Frequently Asked Questions

Q: What pallet jack models does the WW PM-5F load wheel fit?
A: The WW PM-5F is an aftermarket replacement load wheel for Dayton manual pallet jacks and Grainger model 3KR84. It is designed as a direct fit for the original axle and bore geometry of these machines. This is a load wheel, not a steer wheel.

Q: What are the exact dimensions of the WW PM-5F load wheel?
A: The WW PM-5F measures 3 inches diameter by 3 3/4 inches width with a 47/15 inch bore specification. These dimensions are critical for axle fitment, so verify your current wheel dimensions match before ordering.

Q: What tread material and hub material does this wheel use?
A: The tread is black ultra-polyurethane and the hub is steel. Ultra-polyurethane provides good grip and wear resistance, while the steel hub offers durability and strength under load. This combination is standard for manual pallet jack load wheels.

Q: Are bearings pre-installed on the WW PM-5F?
A: Yes, the WW PM-5F comes with pre-installed bearings integrated into the assembly. This simplifies fitment and reduces assembly time. The bearings are sealed to keep contaminants out in warehouse environments.

A: The WW PM-5F is also referenced as WWPM-5F, WWPM5F, and PM5F. These are the same part with formatting variations. The SKU WW PM-5F is the current standard designation for inventory and ordering.

Q: When should I replace load wheels like the WW PM-5F?
A: Load wheels wear gradually with use. Replace them when you notice flat spots, chunking of the polyurethane tread, uneven wear, or reduced traction. Under typical warehouse conditions, load wheels last 18 to 36 months. Monitor regularly to prevent rim damage or axle wear.
