AIR SUSPENSION PUMP AND GAUGE
HD-34633
1

The motorcycle features air-adjustable rear suspension. Air pressure in the rear shock absorbers may be adjusted to suit load requirements, riding style and personal comfort.
NOTICE
Do not exceed maximum air pressure for suspension. Air components fill rapidly. Therefore, use low air line pressure. Failure to do so can result in possible damage to components. (00165b)
WARNING
Use caution when bleeding air from the suspension. Moisture combined with lubricant may leak onto the rear wheel, tire and/or brake components and adversely affect traction, which could result in death or serious injury. (00084a)
  1. Remove the left saddlebag. See Controls and Indicators → Saddlebags: Police Models.
  2. See Figure 1. Remove the cap from the air valve located behind the shock absorber on the left side of the vehicle.
    3. NOTE
    • Always add 21–35 kPa (3–5 psi) to the existing pressure before releasing air from the system to prevent oil for exiting the air valve. NEVER exceed 345 kPa (50 psi).
    • Do not exceed maximum GVWR or GAWR.
  3. Refer to Table 1. Attach AIR SUSPENSION PUMP AND GAUGE (Part Number:HD-34633) to the air valve. Fill or release air from the shock absorber to the pressure specified for your model motorcycle and load.
    4. NOTE
    The specified pressures are recommended starting points. Adjust pressure to suit load conditions, riding style and comfort desired. Less pressure does not necessarily result in a softer ride. Using pressures outside the recommended loading range will result in a reduction of available suspension travel and reduced rider comfort.
  4. Install cap on air valve and install left saddlebag.
