ACCU-TURN 8944 MULTI-SPEED BRAKE LATHE
MOUNTING AND MACHINING PROCEDURES
Inspection of Brake Drums, Disc Rotors & Flywheels Before
Machining
IMPORTANT: The maximum amount of metal removed from the
finished workpiece should never exceed the manufacturer's
specifications. It is dangerous to operate a vehicle with a drum,
rotor or flywheel which has had more material removed than is
allowed. Proper operation cannot be established if these
specifications have been exceeded. ACCU Industries recommends that
each workpiece be checked for size before mounting on the lathe and
after machining.
Mounting Hubless Drums or Rotors
1.
Clean and check all surfaces for flatness that will come in
contact with centering cones and/or bell clamps to ensure
solid mounting.
2.
Cleaning and properly mounting the drum or rotor prior to
machining will ensure a minimum of stock removal, better
surface finish and optimum braking efficiency.
3.
Excessive run out or wobble of the drum or rotor after it has
been properly cleaned and mounted on the arbor may indicate
severe damage to the drum or rotor. These drums or rotors
should not be used for further service.
