Disassembly/Assembly Instructions - Right Angle Tools
6.
Check the clearance between the rotor and the bearing plate with a .001 thick feeler gauge. Clearance should be .001” to .0015” (0.03-0.04mm). If it’s necessary, readjust
clearance by repeating steps 3-5 with different thickness shims.
7.
Once the proper rotor/plate clearance is achieved wrench tighten the pinion. (Torque to 17N·m/150 in. lbs.)
8.
Apply the
95842
Dynabrade Air Lube (10W/NR or equivalent) to the
01480
Blades and install them onto the rotor.
9.
Use the
96216
Bearing Press Tool so that it pushes against the outer race of the
02696
Bearing and install it into the
02676
Rear Bearing Plate with the arbor press.
10.
Place the pinion on the tool plate of the arbor press so that the rear portion of the rotor is pointing up.
11.
Install the
01476
Cylinder so that it rests against the
01478
Bearing Plate.
Note:
Make sure that the air inlet passage of the cylinder will properly aligned with the air inlet
passage in the
02676
Bearing Plate.
12.
Use the
96216
Bearing Press Tool so that it pushes against the inner race of the
02696
Bearing and install the rear bearing/plate assembly onto the rotor with the
arbor press.
Important:
Carefully press the rear bearing/plate assembly onto the rotor until it touches the
01476
Cylinder. A “snug” fit should exist between the bearing
plates and cylinder. If it is too tight the rotor will not turn freely and will cause damage to the bearings. If it is too loose the proper bearing preload will not be achieved.
13.
Apply a small amount of grease to the seal of the
02696
Rear Bearing and place the
02679
Shield against the seal of the bearing.
14.
Install the motor assembly into the housing so that the air passage node of the rear bearing plate aligns with the air passage notch inside the housing.
15.
Apply a small amount of Loctite
®
#567 (or equivalent) to the threads of the motor housing and use a 34mm (or an adjustable wrench) to connect the angle head assembly
to the motor housing. (Torque to 34 N-m/300 in. lbs.)
Motor Assembly Complete.
Right Angle Housing Assembly:
1.
Press the
01041
Gear Oil Fitting into the
02041
Gear Oil Plate.
2.
Carefully apply two drops of Loctite
®
#680 (or equivalent) to the recessed area of the
02052
Housing and press the gear oil plate along with gear oil fitting into the housing.
(Allow 30 minutes for the adhesive to cure.)
3.
Press the
02033
Needle Bearing into the housing.
4.
Position the
96239
Bearing Press Tool so that it rests against the inner race of the
54520
Bearing and press the bearing onto the spindle.
5.
Align the hex shaped I.D. area of the gear with that of the spindle and press the gear into place.
6.
Apply a small amount of Loctite
®
#567 (or equivalent) to the mating threads of the
02052
Housing. Connect these parts while being aware of the right and left hand threads.
7.
Place the
52296
Repair Collar around the motor housing and position the tool in a vise so
that the angle housing end of the tool is pointing up.
8.
Use a 34mm or adjustable wrench on the
01461
Lock Nut while holding the angle housing
stationary with one hand.
Note:
The throttle lever can be positioned in 360˚ to the desired location.
Allow for additional rotation when tightening the lock nut. (Torque to 34 N-m/300 in. lbs.)
9.
Reposition the tool assembly in the vise so that the opening in the angle housing, for the
02035
Lock Ring is facing up.
10.
Soak the wicks in the
95848
Gear Oil before installing them into the
02052
Housing. Install the top wick first followed by the bottom wick. Position truncated side of each
wick toward the end of the pinion gear.
11.
Install the
30704
Shaft into the angle housing. Apply a slight amount of pressure down on the spindle while rotating it back and forth checking for the proper backlash or fit
between the gears. A slight amount of backlash or clearance should exist between the bevel and pinion gears. When a tight fit exist, then add shims as needed placing the
required thickness of shims between the outer race of the
54520
Bearing and the bearing seat in the housing.
12.
Place (1)
01486
Felt Silencer into the
02035
Lock Ring, and apply a small amount of Loctite
®
#567 (or equivalent) to the threads of the
02035
Lock Ring. Use the
50971
Lock Ring Wrench to install the lock ring onto the
02052
Housing. (Torque to 23 N-m/200 in. lbs.)
Right Angle Housing Assembly Complete.
Orbital Head Assembly:

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 air inlet with throttle lever depressed. Operate tool for 30 seconds to determine if tool
is operating properly and to allow lubricating oils to properly penetrate motor. Motor should now be tested for proper operation at 90 PSIG. If motor does not operate properly or
operates at a higher RPM than marked on the tool, the tool should be serviced to correct the cause before use.
