The Chelsea 680XSAHX-A5RA or 680XSAHXA5RA is an 8-bolt, wire/cable mechanical-shift power take-off assembly from the Chelsea 680 Series, designed specifically for higher-torque applications such as pneumatic blowers. The cast iron housing pairs with tapered cone bearings on the output shaft for long service life under sustained load. Output shaft type is 1-1/4" round with key. Shaft power output is rated at 36 HP (27 kW) at 500 RPM, 71 HP (53 kW) at 1000 RPM, and 107 HP (80 kW) at 1500 RPM. Intermittent torque is rated at 375 lb-ft (508 Nm); check application pages for actual torque ratings by installation. Compatible with Eaton/Fuller and Volvo/Mack transmissions featuring an 8-bolt PTO aperture, and includes a deep-mount housing option for Mack applications. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 680 Series is used across a range of vocational markets including aerial work platforms, snow and ice removal, fire and rescue, dump trucks, refuse vehicles, and blower and product pump applications. The 680 Series supports continuous operation with a 30% de-rating and offers four internal speed ratios across 32 output configurations. The 360-degree rotatable flange option, available across the series, provides greater flexibility for pump fitment in tight installations.
