WARNING — Outer flange
The outer flange MUST be in place to prevent the puller
assembly and inner flange from flying off when the taper
breaks loose. Injury or equipment damage could
otherwise result.
WARNING
If unfamilar with this operation, seek assistance or
training from someone that is familar with this operation.
Because of the tapered fit between the blade flange
and blade shaft, 5-10 tons of force is required to release
the inner flange from the blade shaft. Both parts and
tools can become dangerous projectiles if instructions
are not followed properly.
Removing the Inner Blade Flange
1. With the outer blade flange in place, remove the blade
mounting bolt (Figure 53, item 6).
2. While the 3 perimeter bolts (item 4) hold the two puller
plates together, slide the horseshoe plate (item 2) of
the flange puller behind the shaft side of the inner
flange.
3. Tighten the center puller bolt (item 5) to remove the
inner flange from the blade shaft.

puller bolt is tightened, lightly tap on the
center puller bolt to allow the flange to break
free from the shaft.
