The Chelsea 9P91 (also referenced as 9-P-91) is a pressure-lubricated idler shaft designed for the Chelsea 278 Series power takeoff. As item 7 in the 278 Series illustrated parts list, this idler shaft carries a quantity-of-one fitment per unit, making it a direct service replacement within that assembly. Pressure-lube construction means the shaft relies on the PTO's pressurized lubrication circuit rather than a grease fitting, which is an important detail when selecting the correct replacement. Pro Gear and Transmission sells genuine Chelsea parts. Call us to confirm this shaft is correct for your specific 278 Series application before ordering.
