The Chelsea 489 Series Power Take-Off Assembly, part number 489ZHDAX-V3RB or 489ZHDAXV3RB, is an 8-bolt PTO built for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with an application-specific rating of 250 lb-ft (check application pages for confirmed figures). Shaft output runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit features a 1-1/4" round output shaft with key, wire/cable mechanical shift, and tapered bearings instead of needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series offers 27 output options, including a 360-degree rotatable flange, and 11 internal speed ratios. Common internal parts with the 442 Series simplify parts inventory for shops running multiple Chelsea PTO models. Typical applications include utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles.
