Disassembly/Assembly Instructions - Right Angle Tools

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.

Once the proper rotor/plate clearance is achieved wrench tighten the pinion. (Torque to 17N·m/150 in. lbs.)

Apply the

95842

Dynabrade Air Lube (10W/NR or equivalent) to the

01480

Blades and install them onto the rotor.

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:

Press the

01041

Gear Oil Fitting into the

02041

Gear Oil Plate.

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.)

Press the

02033

Needle Bearing into the housing.

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.

Align the hex shaped I.D. area of the gear with that of the spindle and press the gear into place.

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.

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.

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.)

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:

Install the

30703

Counterweight onto the

30704

Shaft, aligning the screw hole with the pilot hole in the shaft.

Apply a small amount of the Loctite

#567 (or equivalent) to the threads of the

97173

Set Screw.

Use a 2mm hex key to install the

97173

Set Screw into the

30703

Counterweight and secure the counterweight to the

30704

Shaft.

Use the raised outer diameter of the

96216

Bearing Press Tool and the

96232

Arbor Press (#2) to press the

30705

Bearings (2) into the

30702

Balancer Shaft.

Install the

97172

Snap Ring into the

30702

Balancer Shaft.

Install the balancer shaft assembly onto the

30704

Shaft.

Apply a small amount of the Loctite

#567 (or equivalent) onto the threads of the

97174

Screw. Hold the

30703

Counterweight stationary with a 19mm open-end wrench.

Use a Phillips

screwdriver to tighten the

97174

Screw into the

30704

Shaft.

Install the

30700

Boot and the

30701

Plate, aligning the screw holes.

Install the

97175

Screws (4) securely.

10.

Install the

30709

Boot Clamp around the

30700

Boot and use a HEAT GUN to shrink-fit the clamp, securing the boot to the

02052

Housing.

11.

Install the pad.

Orbital Head 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 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.
