Motor Reassembly:

Important: Be certain all parts are cleaned, properly greased and in good repair before reassembly.

2. Place 50435 Key onto rotor shaft.

3. Press bevel pinion into place. Secure 95939 Ring in place.

4. Place the correct number of shims from the 01277 Shim Pack between the front bearing and front bearing plate to achieve a .0015 inch spacing between

the front bearing plate and 07106 Rotor when forward pressure is applied to both the bearing plate and the rotor toward the bevel pinion.

5. Place the blades into rotor slots.

Note: Blades should be lightly lubricated with Dynabrade Air Lube P/N 95842 (or equivalent) before installation in rotor slots.

6. Place cylinder over rotor and blade assembly. The scalloped end goes towards the front plate.

7. Place the 07114 Rear Bearing Plate (with 01007 Bearing pressed into place) over the rotor and line-up short pin on cylinder with the small hole in the

rear plate and press into place.

8. Place the bevel pinion into a soft jaw vise and tighten the governor assembly (07124 Governor Cage) to 9.0 N•m (80 lb. – In.) (left hand thread).

9. Place complete motor assembly into housing.

10. Tighten 02626 Adjustment Bushing into 52090 Adapter to 50 N•m (450 lb. – In.). Add 2 drops of #271 loctite or equivalent to threads of adjustment

bushing before tightening.

11. Tighten 52090 Adapter into housing with 39.5 N•m (350 lb. – In.).

12. Secure inlet bushing into vise. Replace 02631 Nut and 01746 O-Ring. Swivel 07141 Valve Body to desired throttle lever position. Tighten 02631 Nut to 45

N•m (400 lb. – In.).

13. Unroll 07136 Grip back into place.

Spindle Reassembly:

1. Press bevel gear into place on 52117 Spindle.

2. Press 50431 Bearing up against shoulder.

3. Tighten 52118 Spindle Nut to 34 N•m (300 lb. – in.).

4. Place 52088 Spacer up against the bearing.

5. Mount 50412 Felt Ring over spindle nut and down inside 52088 Spacer.

6. Place 52089 Washer with the deeper counter bore toward the felt ring.

7. Slide the spindle assembly down into the housing lining up the small end of the spindle into the 12152 Bearing.

8. Place the correct number of shims from the 52120 Shim Pack checking for backlash (back and forth clearance in the gear teeth while pressing down into

the housing). Note: Minimal backlash of the gear set is recommended.

9. Replace 52091 Retainer. Line up 5 hole pattern and secure with (5) 95897 Screws.

Note: Always check tool RPM before mounting any wheel, disc or accessory, with a tachometer, while maintaining 90 PSIG at the tool inlet under a no load

condition. If tool is operating at a higher speed than the RPM marked on the tool, the tool should be serviced to correct the cause before use.

Tool assembly is complete.

Important:

The regular maintenance of any air tool will contribute to greater efficiency of tool and will prolong tool life. The failure of quality pneumatic air motors can most

often be traced to an unclean air supply or the lack of lubrication. Air pressure easily forces dirt or water contained in the air supply into motor bearings

causing early failure. It often scores the cylinder walls and the rotor blades resulting in limited efficiency and power. Frequent drainage of water traps in air

lines is recommended. Each tool on each drop should also be equipped with a secondary air processing unit. This consists of an in-line Filter-Regulator-

Lubricator. All Dynabrade air tools must be used with a Filter-Regulator-Lubricator to maintain all warranties. Our warranty obligation is contingent upon proper

use of our tools and cannot apply to equipment which has been subject to misuse such as unclean air, wet air or a lack of lubrication during the use of the tool.
