The Chelsea 489 Series Power Take-Off Assembly, part number 489KLAHX-A5XK or 489KLAHXA5XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and others. The one-piece cast iron housing eliminates the adapter plate found on some competing designs, cutting down potential leak paths and installation time. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); for continuous-duty applications, de-rate that figure by 30 percent and verify against the application pages for your specific setup. The output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Output power at the shaft runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, which simplifies bench service. Call us to confirm proper fit for your transmission.
