The Chelsea 489 Series Power Take-Off Assembly, part number 489ZHDAX-P5AF or 489ZHDAXP5AF, mounts directly to an 8-bolt transmission opening with a one-piece cast iron housing that eliminates the adapter plate and reduces potential leak paths. This unit uses a 12V electric/air shift type and delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the 442 Series. Output is through an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. The 489 Series is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM.
