Every axle undergoes 100% dimensional inspection, gear contact pattern testing, and run‑out verification to guarantee interchangeability with OEM specifications.
The 800391344 centre axle features a high‑durability epoxy powder coat finish that provides excellent corrosion resistance, with over 500 hours of salt spray protection.
The shafts are induction‑hardened to provide outstanding wear resistance and long service life in high‑load driveline applications.
The hypoid gears are case‑hardened to 58‑62 HRC, providing a hard, wear‑resistant surface while maintaining a tough core for shock resistance.
The housing is phosphated before painting, ensuring excellent paint adhesion and corrosion protection.
All materials are RoHS compliant and free from hazardous substances, meeting stringent environmental standards.
The combination of premium materials and precise manufacturing makes this axle ideal for the most demanding off‑highway applications.
The 800391344 is designed for professional installation using heavy‑duty workshop equipment, requiring proper lifting and alignment tools.
To install, first support the vehicle safely and remove the old axle. Clean the mounting surfaces on the chassis and suspension arms.
Position the new axle under the chassis and align the mounting bolts, torquing to the recommended values as specified in the service manual.
Connect the driveline, brake lines, and suspension components, ensuring all connections are secure and properly routed.
After installation, fill the axle with the recommended lubricant (SAE 80W‑90 or equivalent) and bleed the brakes.
Inspect the axle for leaks and test operation before returning the machine to service.
Investing in the 800391344 Centre Axle delivers significant long‑term savings by preventing driveline failures, reducing tyre wear, and minimising downtime.
