Restoring a White Lift Forklift and Solving Rear-End Clearance Issues
#1
White Lift Forklifts and Their Legacy
White Lift forklifts were produced during the mid-to-late 20th century by White Motor Company, a Cleveland-based manufacturer known for its trucks, agricultural equipment, and industrial machinery. Though the company ceased operations in the 1980s, many of its forklifts remain in service today, especially in small yards, farms, and independent shops. These machines were built with simplicity and durability in mind, often featuring gasoline engines, mechanical linkages, and robust steel frames. Their longevity is a testament to the overbuilt engineering of the era.
Engine and Cooling System Refurbishment
One owner recently undertook a partial restoration of a White Lift unit powered by a gasoline engine with a carburetor setup. After flushing the engine block, a significant amount of rust was removed, indicating years of sediment buildup. This process is essential for maintaining cooling efficiency, especially in older machines where corrosion can restrict coolant flow and lead to overheating.
Recommendations for similar restorations:
  • Use a chemical flush agent followed by distilled water to remove rust and scale.
  • Inspect the radiator core for blockages and leaks.
  • Replace thermostat and hoses to ensure consistent temperature regulation.
  • Install a coolant filter if the system allows, to trap future debris.
Counterweight Clearance and Driveway Challenges
A recurring issue with older forklifts is the low-hanging counterweight, which can drag or scrape on uneven surfaces. In this case, the rear counterweight was dangerously close to the ground, causing problems on a rough driveway. While some have considered cutting the counterweight using torches or saws, this approach is risky and may compromise the machine’s balance and lifting capacity.
Alternative solutions include:
  • Raising the rear end using hydraulic leveling cylinders
  • Installing taller rear tires if compatible with the drivetrain
  • Regrading the driveway to reduce high spots and dips
Hydraulic Rear Cylinders and Their Function
The rear of the White Lift features hydraulic cylinders known as hydralizers, which act as dynamic spindles. These are connected by a cross tube and serve a dual purpose:
  • Power steering assistance
  • Frame leveling over uneven terrain
When one rear tire encounters an obstacle, the hydralizer system transfers oil across the cross tube, allowing the opposite side to compensate. This mimics the behavior of a steer axle, maintaining stability without rigid suspension.
Maintenance tips for hydralizers:
  • Check the cross tube for leaks
  • Inspect ram movement by jacking up the rear wheels
  • Replace lost fluid with heavy grease using a grease fitting installed in the top plug
  • Avoid overfilling to preserve the cushioning effect
Originally, these cylinders were filled with 90W gear oil, but grease is now preferred due to its sealing properties and ease of maintenance.
Terminology Clarification
  • Hydralizer: A hydraulic cylinder system that balances rear axle movement.
  • Cross Tube: A fluid channel connecting both hydralizers for pressure equalization.
  • Counterweight: A heavy steel mass mounted at the rear to offset front lifting loads.
  • Grease Fitting: A nozzle used to inject lubricant into sealed components.
Field Anecdotes and Practical Advice
A forklift operator in upstate New York reported that after pumping both hydralizers with heavy grease, the rear end lifted by approximately 3 inches, solving the driveway clearance issue. He noted that the machine was only used monthly, so the loss of suspension cushion was acceptable. Another technician in Wisconsin emphasized not raising the rear excessively, as it could accelerate tire wear and reduce steering responsiveness.
Conclusion
Restoring and modifying a vintage White Lift forklift requires a blend of mechanical intuition and practical adaptation. While cutting counterweights may seem tempting, hydraulic solutions like greasing the hydralizers offer safer and reversible alternatives. With proper maintenance and thoughtful upgrades, these classic machines can continue serving reliably—even decades after their original production.
