3. Install .003" (0.08 mm) thick shim into the 55203 Front Bearing Plate.
4. Install the 01825 Bearing into plate and install these onto the rotor.
5. Apply a small amount of Loctite #271 (or equivalent) to the spindle nut threads and install the 55224
Nut and secure it onto the rotor. (Torque to 28 N•m/250 in. lbs.)
6. Use a .001" (0.03 mm) feeler gauge to check clearance between rotor and bearing plate. Clearance
should be .001" to .0015" (0.03 - 0.04 mm). If necessary, adjust clearance by repeating steps 3-5.
Add or remove shims as required.
7. Once the proper clearance is achieved, apply Dynabrade Air Lube P/N 95842 (or equivalent) to the
55204 Vanes (4) and install them.
8. Install the 55201 Cylinder.
9. Use a press tool with a 1.3385" (34 mm) outside diameter and the 96232 Arbor Press (#2) to install
the 02552 Bearing into 55202 Rear Bearing Plate. Use a press tool with an outside diameter of .8070"
(20.50 mm) to install the bearing/plate onto the rotor. Make sure that the 01673 Pin and air inlet
opening line-up with the hole in the rear bearing plate and air inlet opening in the plate and cylinder.
IMPORTANT: Press the bearing/plate onto the rotor until the plate just touches the cylinder. When
this is done correctly, a snug fit is created between the bearing plates and the cylinder.
10. Secure the 55224 Nut in a vise with aluminum or bronze Jaws. Carefully install the governor
assembly. LEFT HAND THREAD (Torque to 25 N•m/221in. lbs.)
11. Install the motor assembly into the housing. Make sure the 01673 Pin fits into the line-up hole.
12. Install the 95881 O-Ring and the 55231 Guard Assembly.
13. Secure these with the 50508 Screws (4) and 95757 Washers (4). (Torque to 8.0 N•m/70 in. - lbs.)
14. To check the adjustment of the motor, secure the housing in the vise so that the spindle is pointing
up. Pull upwards on the spindle, applying ~10 -12 lbs. of force. While applying force, turn the spindle
back and forth. The rotor should turn freely without any rub. If a rub is felt, then increase load or
remove shim. Also, push downwards on the spindle, applying ~10 -12 lbs. of force. The rotor should
turn freely without any rub. If a rub is felt, then decrease load or add a shim.
15. IMPORTANT: Check spindle speed of the grinder with 90 PSIG (6.2 Bar) at the tool air inlet
WITHOUT any wheel flanging or grinding accessory mounted on the tool. – In accordance with EN
792 the no-load speed may not exceed the rated speed by more than 10%.
16. Use the 95304 Open-End Wrench (24 mm) to hold the 55224 Nut stationary. Install the 55225 Cup
Wheel Backup Flange and the abrasive wheel. Use a 5/32" hex key to secure the 55239 Retaining
Washer and the 95323 Screw.
