Spindle Lock Assembly:
1. Install a new 97156 O-ring onto the plunger and apply a small amount of Dynabrade Gear Oil (P/N 95848 or equivalent) to O-ring.
2. Install 98285 Spring onto the housing bushing and insert the 25273 Plunger Assembly through the spring.
3. Install the plunger assembly into the spindle lock bushing. Note: Rotating the plunger while inserting prevents damage to the o-ring.
Spindle Lock Assembly Complete.
Motor Assembly:
1. Install 01010 Spacer onto the rotor front mandrel.
2. Select .003" (.08mm) thickness shims from the 01121 Shim Pack and install these into the 25236 Front Bearing Plate.
3. Install 98242 O-Ring into front bearing plate groove and install 01007 Bearing, into the front bearing plate.
4. Position the rotor in a vise with aluminum or bronze jaws so that the rotor spindle is pointing up. Install the front bearing/plate onto the rotor.
5. Apply a small amount of the Loctite
Using a hook/pin spanner wrench. Remove the assembly from the vise.
6. Use a .001" (0.3mm) thick feeler gauge to check the clearance between the front bearing plate and the face of the rotor. The clearance should be .001"-.0015" (0.3-0.4mm).
Note: If the clearance needs adjustment repeat steps 2-6 adding or removing shims as required.
7. Lubricate 25234 Vanes (4) with the 95842 Dynabrade Air Lube 10W/NR (or equivalent) and install these into the rotor.
8. Install 25235 Cylinder over the rotor so that the air inlet opening of the cylinder will line up with the air inlet opening on the 25237 Rear Bearing Plate.
9. Install 01206 Bearing into 25237 Rear Bearing Plate.
10. Use the raised inner diameter of 96244 Bearing Press Tool and the arbor press to install the rear 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.
11. Fasten the pinion gear in a vise with aluminum or bronze jaws so that the rear bearing/plate pointing up.
12. Apply a small amount of the Loctite
turn counterclockwise. Insure 25295 Pin stays engaged in slot on 25290 Governor Base during assembly. Use a 19 mm crowfoot, tighten Governor base to Rotor
(Torque to 9N•m/80 lbs. in.)
13. Carefully slide the motor assembly into the housing.
14. Place padding around the housing and carefully hold the housing stationary in a vise. Apply a small amount of the Loctite
Use an adjustable wrench tighten 25257 Cup Nut onto housing. Turn clockwise. (Torque to 30N·m/265 lbs. in.)
Important: Allow 30 minutes for the adhesives to cure before operating the tool.
Run the tool to make sure that the air motor is functioning properly before installing the right angle gears. Motor Assembly Complete.
Spindle/Gear Assembly:
1. Position the spindle in the arbor press so that the threaded end is pointing down.
2. Use a 19/32" deep well socket as a press tool, install the 01036 Bearing onto the spindle and against the step.
3. Use a 19/32" deep well socket as a press tool and install the 25241 Bevel Pinion onto the spindle.
4. Prepare the 25264 Wick by soaking in 95848 Gear Oil and then install the wick onto the spindle.
5. Press 02057 Bearing using 96243 Press Tool ( sold separately ) onto spindle until the spindle is flush with the bearing top.
6. Place padding around the housing and carefully hold the housing stationary in a vise with the right angle spindle opening facing up.
Important: Follow these steps to adjust the fit or "backlash" of the spiral bevel gear/pinion gear.
7. Install the spindle assembly into the housing align wick shape to housing contour. Mesh bevel and pinion gears together.
8. Apply a small amount of downward force on the spindle and rotate the spindle 360˚. The rotation should be smooth without any tight feel or binding of the gear teeth. Next,
rotate the spindle forward and backward to check the amount of backlash (free movement between the gear teeth). The correct fit should be minimal backlash without any
binding of the gear teeth. Add or remove shims to adjust the gear "backlash".
9. Place the 53609 Felt Seal into the 25265 Retainer recess bore.
10. Apply a small amount of the Loctite
LEFT HAND THREAD Turn counterclockwise. (Torque to 23N•m/203 lbs. in.)
11. Re-check the fit of the gears by hand before connecting the tool to the air supply. The correct fit should be minimal backlash without any binding of the gear teeth. Add or
remove shims to adjust the gear fit if necessary.
12. Use the 95541 Lubricant Gun to apply the 95848 Gear Oil Lubricant required for the lubricating wick prime the plunger before adding gear oil to housing. Inject three full
plunges of the gear oil into the 01041 Gear Oil Fitting on the front of housing.
Note: Inject three full plunges of gear oil into the lubricant fitting after operating the tool every 24-hour interval of use.
Right Angle Assembly Complete:
Muffler Assembly:
1. Install 25282 Silencer (Cross section size: 7.5 mm) up and inside recess diameter of 25278 Muffler Cover.
2. Install the 98281 O-Ring (Cross section size: 2.4 mm) into the inside groove of the muffler cover.
3. Install the 98282 O-Ring (Cross section size: 2.0 mm) into the outside groove of the muffler cover.
4. Install 25278 Muffler Cover (the side with the smaller hole) onto 25281 Muffler Stem Assembly.
5. Install 25283 Silencer (Cross section size: 13 mm) into housing cavity.
6. Apply a small amount of the Loctite
onto the housing. Rotate 25281 Muffler Stem Assembly until slot aligns with housing raised boss. Thread socket head cap screw into housing using a 5/32" hex key
(Torque to 7N•m/60 lbs. in.).
Muffler Assembly Complete.
Final Assembly:
Important: Allow 30 minutes for the adhesives to cure before operating the tool. Install and properly position all guarding and auxiliary side handle. Before installing
mounting flanges or any abrasive product, the air tool must be tested for proper operation. Follow these steps to verify the correct rated operating speed of the tool.
1. Supply 3 drops of 95482 Dynabrade Air Lube 10W/NR (or equivalent) into the air inlet bushing of the tool while the throttle lever is depressed. Allowing the oil to flow into
the air motor.
2. Release the throttle lever.
3. With the air supply valve in the OFF position, carefully connect the tool to the air supply hose. Note: Use a wrench to hold the air inlet bushing on the tool stationary when
installing the air supply connection.
4. Once the tool is connected to the air supply, turn the supply valve to the ON position. Run the tool and use a tachometer to verify the rated operating speed (RPM) of the tool.
The tool should operate within 5% of the maximum rated RPM. The tool RPM must never exceed the maximum rated RPM with the operating air supply pressure reading 90
PSIG (6.2 bar g) at the air inlet of the tool. To adjust free speed add or remove shims. Adding shims will increase the speed, removing shims will reduce the tool free speed.
Once the correct rated operating speed for the tool is verified, disconnect the tool from the air supply and install the proper flanging and abrasive product.
Final Assembly Complete. Tool Assembly Complete.
