MAINTENANCE

Installing the Inner Blade Flange

1. Ensure that the tapered portion of the blade shaft and the

inner blade flange are clean and free of burrs or indentations.

Clean and repair as necessary. See Figure 54.

2. Ensure the drive key is in place (Figure 54, item 6).

3. Slide the inner flange (item 5) onto the tapered portion

of the blade shaft (item 7).

4. Install the outer blade flange (item 3), flange bushing

(item 2), and mounting bolt (item 1).

5. Tighten with a 1/2" impact wrench to seat the tapered

surfaces of the inner flange and blade shaft.

CAUTION — Do not use lubricant

DO NOT use lubricant of any kind. Lubricant prevents

the tapered surface of the flange and shaft from mating

properly.

6. Loosen the mounting bolt and remove the outer flange

7. Inspect the inner flange to ensure the proper seating

of the tapered fit. The inner flange should be seated

between .030" and 0.0" (flush) to the end of the blade

shaft. See Figure 55.

8. Test to ensure that the inner flange does not wobble

when rotated. Use a dial indicator on the face of the

flange (Figure 55, Item 4). Maximum tolerance is .002"

runout on the face of the flange when rotated.
