Brush Motor Replacement Kit for
DuctMaster and TruckMaster
Updated 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.
This motor and Hose mount will replace all previous motors and mounts.
KEEP THE NEW MOTOR FULLY ASSEMBLED!
First remove the OLD motor and mount from your hose:
1. Remove the screws holding the metal collar on the end of the hose and save the screws and
nuts to mount the new motor and mount.
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.
Installing the NEW Motor Assembly.
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.
2. Remove the outer insulation from the black power cord in the hose to expose the 3
insulated motor wires about 2 inches long.
3. Strip the insulation off of all 3 wires about ½” back from the ends.
4. Slide the black Shrink Tubing over the cable. It will be slid over the new connections after
the wires are connected.
5. Slide the 3 pieces of shrink tubing over each of the motor wires. The connections can be
made by Crimping the new connectors or soldering them. If you are planning to solder the
connections, be sure the blue shrink tubing is far enough away from the heated ends to
prevent it from shrinking prematurely.
6. The wires may be different colors from the Motor than the ones from the hose cable. The
order is not important, the brush will operate with any combination of wires, but it may turn
in the opposite direction in some cases, but will still reverse as before.
7. Each of the 3 wires from the hose can now be inserted into the Crimp connectors on the
new motor. Try to twist the wires tight enough so that all of the strands go into the silver
