REPLACING ROTOR BLADES (CURVED

ROTOR MODELS)

There are two means of attaching the rotor blades to

the rotor.

The method shown in Figure 169 was used on the

CCR2000 through 1992.

Figure 169 0623-03

All Powerlite and 20” CCR models built since that time

use the style shown in Figure 170.

Rotor Blade Replacement Early CCR2000 Style

Note: Always replace BOTH blades at the same time.

One new and one worn blade will create a severe

imbalance condition that may damage the machine.

We also recommend that the scraper be replaced

whenever the rotor blades are replaced to assure

proper operation and performance.

Wear indicators were not standard at that time. The

way to determine if a rotor blade needs replacement is

to measure it as shown in (Figure 171). If the blade

measures less than 1 9/16”, it should be replaced. A

worn blade rapidly looses efficiency and throw

distance.

Removing Rotor Blade

Remove and replace one blade before starting on the

other.

Remove (8) 7/16” bolts, (4) washers, and (8) locknuts

on one blade. Note: Only the bolts on the end have

washers.

Slide the blade out from between the steel plates and

push the (8) spacer bushings out of the blade holes.

Keep the spacers for reuse.
