Rotor Cover Rollers Removal (Figure 20)
1. Remove the screws and clamps that secure the rollers to the rotor.
2. Lift out the rollers and pins. Check for wear and smoothness of operation.
On certain type meters, blade blocks rather than rotor cover rollers are used. Blocks should be
Flat. If grooved, they may be turned over and reused. The rotor cover and rotor are mated parts.
If taken apart, they should not be exchanged with another meter or replaced individually.
3. To separate the cover and rotor, pry up (to prevent damaging edge of rotor) at the openings
provided, Figure 21.
4. Lift off the cover. Note position of locating pin and hole to assure proper positioning during
reassembly.
Mark the position of the blades in relation to the rotor slots before proceeding with
disassembly (Figure 22). Note the different blade and rotor bearings for standard and
tungsten carbide meter versions (See Figure 22A).
5. Remove the lower rotor bearing if it is still in place.
