WW PM-33P

Frequently Asked Questions

Q: What does the WW PM-33P release lever do on a Dayton 3KR84 pallet jack?
A: The WW PM-33P is the manual release lever that controls the hydraulic valve on Dayton 3KR84 manual pallet jacks. It allows the operator to lower the load by opening the pressure relief in the hydraulic system. When the lever moves through its full travel, it opens the valve to let pressurized oil return to the reservoir.

Q: Does the WW PM-33P fit pallet jacks other than Dayton 3KR84 models?
A: The WW PM-33P is specifically designed for Dayton model 3KR84 manual pallet jacks. Before ordering, verify your equipment model matches. Using incorrect release levers can result in improper load control or safety hazards. If you need parts for a different Dayton model or brand, contact us for the correct part number.

Q: What are common signs the WW PM-33P release lever needs replacement?
A: Replace the release lever if you observe: the lever sticks or does not return to neutral position, load does not lower smoothly or descends too quickly, the lever is cracked or has lost its grip surface, or the valve does not fully open even when the lever is fully moved. A worn or damaged lever compromises load control.

Q: What material is the WW PM-33P release lever made from?
A: The WW PM-33P is manufactured from ductile cast iron for the lever arm with a steel shaft connection. This material provides the rigidity needed to withstand repeated operator input and the durability required in material handling environments. The design is standard for manual pallet jack release mechanisms.

Q: How long does the WW PM-33P typically last before needing replacement?
A: Under normal warehouse use, the release lever typically lasts 3 to 5 years. Lifespan depends on load cycle frequency, storage conditions, and proper maintenance. Jacks used in humid or outdoor environments may require replacement sooner. Inspect the lever annually for wear or cracks to prevent sudden failure during load lowering.
