The Chelsea 442KRJKX-P3RK or 442KRJKXP3RK is a 442 Series Power Take-Off built for 6-bolt transmission applications. The cast iron housing and tapered cone bearings on the output shaft are defining features of the 442 Series, delivering a class-leading torque rating and extended service life in light-to-medium duty vocational work. The series supports wire/cable or mechanical shift and a round output shaft with a 1-1/4" key. Output flanges are rotatable for improved clearance, and the output shaft is greaseable for extended service intervals. Typical applications within the 442 Series include dump trucks, tow trucks, service trucks, and aerial trucks.
