Description
World American WA20-08-7000 is an 8-bolt SAE-mount air-shift power take off (PTO) assembly that replaces Chelsea 489KFAHX-V3AK / V3RA / V3RB / V3SQ / V3XK / V3XQ and the equivalent Muncie TG8 series. The PTO bolts to a transmission’s 8-bolt opening (typically Eaton-Fuller, Allison, or Mack) and uses dash-air pressure at the shift cylinder to engage internal clutch teeth, driving auxiliary gear-pump or driveshaft loads on dump, refuse, wet-kit, and winch trucks.

Applications
This PTO fits 8-bolt SAE PTO openings on heavy-duty truck transmissions used in vocational service:
- Dump truck wet-kit hydraulic systems
- Refuse / sanitation truck packer drives
- Winch and recovery truck driveshaft loads
- Auxiliary hydraulic-pump applications on Class 7-8 chassis
Verify the transmission’s PTO opening, output rotation (CW vs CCW), output flange or shaft style, and torque rating before ordering. PTO compatibility depends on the transmission make and model, not just the bolt pattern.
