the rotor to engage the cams. Tighten to 9-10 ft-lb
(12.2-13.5 n-m). Total cam screw rotation will be less than
one turn.
END-OF-SHAFT APPLICATIONS
(Rotors EF-E9, HF-H9)
See Table 2 for part numbers:
1. Verify that the shaft projection from the C-face of the motor is
0.400” [10.2mm]. Apply anti-seize to the shaft.
1a. GE CD180-320 style kits (-EF) require a roll pin (included) .
Install the pin in the rotor first, then position the rotor on the
shaft. Lightly tap into place.
2. Apply threadlocker to the bolt(s); use the supplied washer(s)
and tighten.
THROUGH SHAFT APPLICATIONS
(Rotors TA-T9, CA-C9, MF-MZ, KA-K9)
See Table 3 for part numbers:
1. The through-shaft must project at least 1.5” [38.1mm] from
the accessory mounting face. If it is greater than 2” [50.80mm]
long, use the outboard through-shaft cover, detailed in Figure 4.
2. Slide the rotor on the shaft (option “B” or “T”), ensuring the
rotor label “this side out” is away from the motor. The space
between the mounting face and the rotor must be set to
0.584” [14.83mm], as shown in Figure 2. Use Avtron gauges
(A35226 or A25355) or housing alignment grooves as shown
in Figure 5 to verify position. (Note: if optional inboard seal or
shield plate is used, gage the rotor location from the seal
shield plates. See Figure 3.)
2a. If using a set screw rotor (TA-T6), apply threadlocker to the
set screws (2) and tighten to 25 in-lbs.
2b. If using a cam screw rotor (CA-C3), threadlocker is pre-
applied. Turn the cam screw(s) of the rotor in the directions
shown on the rotor to engage the cams. Tighten to 9-10 ft-lb
(12.3- 13.5 n-m). Total cam screw rotation will be less
than one turn.
STATOR HOUSING INSTALLATION
ROTOR INSTALLATION
Use the dial indicator gauge to ensure motor shaft runout (TIR) does
not exceed (0.004”) [0.10mm]. Apply anti-seize compound to the shaft.
CAUTION
Do not strike the encoder or rotor at any time. Damage
will result and the warranty will be void. At installation,
clean and remove paint and burrs from motor shaft and
mounting face. Apply anti-seize compound (supplied) to
each EXCEPT CAM SCREW ROTORS.
UNIVERSAL END-OF-SHAFT APPLICATIONS:
(Rotors GF-G9, UF-U9, QF-Q9)
See Table 2 for part numbers.
1. Verify the shaft projection from the C-face of the motor is
0.400”.
2. GE CD180-320 style kits (-UF) require a roll pin (included) to be
inserted into the shaft hole before installation of the stub shaft
adapter.
2a. Install the shaft adapter on the motor using the bolts,
threadlocker and washers provided.
3. Verify the stub shaft runout/wobble is less than 0.004” TIR.
(0.001” is ideal). Use a dead blow hammer or shims (provided)
to true the shaft as needed.
4. Slide the rotor onto the stub shaft. The space between the
mounting face and the magnetic strip of the rotor must be set
to 0.584”, as shown in Figure 2. Use Avtron gauges (A25355 or
A35226) or use housing alignment grooves as shown in Figure
5 to verify position.
NOTE
If optional inboard seal plate and/or magnetic shield is used,
gage the rotor location from the shield/seal plate(s). Ensure
the rotor label marked “this side out” is facing away from
the motor.
4a. For rotors UN, UP, and UQ ensure the counter bored holes
on the motor side of the rotor line up with the bolt heads
used to mount the adapter. This will permit proper rotor axial
positioning.
5. Turn the cam screws of the rotor in the directions shown on
