I. New Brake Torque
New brake torque is approximately 40% less than rated design torque until the friction
and drive discs are worn in (lapped, burnished). The length of time for wear-in to occur
depends upon the application.
II. Brake Installation
A. SHAFT PREPARATION
Mach III Clutch products are bored to fit a precision plug gauge for the specified bore size and
should slide fit the mating shaft. Make certain that the shaft is free of burrs or nicks. It may be
necessary to file or sand the shaft to assure a slide fit. Never hammer the brake onto the
shaft. Hammering on the brake may cause evident damage or subtle injury that will shorten the
wear life of the unit, and will void the warranty.
(1) Apply the anti-seize (E-Z Break
®
) lubricant from the packet provided, or equivalent, to
the shaft.
(2) Insert key (customer supplied) onto the shaft.
(3) Slide brake over key on the shaft.
(4) Tighten set screws to secure the brake to the shaft.
B. MOUNTING
If the surface on which the brake will be mounted to is absolutely perpendicular to the shaft, drill
and tap holes for the number and type of clearance holes on corresponding bolt circle. Tighten
all bolts uniformly to the torque recommended for the bolt size using proper Loctite
®
(or
equivalent) compound to assure a permanent mount. If the mounting plate is not perpendicular to
the shaft, it is recommended that the brake be mounted using shoulder bolts in holes, or pins in
slots on corresponding bolt circle to allow the brake housing to float.
C. AIR LINE CONNECTION
Refer to the dimensional spec sheet for NPT size to obtain correct fitting. Install fitting using a
thread sealing compound to prevent air leakage. Connect a flexible air line to the fitting. Do not
use rigid piping. Air supply should be both filtered and regulated. Contamination in the air
supply may damage the brake.
D. FINAL INSPECTION & TESTING
Cycle the brake with the machine off to check for air leaks and to ensure proper engagement and
release. After a short run, check set screws and mounting screws.
III. Brake Operation
The maximum operating pressure should not exceed 80 PSI. Operation at pressures
greater than that required for proper function will decrease the life of the bearings.
Special Note Regarding Friction Disc Contamination:
The friction material used in this product will absorb oil, water, chemicals and other
contaminants. Depending on the type of contamination, brake may either seize up
entirely or lose torque capacity. If friction discs become contaminated, they should be
replaced. See repair kit ordering information below. If application requires exposure to
contamination consult factory for optional covers.
IV. Routine Maintenance
When installed and operated according to the preceding guidelines, Mach III Clutch
products should require little or no routine maintenance. A repair kit is available which
contains all parts subject to typical wear: friction discs, springs and O-rings.
