To prepare the motor facing and shaft for installation, perform the following steps. See Figure 4.
1. Clean outer rim and surface of motor facing and shaft of paint, grease, dirt, and other debris where RIM Tach 1250 unit
contracts motor or accessory. Also ensure that mating surfaces have not been damaged and that unit will fit squarely on
motor.
Ensure there is no paint, burrs, protrusions, or deformations on the motor facing or shaft. If the
enclosure does not fit squarely on the motor facing, the alignment between the sensor module
and the magnetic pulse wheel may be degraded.
2. Apply a thin layer of corrosion preventative or oil to motor facing and shaft to aid assembly.
The pulse wheel must be well attached during rapid acceleration or deceleration of the shaft.
The installer may elect to drill the set screw holes before installing the enclosure. Alternatively,
the installer may elect to install the enclosure, measure, then remove the enclosure before
drilling. Continue with Steps 3 through 5 if electing to predrill set screw holes. If not, proceed to
2.2.2 and continue with the installation procedure.
3. The pulse wheel assembly uses two set screws to hold the unit in place. These holes are at 90 degrees to each other and
located 2.316 ± 0.005 inches from the motor facing.
4. Locate three holes using appropriate measuring equipment.
5. Use standard 17/64 inch bit to drill a hole that is 0.09 to 0.11 inches deep from the tangent point of the shaft
(point of first contact of the drill to the shaft) to the bottom of the hole. Do this for both holes.
