To Assemble (Continued):
10. Lubricate the 56073 Vanes with the 95842 Dynabrade Air Lube (10W/NR or equivalent) and install them into the rotor.
11. Install the 69350 Cylinder so that the short line-up pin fits into the front bearing plate.
12. Install the 58368 Bearing into the 57891 Rear Bearing Plate.
13. Use the small end of the 57091 Bearing Press Tool and the arbor press to install the rear bearing/plate onto the shaft balancer as is shown in
Drawing 4. Press the bearing/plate down until it touches the cylinder. Check the fit between the bearing plates and cylinder. Grasp the outer diameter of
the bearing plates, one in each hand. Twist the plates back and forth. It is important to achieve a snug fit between the bearing plates and the cylinder. A
snug fit will trap the cylinder while still allowing it to be twisted back and forth. A loose fit will not achieve proper preload of the motor bearings.
14. Install the 69352 Seal into the cylinder and apply a small amount of the Dynabrade Air Lube onto the o-ring.
15. Slip 59058 Lock Ring over the shaft balancer.
16. Use mark on the edge of the motor opening to identify the location of the line-up notch on the inside of the housing.
17. Install the motor assembly into the housing. Be certain that the line-up pin enters the notch in the housing.
18. Use the 57092 Collar to carefully hold the tool in a vise so that the large end of the shaft balancer is pointing up.
19. Use the 56058 Lock Ring Tool to tighten the 59058 Lock Ring by turning it clockwise. (Torque to 28 N•m/250 in.- lbs.)
Valve and Speed Regulator Assemblies:
1. Secure housing in vice using 57092 Collar or padded jaws.
2. Remove inlet bushing, 01468 Spring, 58365 Tip Valve and 01464 Seal from housing. Remove 94590 Pin from housing, lever and comfort platform.
3. Remove 95697 Retaining Ring. Press the speed regulator and valve stem out of the housing. Remove the 01025 O-Rings (2) and 98459 O-Ring.
4. Place new 01025 O-Rings (2) on the speed regulator and a new 98459 O-Ring on the valve stem. Then place in housing with valve stem. Install new
95967 Retaining Ring. Apply a small amount of pneumatic tool oil to valve o-rings.
5. Place new 01464 Seal in housing. Using tweezers or needle nose pliers, place the tip valve into housing so that the tip valve goes under the valve
stem. Place new 01468 Spring into housing so small end is towards tip valve.
6. After threaded surfaces have been properly cleaned and primed, apply a small amount of #567 Loctite
bushing and tighten into housing to 23 N•m/200 in.- lbs.
7. Install lever and comfort platform on housing with 94590 Pin centered on housing.
Note: Motor should operate at between 4,500 and 5,500 RPM for 5,000 RPM Models and 7,000 and 8,000 RPM for 7,500 RPM Models at 6.2 bar (90 PSIG).
RPM should be checked with a tachometer. Before operating, we recommend that 2-3 drops of Dynabrade Air Lube P/N 95842 (or equivalent) be placed
directly into the air inlet with throttle lever depressed. Operate the machine for approximately 30 seconds before application to workpiece to determine if
machine is working properly and safely and to allow lubricating oils to properly dispense through machine.
