The Rotor and Blade Assembly uses Shims to set the
Rotor to Shelf clearance. Set the Shims aside for use
when reassembling. Depending on part replacement,
Shims may need to be added or removed (Figure 20).
To disassemble the Rotor and Blade Assembly, the twelve
Blade Retainer Bolts (4mm) will need to be removed.
Once the bolts are removed, the Blade Retainer can be
removed (Figure 21).
Inspect the magnetic coupling on the shaft. Only remove
the coupling if it’s broken or damaged. There’s a Spring
Washer at the base of the Cover Shaft. Remove it and
set it aside for reassembly. Also inspect the Spring
Washer for damage and replace it, if necessary.
To remove the Rotor Cover there are four threaded holes
in the Rotor Cover; one on each segment. Install four of
the screws to act as Jacking Screws.
Once the screws are installed, turn them clockwise
evenly. This will lift the cover off of the Rotor (Figure 22).
After the Rotor Cover is removed, the Blades, Cam and
Shaft are exposed. Turn the shaft so that half of the
upper Blade Paddle is exposed on both sides of the
Rotor. The Upper Blade can be removed. Remove the
Shaft and then the Lower Blade (Figure 23).
Note:
Mark the slot, along with the Upper and Lower Rotor and the
Blade that corresponds to that slot with a permanent marker. If the
Blades are to be reused, they must be installed in the same position
they were removed from (top, bottom and slot). Complete this for
both Blades.
