Additional Information

The Chelsea 524 Series uses a two-gear design in a compact housing that helps eliminate clearance issues common with side-mount installations. Three speed ratios are available within the series to match application torque and speed requirements. Six shift options are integrated directly into the PTO housing, reducing external plumbing and saving space. Two direct-mount pump output flanges are included for hydraulic pump attachment. A quick-assembly sealed bayonet connector is used for the indicator switch, simplifying installation and service. Typical applications for this series include aerial, fire, refuse, tipper, and sewer and sanitation trucks operating in on-highway and vocational service.
