ISUZU POWER TAKE-OFFS (HAYNEKS OA SERIES)

The OA Series represents our high-output line for Isuzu vehicles. These PTOs are built with reinforced housings and precision-cut gears to handle the rigorous demands of hydraulic tipping and pumping systems while maintaining a low-profile fit for modern chassis.

Compatibility is based on the gearbox model. The Hayneks OA Series supports common Isuzu transmissions such as the MYY and MZZ series. Always check the transmission plate on the side of your gearbox before ordering to ensure the spline count and gear pitch match perfectly.

Our Isuzu Power Take-Offs are designed for versatility, with torque capacities generally ranging from 250 Nm to 450 Nm. This allows them to power a variety of equipment, from light delivery tippers to specialized municipal waste compactors.

To ensure operator comfort and system longevity, most OA Series units use Pneumatic Engagement. This allows for a clean shift from the cabin using an air switch. For older Isuzu models or those without air systems, vacuum or cable-operated versions are available.

Yes. The Hayneks Isuzu PTOs come with standard ISO 4-bolt or UNI 3-bolt output configurations. This direct-mount design eliminates the need for drive shafts between the PTO and the pump, reducing vibration and maintenance points.

The Gear Ratio (the speed of the PTO output relative to engine speed) is vital for pump performance. If the ratio is too low, the hydraulic system will be sluggish; if too high, it may damage the pump. Hayneks offers optimized ratios to match Isuzu engine power curves.

These units are industry standards for Logistics, Construction, and Waste Management. They are the primary power source for tipper bodies, recovery truck winches, and small-to-medium hydraulic cranes mounted on Isuzu chassis.

Longevity depends on Lubrication and Backlash. Ensure the PTO is properly shimmed during installation to prevent gear whining. Regularly check the transmission oil level and inspect air lines for any signs of cracking or leakage.

Every Hayneks Isuzu OA Series unit includes a complete Mounting Kit. This includes high-tensile studs, nuts, and a set of gaskets. Using the correct thickness of gaskets is essential for setting the proper gear clearance during installation.

While designed for high durability, most transmission-mounted PTOs are intended for intermittent use. For Heavy-Duty applications, ensure your hydraulic system includes proper oil cooling to prevent heat transfer back into the Isuzu gearbox.
