®
Tools (Cont.)
6. Use a .001"(0.3mm) thick feeler gauge to check the clearance between the front bearing plate and the face of the rotor.
7. The clearance should be .001"-.0015" (0.3-0.4mm).
Note: If the clearance needs adjustment, repeat steps 2-5 adding or removing shims as required.
8. Lubricate the 01480 Vanes with the 95842 Dynabrade
®
Air Lube 10W/NR (or equivalent) and install these into the rotor.
9. Install the 01476 Cylinder over the rotor so that the air inlet opening of the cylinder will line up with the air inlet opening in the
02673 Rear Bearing Plate.
10. Use the raised outer diameter of the 96216 Bearing Press Tool and the arbor press to install the 02696 Bearing into the 02673 Rear Bearing Plate.
11. Use the raised inner diameter of the 96216 Bearing Press Tool and the arbor press to install the bearing/plate onto the rotor
.
Note: Carefully press the bearing/plate down until it just touches the cylinder
. This will establish a snug fit between the bearing plates and the cylinder.
12. Apply a small amount of light grease to the seal of the 02696 Bearing and adhere the 02679
Shield against the bearing.
13. Carefully slide the motor assembly into the 01546/57779 Housing.
14. Apply a small amount of the Loctite
®
#567 (or equivalent) to the threads of the 01546/57779 Housing.
15. Use a 3mm adjustable pin spanner wrench or the 50971 Lock Ring Tool to tighten the exhaust cover onto the 01546/57779 Housing.
(Torque to 28N•m/250 in. lbs.)
16. Install the 57975 Clamp onto the boot assembly.
17. Install the boot assembly with the clamp, aligning them on the 57962 Exhaust Cover. Tighten the clamp. (Torque to 7N•m/6 in. lbs.)
18. Use the 95266 Hex Key (3 mm) to install the sanding attachment.
Motor Assembly Complete.
Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.
Important: Before operating , place 2-3 drops of Dynabrade Air Lube (P/N 95842) directly into inlet with throttle lever depressed. Operate tool for 30
seconds to allow air lube to properly lubricate internal motor components. Motor should now be tested for proper operation at 90 PSIG (6.2 Bar, g) max.
If tool operates at a higher RPM than marked on the tool or if vibration and sound levels seem abnormal, the tool should be serviced to correct
the cause before use.
Throttle Positioning Procedure:
Important: Carefully perform this procedure so as not to entirely separate the 01546 Housing from the valve housing. Loosen the 01461 Lock Nut
only enough to make the desired throttle lever adjustment.
1. Place the 52296 Repair Collar around the valve housing and hold it in a vise so that the 01546/57779 Housing is pointing up.
2. Slip the 01558 Collar down onto the valve housing to expose the 01461 Lock Nut.
3. With a firm hold on the 01546/57779 Housing use a 34 mm or an adjustable wrench to turn the lock nut clockwise to loosen the 01546/57779 Housing
from the valve housing.
4. Orient the throttle lever to the operators desired grip and positioning. Note: Allow for additional rotation of the 01546/57779 Housing as the 01461
Lock Nut is tightened.
5. Grasp the 01546/57779 Housing firmly to reduce its rotation. Use a 34 mm or an adjustable wrench to tighten the 01461 Lock Nut.
Torque to 45 N•m/400 lbs. in.
6. Slip the 01558 Collar back over the 01461 Lock Nut.
Throttle Positioning Procedure Complete.
