The high pressure blower supplies air to cool the bike’s engine.
The blower extension arm assembly comes ready to mount to the tire carriage on the
dyno. However, if you have a power carriage installed on your dyno, you will need to
make adjustments to the extension arm assembly before mounting the assembly to
the dyno. Refer to “Modifying the Extension Arm Assembly (For Power Carriage
Only)” on page A-6.
To prevent possible injury, disconnect the battery before performing any dyno
maintenance or installing any optional accessory.
MODIFYING THE TIRE STOP
Older dynos may not have the four holes on the tire stop needed to mount the
extension arm assembly; you will need to modify the tire stop before continuing with
the blower installation instructions. Refer to Figure A-1 for hole size and placement.

MODIFYING THE EXTENSION ARM ASSEMBLY (FOR POWER CARRIAGE ONLY)
When the blower assemblies are used with a power carriage, the following
modifications must be made to the extension arm assembly before mounting the
extension arm assembly to the dyno.
Note: These modifications should be made only when a power carriage is
installed.
1 Remove the four hand knobs from the extension arms.
2 Remove arm A, including the poly washer, and set aside.
3 Remove the bolt, lock washer, fl at washer, and spacer securing arm B to the main
bracket, including the poly washer, and set aside.
Note: Arm B is the only arm with a threaded pin.
