The Chelsea 880 Series Power Take-Off Assembly, part number 880XJAHX-V5XK or 880XJAHXV5XK, is a heavy-duty 8-bolt PTO designed for high-torque, high-cycle applications including fire trucks, bulk haulers, oil field equipment, large recovery trucks, and aerial units. It uses a lever mechanical shift and delivers an intermittent torque rating of up to 500 lb-ft (678 Nm) - check application pages for actual ratings. The output shaft is a 1-1/2"-10T spline paired with a 1410 companion flange, supporting shaft power of 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible transmission families include Volvo/Mack, Allison, and Eaton/Fuller. A removable shift cover makes backlash adjustment straightforward during installation. Available from Pro Gear and Transmission - call us to confirm proper fit for your transmission.
The Chelsea 880 Series is designed for demanding on-highway and off-highway work: bulk haulers, winch systems, fire trucks, oil field equipment, aerial units, and large truck recovery. Constant mesh input gears support both high-speed and low-speed, high-torque duty cycles. Tapered cone bearings provide load-bearing capability suited to these applications. The standard shift is lever-controlled; the series also supports an optional air control shift on applicable configurations. For installation reference, Parker publishes the 880 Series Owner's Manual (HY25-2880-M1_US), the 880 Series Parts List, and the Chelsea Service Manual (HY25-6880-M1/US).
