The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-S3RB or 489XFAHXS3RB, mounts directly to 8-bolt transmission openings on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates a potential leak path that adapter-plate designs introduce. This unit uses an air shift and delivers up to 250 lb-ft (339 Nm) intermittent torque, consistent with the 442 Series rating. The rotatable SAE B 4-bolt flange with a 7/8" 13-tooth SAE B shaft accepts a wide range of pump drives. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your transmission application.
