INSTALLATION
MACHINE SHAFT PREPARATION
Preparing the machine shaft prior to Pulse Generator
installation is essential in providing an adequate barrier against
environmental contamination. In some cases, a separate stub
shaft (1.125" D x 4.5" long) will be installed on the motor. To
prepare the machine shaft that the M585 is to be installed on,
conduct the following procedures (see figures):
1. Remove from the M585 the four 1⁄4-20 UNC machine
screws which hold the end cap on the cover plate.
2. Remove the end cap, O-Ring, and wave spring, noting
the location of each to assist in reassembly.
CAUTION
SPANNER WRENCHES MUST BE USED DURING THE
FOLLOWING PROCEDURES. Using a substitute can distort
the 13⁄4" nut and damage the unit. Do not try to remove the
21⁄2" bearing locknut at any time. This locknut is factory adjusted
for optimum M585 performance.
NOTE
Two spanner wrenches, which are required for M585
installation, accommodate the 13⁄4" and 21⁄2" nuts found under
the cap.
3. Holding the 21⁄2" bearing locknut, remove the 13⁄4"
diameter clamping nut and slide out the internal compression
sleeve.
4. Verify that the compression sleeve can be installed by
hand on the shaft where the unit is to be installed. File any
burrs that obstruct sleeve installation and lightly oil the shaft.
5. If a keyway or flat exists on the shaft, provide a sealing
medium or true shaft back to round using metal putty or equal.
6. Return the compression sleeve to the M585 hub.
7. Thread the 13⁄4" clamping nut onto the M585 by hand until
resistance is felt. DO NOT TIGHTEN AT THIS TIME.
PULSE GENERATOR INSTALLATION
Installing the M585 and Anti-Rotation Arm:
1. The free end of the Anti-Rotation Arm must be secured
by the customer to a
stationary member such
as the floor or machine
frame. Refer to “Anti-
Rotation Arm Mounting
Guidelines” on the last
page for general re-
quirements.
2. Based on the
location of the sta-
tionary point and the
guidelines on page 4,
attach the 1⁄4" thick
mounting board pro-
vided to one of five
places on the M585.
Use two 1⁄4-20 UNC by
3⁄4" long machine screws
provided.
3. Ensure that the machine shaft is lightly oiled. Apacket of
silicone grease is provided to lubricate the following shaft seals:
First, ALL M585 types have an O-ring inside their hollow shafts
at the motor end. In addition, in THRU SHAFT types, the
clamping nut has an O-ring on the inside, plus the outside of the
clamping nut requires lubrication for the radial lip seal per step
8b. Slide the M585 onto the machine shaft, mounting board
first. Ideally, the M585 housing will be 1⁄2" to 1" from the motor or
machine housing, but this may vary depending on the machine
profile and the anti-rotation arm clearance requirements.
Consider shaft end float when positioning the M585.
4a. FOR STUB SHAFT APPLICATIONS, place the M585
31⁄4" to 4" onto the shaft. The end of the machine shaft must
extend completely through the M585 compression sleeve and
be approximately flush with the end of the 13⁄4" clamping nut.
4b. FOR THRU SHAFT APPLICATIONS, position the M585
as required.
5. Attach free end of the Anti-Rotation Arm to the
1⁄4" mounting board using the shoulder bolt provided.
6. Remove 13⁄4" clamping nut and apply liquid thread locker
to the threads. (Locktite grade 242, supplied, should be used in
most applications.) NOTE
Where thread locker has been used, additional force is required
for M585 removal.
7. Replace 13⁄4" clamping nut and tighten so the gap is less
than or equal to 0.09", as shown in CLAMPING NUT sketch
(approx. 15-20 ft-lbs), holding the 21⁄2" bearing locknut in place.
Spanner wrenches are required for this operation.
8a. FOR STUB SHAFT INSTALLATIONS, replace the end
cap with the wave spring (loading spring) against the bearing
and the O-ring located in the cap groove. Secure the end cap
with the four 1⁄4-20 UNC machine screws previously removed.
Apply the supplied grade 242 Locktite to the screws when
assembling.
8b. FOR THRU SHAFT APPLICATIONS, prior to replacing
the end cap per step 8a, apply a small amount of silicone
grease (provided) to the seal surface on the 13⁄4" clamping nut.
The radial lip seal in the end cap will seal on this surface.
