Motor Assembly Continued:
B.
Slip the
55026
Front Bearing Plate along with the
01007
Bearing onto the
55025
Rotor.
4.
Use a .001" feeler gage to check clearance between the front of the rotor body and the face of the front bearing plate. That clearance
must be .001"-.0015". If it is necessary to adjust the clearance, do this by adding or removing the appropriate thickness in shims.
5.
Apply Dynabrade Air Lube
95842
to the
01185
Blades and install these into the rotor slot.
6.
Install the
01028
Cylinder so that the air inlet area lines up with the air inlet holes in the rear bearing plate.
7.
Use the
96240
Bearing Press Tool and arbor press to install the
02649
Bearing into the
55027
Rear Bearing Plate (press tool against the
outer race of the bearing).
8.
Use the
96240
Bearing Press Tool and arbor press to install the rear bearing/plate onto the rotor (press tool against the inner race of the bearing).
Important:
The fit must be snug between the bearing plates and the cylinder. However, if its' too tight the rotor will turn freely. In that
case the fit must be loosened so that the rotor will turn freely while still maintaining a snug fit.
Planetary Gear Assembly:
1.
Press the front
02552
Bearing onto the front of the planetary carrier.
2.
Install the
04114
Spindle Nut onto the planetary carrier. (Torque to 17 N•m/150 in.-lbs.)
3.
Lubricate the planetary gears, needle bearings, and shafts with P/N
95542
Grease, and install these into the planetary carrier.
4.
Install the
53191
Ring Gear over the planetary carrier so that the set screw and grease fitting notches will orient correctly once placed
into the cover.
5.
Press the rear
02552
Bearing onto the rear of the planetary carrier until it touches the ring gear.
Important:
The fit must be snug between
the bearings and the ring gear. However, if its' too tight the planetary carrier will not turn freely. In that case the fit must be loosened so that
the planetary carrier will turn freely while still maintaining a snug fit.
6.
Install the
55031
Felt Seal into the cover.
7.
Install the planetary carrier assembly(ies) into the cover so that the notches in the ring gear(s) align with the set screw and grease fitting
openings in the cover.
8.
Apply a small amount of Loctite #567 (or equivalent) to the threads of the
04114
Set Screw(s) and install into the cover.
9.
Lubricate the planetary gears through the grease fitting(s) applying 1 plunge at intervals of every 50 hours of use. Order and use the
recommended Dynabrade
95542
Grease Gun to insure the maximum gear life.
Tool Assembly:
1.
Carefully secure the housing in a vise so that the motor opening is facing up. To avoid damaging the housing do not over tighten the vise.
2.
Install the air motor assembly into the housing.
3.
Carefully align the cover and the planetary gear assembly(ies) to the housing and the air motor assembly. (
Left Hand Thread
),
(Torque to 28 N•m/250 in.-lbs.).
4.
Use the
96034
12mm Hex Key to install the
57066
Muffler Body into the housing. Place the
56027
Muffler Insert into the
56028
Muffler
Cap and install these onto the muffler body.
5.
Install the drill chuck and the
53153
Side handle.
Shroud Assembly:
1.
Slide
31900
Hose Cuff onto port extending from
52753
Shroud.
2.
Slide
97029
Hose Clamp onto base of Shroud; ensure that hose clamp is loose. Install Shroud onto
02276
Shroud base.
4.
Install Shroud sub-assembly onto tool, ensuring that
02276
engages
02272
Sleeve and Attach
31926
Vacuum hose to Hose Cuff.
6.
Tighten
53219
Locking Knob and tighten
97029
Hose Clamp.
Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.
Important:
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. Before operating, place 2-3 drops of Dynabrade Air Lube
(P/N
95842
) directly into air inlet with throttle depressed. Operate tool for 30 seconds to determine if tool is operating properly and to allow
lubricating oils to properly permeate motor.

Notice
All Dynabrade motors use the highest quality parts and materials available and are machined to exacting tolerances. The failure of quality pneu-
matic 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.
Our warranty obligation is contingent upon proper use of our tools and cannot apply to equipment which has been subjected to misuse such as
unclean air, wet air or a lack of lubrication during the use of this tool.
