How to Remanufacture a 22568 Drop Box for Volvo Articulated Haulers

The 22568 drop box is a critical component in Volvo articulated haulers, responsible for distributing power from the transmission to the axles and enabling effective all-wheel drive functionality. Over time, wear and tear can degrade the performance of this drop box, making remanufacturing an essential process for extending its lifespan and ensuring optimal performance.

Remanufacturing a 22568 drop box involves a comprehensive disassembly, component replacement, reassembly, and testing process to meet or exceed OEM specifications. Below is a step-by-step guide on how these units are properly remanufactured.

Step 1: Initial Inspection & Disassembly

1. Complete Disassembly – The drop box is fully disassembled, and all internal components, including gears, bearings, shafts, seals, and the housing, are removed and organized for inspection.
2. Visual and Dimensional Inspection – Each component is inspected for signs of wear, cracks, warping, and damage. Key tolerances are measured against OEM specifications to determine which parts need replacement.
3. Structural Assessment – The housing is checked for cracks or deformation that may impact reassembly and operation.

Step 2: Cleaning & Surface Preparation

1. Degreasing & Dirt Removal – Components are cleaned using industrial-grade cleaning solutions, ultrasonic cleaning, or media blasting to remove oil, grease, and debris.
2. Surface Restoration – Rust and corrosion are eliminated from metal surfaces. The housing may be resurfaced or machined if necessary to restore flatness and ensure a proper seal during reassembly.

Step 3: Replacement of Worn Components

1. Bearings, Seals, and Gaskets – All worn or damaged bearings, seals, and gaskets are replaced with new, high-quality components to prevent leaks and ensure smooth operation.
2. Gear and Shaft Replacements – If the gears or shafts exhibit excessive wear or damage, they are either replaced with new ones or precision-machined to restore proper function.
3. Upgrading Components – Some remanufacturers opt for improved materials or upgraded parts to enhance durability and performance.

Step 4: Machining & Reconditioning

1. Bearing Bores & Shafts – If necessary, machining is performed to restore proper tolerances in bearing bores, shafts, and mating surfaces.
2. Gear Teeth Refinishing – High-wear components such as gears and clutches may be reconditioned to meet operational standards.
3. Precision Machining – The goal is to restore the drop box to factory tolerances, ensuring smooth functionality and minimal wear over time.

Step 5: Reassembly & Precision Alignment

1. Careful Component Installation – The drop box is reassembled with strict adherence to OEM specifications.
2. Proper Torque & Clearances – Bearings, gears, and shafts are aligned and torqued to precise values to ensure efficient power transmission.
3. Seal Integrity – New seals and gaskets are installed to eliminate any risk of leaks, ensuring longevity.

Step 6: Testing & Quality Control

1. Leak & Pressure Testing – The assembled drop box undergoes pressure testing to detect any leaks in the system.
2. Spin Testing – Some remanufacturers conduct a spin test to verify smooth rotation and ensure proper load distribution.
3. Final Quality Inspection – A thorough quality control check is performed, ensuring that all tolerances and specifications meet factory standards.

Step 7: Painting & Finishing

1. Protective Coating – The drop box housing is repainted or coated to prevent corrosion and extend service life.
2. Labeling & Identification – Serial numbers or identification labels are applied for tracking and warranty purposes.

Step 8: Packaging & Shipping

1. Proper Packaging – The remanufactured drop box is securely packed to prevent damage during transit.
2. Ready for Installation – Once shipped, it is ready for immediate installation into a Volvo articulated hauler, reducing downtime for equipment operators.

Why Choose a Remanufactured 22568 Drop Box?

• Cost Savings – Remanufactured drop boxes are significantly more affordable than brand-new replacements.
• Performance Guarantee – Many suppliers offer warranties, ensuring reliability and long-term performance.
• Reduced Downtime – Remanufactured units are often in stock and ready for shipment, preventing extended equipment downtime.

For those in need of a remanufactured 22568 drop box, suppliers like Industrial Reman offer expertly rebuilt units to meet the demands of heavy-duty Volvo articulated haulers.

By following this structured remanufacturing process, drop boxes can be restored to like-new condition, ensuring continued reliability and optimal performance in demanding applications. Whether purchasing a remanufactured unit or rebuilding an existing one, proper procedures and high-quality components are essential for longevity and efficiency.
