Additional Information
The Chelsea 489 Series PTO shares internal components with the Chelsea 442 Series, giving it the same 250 lb-ft torque capacity in a one-piece housing that installs faster and with fewer potential leak points. The series features strong tapered bearings rather than needle bearings for greater load-bearing capability. Twenty-seven output options are available across the series, including a 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift configurations are offered across the 489 Series lineup. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.Parts Manual: Chelsea 489 Series PTO Parts Manual (PDF) — exploded views, item numbers and the full parts breakdown for this series.
