BRUSH MOTOR REPLACEMENT KIT
DuctMaster and TruckMaster Coaxial Spring Mount
This new version of the Brush Motor
and Mount retains all the advantages
of the original and includes some
improvements to reliability, durability,
and Debris Collection. It has more
POWER so the New DuctMasters have
a 2 position Switch for HI and Low.
Installing a new motor in a DuctMaster
without the Hi/Lo switch could run
the FIRM brush fast enough to cause
damage to older ducts. If in Doubt
about the Ducts condition, use the SOFT 12” Brush with the smaller, .021” Bristles. Contact Air Care for
questions about using the Newer Motor on existing DuctMasters or TruckMasters. 702-454-5515.
The Hoses, Motor and electrical Connections for the new version will fit previous DuctMaster Models.
KEEP THE NEW MOTOR FULLY ASSEMBLED!
First remove the OLD motor and mount from your hose:
1. Remove the screws holding the Motor Mount collar on the end of the hose and save the screws
and nuts to mount the new motor and mount. One screw also secures the internal stiffener to the
interior of the hose. (Some stiffeners are Steel, and some are Fiberglass)
2. Cut the 3 wires for the motor leaving enough cord to crimp (or solder) the wires to the new motor
wires. All 3 wires will need to be the same length for this new Motor Connection.
3. You will no longer need any of the parts in the original motor assembly unless you are returning it
to Air-Care with an RMA for warranty evaluation.
1. Be sure you have all the parts for the installation.
a. Your original Screws, 10-32 x 5/8” long machine screws,
b. 10-32 Hex Nuts with built in Lock Washers.
c. Metal or Fiberglass Stiffener (if it was on the original hose)
2. Remove the outer insulation from the black power cord in the hose to expose the 3 insulated
motor wires about 2 inches long.
Installing the NEW Motor Assembly.
