The Chelsea 489 Series Power Take-Off, part number 489ZQITX-A5RB or 489ZQITXA5RB, mounts directly to an 8-bolt transmission opening without an adapter plate, reducing potential leak paths. Its one-piece cast iron housing delivers the same 250 lb-ft intermittent torque capacity as the 442 Series. Output shaft is a 7/8" 13-tooth SAE B shaft on a rotatable SAE B 4-bolt flange. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. For continuous-duty applications, derate the intermittent torque rating by 30% and confirm your actual rating on the application pages. Strong tapered bearings replace needle bearings for greater load capacity. Call us to confirm proper fit for your transmission.
