing (89). Remove any burrs or contaminants from seal seating bore. Burrs or contaminants could distort new oil seal during installation. 5. Inspect gear and shaft assembly (86) for wear grooves, burrs, or con- tamination of seal seating area. If seal seating area is damaged, shaft must be repaired or replaced. 6. Inspect all other parts for wear spots, chipping, or other damage. Replace damaged or worn parts. 7. If oil seal (90) is being replaced, inspect new seal for damage before installing. Use arbor press to install seal. Press fixture diameter must be close fit with gear box bore diameter to avoid damage to seal. Install with inner casing and sealing lip toward bottom of bore. Drive seal squarely into bore to avoid warping. Check that seal is fully seated all around at bottom of bore. 8. Reassemble gear box per exploded view. Install new gaskets (87 and 92). Just prior to assembling gear box with air motor, apply a small dab of thread locking compound (81) to threads of setscrews (91). Connect motor and gear box and torque setscrews (91) to 60 inch-pounds (6.8 N-m), minimum. Refill gear box per gear box lubrica- tion instructions. Approx. 1/8" Gap (top of oil level to bottom of fill line)
