The Chelsea 489 Series Power Take-Off, part number 489XFAHX-A5AZ or 489XFAHXA5AZ, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission face, eliminating the adapter plate that creates an extra potential leak path. This unit delivers up to 250 lb-ft intermittent torque and an output of 46-55 HP, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. The 1-1/4" round output shaft accepts a keyed connection, and shift is accomplished via wire/cable mechanical linkage. Strong tapered bearings replace needle bearings for greater load-carrying capability. Internal parts are shared with the 442 Series. Call us to confirm proper fit for your application.
The Chelsea 489 Series is suited for vocational and municipal equipment including utility trucks, dump trucks, snow and ice removal vehicles, and fire and rescue apparatus. Eleven internal speed ratios are available across the 489 Series product line, and the design accommodates up to 27 output configurations including a 360-degree rotatable flange. Continuous torque ratings are de-rated 30% from intermittent ratings; consult Chelsea application pages for the actual rating for a specific configuration. For service documentation, Parker Chelsea publishes the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
