The Muncie Power Products 8405/6A Series Power Take-Off (PTO) is a heavy-duty, mechanical mechanical-shift (air-engaged) PTO. Built with a rugged, one-piece ductile iron body, this series integrates the 8-bolt mounting pad, direct pump flange, and air shift cylinder into a single rigid casting. It is specifically engineered to handle intense structural vibrations at an economical price point.
One-Piece Single Casting: Combines the housing, air shift cylinder, and pump flange into one continuous block. This eliminates standard external seam joints, cutting down on structural deflection and significantly reducing the chance of oil leaks.
TG8S Replacement Profile: Specifically designed with internal ratios equivalent to Muncie's popular TG8S-U6807, 08, and 09 configurations. This allows fleets to seamlessly upgrade or substitute existing gear packages.
Integrated Inspection Port: Built with an easily accessible viewing cover on the side. This allows technicians to perform flawless backlash clearance adjustments using a dial indicator without removing the unit from the truck frame.
High Vibration Resilience: The heavy ductile iron composition absorbs harsh chassis vibrations. This makes it highly optimized for severe-duty fields like heavy vocational trucking and demolition work.

| Speed Ratio | Intermittent Power @ 1,000 RPM (HP) | Intermittent Torque (lb-ft) | Continuous Torque (lb-ft) | Intermittent Power @ 1,000 RPM (kW) | Intermittent Torque (Nm) | Continuous Torque (Nm) |
|---|---|---|---|---|---|---|
| 07 | 44 | 230 | 161 | 33 | 312 | 218 |
| 08 | 44 | 230 | 161 | 33 | 312 | 218 |

Applications
Fire and Rescue Vehicles : Provides immediate, high-horsepower engagement under load to drive high-volume water pumps and aerial ladders.
Dump Trucks & Trailers : Operates the large hydraulic cylinders needed to raise and lower heavy dump beds quickly and safely.
Cranes & Boom Trucks : Supplies smooth, continuous hydraulic flow for precise control of telescopic booms and outriggers.
Vacuum & Sewer Cleaner Trucks : Runs high-capacity vacuum pumps and high-pressure water jetters for municipal and industrial cleanup.
Fuel & Chemical Tankers : Drives product pumps to safely offload bulk liquids and hazardous materials.


8405/6A PTO are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Direct pump mounts: It natively supports direct-coupling small to mid-sized gear pumps via standard SAE "B" or SAE "BB" 2-bolt/4-bolt rotatable flanges.
Keyed shafts: It can also be optioned as code "B" featuring a 1-1/4" round keyed output shaft to easily drive remote yoke u-joints.
Gear tooth profiling: The 8405A uses a 6-pitch, 20-degree pressure angle spur gear setup, while the 8406A utilizes a 6.48-pitch, 17.5-degree gear layout.
Mesh verification: You must check your transmission's exact driver gear pitch suffix to avoid matching the wrong tooth contour, which instantly shatters internal components.
Metric mounting kit: Standard "A" models ship with standard Imperial mounting fasteners.
Import specifications: Opting for the "B" package means the box includes a dedicated metric stud and nut mounting kit designed for international transmission castings.
Stationary engagement only: No. Because it relies on a sliding mechanical collar rather than a smooth internal wet clutch pack, it must never be hot-shifted.
Safe sequence: The truck must be fully stopped, the parking brake set, and the clutch pedal depressed (or automatic placed in neutral) before hitting the air switch.
Short-cycle dumps: It is built for intermittent tasks that require reliable, brute-force raw mechanical power.
