A Volvo A25C articulated dump truck purchased at auction revealed missing teeth on the planetary gear, requiring a full replacement and prompting a search for salvage parts and cost-effective repair strategies. This situation highlights the challenges and decisions faced by owners restoring older ADTs for active use.
Volvo A25C Overview
The Volvo A25C is part of Volvo Construction Equipment’s long-running articulated hauler series, introduced in the 1990s. Designed for hauling heavy loads across rough terrain, the A25C features a 6x6 drivetrain, hydraulic suspension, and a payload capacity of approximately 25 metric tons. It is powered by a Volvo TD 73 KCE diesel engine and equipped with a fully automatic transmission and planetary final drives.
Volvo CE, founded in Sweden in 1832 and a division of the Volvo Group, pioneered the articulated hauler concept in the 1960s. The A-series trucks have been widely adopted in mining, quarrying, and large-scale earthmoving projects. The A25C was succeeded by newer models like the A25D and A25F, but many C-series units remain in service due to their robust design.
Terminology Notes
After acquiring the A25C at auction, the new owner addressed several known issues:
Parts Sourcing and Cost Comparison
Rather than purchasing a new truck, the owner opted for restoration. Key decisions included:
Field Anecdotes and Practical Insight
In Manitoba, a local wrecker known for hoarding rare ADT parts was contacted for planetary gear availability. Though eccentric, such specialists often hold the key to affordable restoration.
In Florida, Alt-Source was praised for reliable shipping and fair pricing on used Volvo parts. Their inventory includes transmissions, axles, and cab components for multiple generations of ADTs.
Recommendations for Restoration Projects
Restoring a Volvo A25C with planetary gear damage is a practical alternative to purchasing new equipment, especially when supported by reliable salvage networks and specialized suppliers. With careful planning and mechanical diligence, these rugged haulers can return to full service, hauling loads and earning revenue for years to come.

Terminology Notes
- Planetary Gear: A gear system used in final drives to distribute torque efficiently; damage to this gear can immobilize the truck.
- ADT (Articulated Dump Truck): A heavy-duty hauler with a pivot joint between cab and dump body, allowing better maneuverability on uneven terrain.
- Final Drive: The last stage in the drivetrain, transferring power from the transmission to the wheels.
- Salvage Yard: A supplier of used or reconditioned parts, often specializing in discontinued or rare equipment.
After acquiring the A25C at auction, the new owner addressed several known issues:
- Repaired air leaks
- Replaced a faulty compressor
- Serviced the braking system
Parts Sourcing and Cost Comparison
Rather than purchasing a new truck, the owner opted for restoration. Key decisions included:
- Used Parts vs OEM: A salvage yard in South Carolina provided a replacement door for $200, compared to Volvo’s OEM price of $2,500.
- Planetary Gear Replacement: Specialized suppliers like Alt-Source and Centranz were recommended for gears and drivetrain components. Centranz can fabricate gears if originals are unavailable.
- Total Cost Estimate: $20,000 for the truck at auction, plus $7,000 in parts and labor—far below the $250,000 cost of a new ADT.

Recommendations for Restoration Projects
- Inspect All Final Drive Components: Gear damage may extend beyond visible teeth.
- Use Reputable Salvage Suppliers: Ensure parts are inspected and compatible with your model.
- Document All Repairs and Sources: Helps with future maintenance and resale value.
- Consider Fabrication for Rare Parts: Companies like Centranz offer custom gear manufacturing.
- Balance Cost vs Downtime: Restoration saves money but may require longer lead times.
