Blade Collar Removal/Installation

Correct removal or installation of the Inner Blade Collar or Flange requires the

Collar Puller (option Part Number 18503) shown in Figure 31.

WARNING

Follow instructions closely to prevent injury from flying Blade Collars!

Because of the tapered fit between Blade Collar and Blade Shaft,

5-10 tons of force is needed to release the inner collar. Parts and

tools can become dangerous projectiles if instructions are not

followed properly.

Fig. 29 — Using the Collar Puller

Removing the Inner Blade Collar

With the Outer Blade Collar in place, and the Blade Mounting Bolt loosened

approximately ¼”:

1. While the three perimeter bolts hold the two Puller Plates together, slide

the Horseshoe Plate of the Collar Puller behind the (Shaft) side of the

Inner Collar as shown above.

2. Tighten the center Puller bolt to remove the Inner Collar from the Blade

Shaft.

♦ Having the Outer Collar in place prevents the Puller and Inner Collar from flying

off when the taper breaks loose, and causing injury!

♦ If the Inner Collar does not readily come free from the tapered Blade

Shaft, lightly tap on the central Puller bolt. This should cause the collar to

break free from the shaft.
