INSTALLATION

MACHINE SHAFT PREPARATION

Preparing the machine shaft prior to Pulse Generator instal-

lation is essential in providing an adequate barrier against

environ mental 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):

Remove from the M585 the four

screws which hold the end cap on the cover plate.

Remove the end cap, O-Ring, and wave spring, noting

the location of each to assist in reassembly.

SPANNER WRENCHES MUST BE USED DURING THE

FOLLOWING PROCEDURES. Using a substitute can distort

the 1

" nut and damage the unit. Do not try to remove the

⁄

" bearing locknut at any time. This locknut is factory adjusted

for optimum M585 performance.

Two spanner wrenches, which are required for M585 installa-

tion, accommodate the 1

Holding the 2

" bearing locknut, remove the 1

ter clamping nut and slide out the internal compression sleeve.

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.

If a keyway or flat exists on the shaft, provide a sealing

medium or true shaft back to round using metal putty or equal.

Return the compression sleeve to the M585 hub.

Thread the 1

" 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:

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 Guide-

lines" on the last page

for

general

re quire -

ments.

Based on the lo-

cation of the sta tionary

point and the guidelines

on page 4, attach the

places on the M585.

M585 types have an O-ring inside their hollow shafts at the mo-

tor 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

ing, 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

" to 4" onto the shaft. The end of the machine shaft must ex-

⁄

tend completely through the M585 compression sleeve and be

approximately flush with the end of the 1
