The Remanufacturing Process Behind the Volvo 22419 Transmission

Heavy equipment like Volvo articulated haulers rely on powerful, reliable drivetrains to operate in the most demanding conditions. At the heart of these machines is the 22419 transmission—a robust automatic powershift transmission designed to handle tough off-road environments. Over time, even the most durable transmission requires rebuilding, and remanufacturing the Volvo 22419 is a detailed process that restores it to like-new performance.

Understanding the Volvo 22419 Transmission

Found in machines like the Volvo A35 and A40 haulers, the 22419 transmission is a critical component in Volvo's powertrain system. It's engineered to deliver smooth, reliable shifting under heavy load and in rough terrain. Paired with components like the Volvo 22737 drop box, this transmission enables full-time all-wheel drive and high torque output, making it a cornerstone of Volvo’s articulated hauler performance.

Step-by-Step: How the 22419 Is Remanufactured

Initial Inspection and Evaluation

The remanufacturing process begins with a thorough assessment. The unit is identified by its model and serial number, then visually inspected for damage. Fluids are drained and analyzed for signs of excessive wear or internal failure.

Complete Disassembly

Every component of the transmission is removed, including clutch packs, gear sets, shafts, valve body, and torque converter. This complete teardown ensures no damaged or worn part is left behind.

Cleaning and Surface Prep

Once disassembled, all parts are cleaned using industrial-grade methods such as hot tank washing or ultrasonic cleaning. Housing and casings may be media blasted to remove scale and corrosion from non-critical surfaces.

Detailed Inspection

Using precision tools, technicians check tolerances on gears, shafts, bushings, and bearings. Clutch plate thickness is measured, and valve body components are tested for function. Advanced methods such as magnaflux crack detection ensure structural integrity.

Replacement of Worn Components

Any part found to be outside of OEM specification is replaced. This includes all clutch plates and steels, seals, gaskets, bushings, and bearings. In some cases, upgrades are installed to improve durability beyond original factory standards.

Reassembly to OEM Specs

With all components cleaned, inspected, and replaced as necessary, the transmission is carefully reassembled. Torque settings and clearances are strictly followed to ensure optimal function. New solenoids or electronic components may also be installed.

Dyno Testing

When available, the transmission is placed on a test bench and run through a series of load and shift simulations. This confirms that all gear ranges are working properly and that hydraulic pressures, shift timing, and operating temperatures are within specification.

Final Inspection and Finishing Touches

Before shipping, the remanufactured transmission undergoes a final inspection. It’s sealed, painted, and tagged with a serial number and remanufacture date. A full inspection sheet or dyno test report is often included.

Bringing Equipment Back to Life

Remanufacturing a Volvo 22419 transmission isn’t just about replacing worn parts—it’s about restoring performance, reliability, and value. Whether for a single unit or an entire fleet of articulated haulers, a properly remanufactured transmission can extend the life of heavy equipment and reduce downtime significantly.

For operations that depend on Volvo construction equipment, understanding the depth and precision of the remanufacturing process is key to maintaining productivity and efficiency in the field.
