WW PM-34P

Frequently Asked Questions

Q: What is the purpose of the WW PM-34P pivot pin on a Dayton 3KR84?
A: The WW PM-34P is the pivot pin that connects the pump arm assembly to the hydraulic pump body on Dayton 3KR84 manual pallet jacks. It serves as the rotational axis for the pump arm, allowing the operator to apply pumping force to build hydraulic pressure and raise loads.

Q: Is the WW PM-34P compatible with manual pallet jack brands other than Dayton?
A: The WW PM-34P is manufactured for Dayton model 3KR84 equipment only. Pivot pin specifications vary by manufacturer and pump design. Do not substitute this part on Crown, Toyota, Raymond, or other brand pallet jacks. Verify your equipment model and contact us to confirm correct part compatibility before ordering.

Q: What symptoms indicate the WW PM-34P pivot pin is worn or damaged?
A: Signs of pivot pin failure include: excessive play or movement in the pump arm when the jack is not being operated, noise or grinding during pumping, the pump arm does not return to rest position after pumping, or visible cracks or bending in the pin. These conditions reduce pumping efficiency and must be corrected to maintain safe load handling.

Q: What material and finish does the WW PM-34P pivot pin use?
A: The WW PM-34P is a hardened steel pivot pin with a chrome-plated finish to resist corrosion and wear. The hardness provides durability against the shear forces generated during repeated pump cycles. Chrome plating protects against moisture and warehouse chemicals that can cause rust and accelerate failure.

Q: How often should the WW PM-34P pivot pin be inspected or maintained?
A: Inspect the pivot pin quarterly in high-use environments or annually in standard warehouse use. Check for movement between the pin and the pump arm, surface corrosion, or cracks. Lubricate the pin with a light machine oil during maintenance to reduce friction and extend service life. Replace if movement exceeds normal clearance or if visible damage is present.
