The Chelsea 442 Series Power Take-Off Assembly, part number 442XSAHX-V3XD or 442XSAHXV3XD, is a 6-bolt mount PTO engineered for light-to-medium duty vocational truck applications. This unit carries a 0.391:1 gear ratio with an AH input gear designator, air shift actuation, and a standard mount with metric studs. The 1-1/4" round standard output shaft (XD option) is greaseable for extended service life, and the assembly runs without pressure lube (dry sump configuration). The cast iron housing and tapered cone bearings are characteristic of the 442 Series, which fits virtually all common 6-bolt transmission applications. Cross-references include S-D760, TG6S-U6812-P1BX, and WA20-06-5108, among others. Call us to confirm proper fit for your transmission.
