The Chelsea 880XBAKP-M4AZ is an 880 Series Power Take-Off built for heavy-duty, high-torque applications. The 880 Series fits most manual transmissions with an 8-bolt aperture and is engineered for constant mesh input with up to 500 lb-ft intermittent torque. Output options across the 880 family include SAE B, SAE BB, and SAE C pump flanges as well as driveline configurations. The cast iron housing and tapered cone bearings handle the demands of oil field equipment, fire trucks, bulk haulers, large tow and recovery trucks, and aerial applications. Shift is accomplished via standard lever control, with an optional air control shift available. The removable shift cover simplifies backlash adjustment. Available from Pro Gear and Transmission.
