WW PM-36P

Frequently Asked Questions

Q: What is the purpose of the WW PM-36P snap ring on a Dayton 3KR84 pallet jack?
A: The WW PM-36P is a retaining snap ring that secures internal pump assembly components within the Dayton 3KR84 hydraulic pump body. It holds the pump plunger, bearings, or valve seats in their correct axial position during lift and lower cycles, preventing components from shifting or coming loose during operation.

Q: Does the WW PM-36P snap ring fit other manual pallet jack manufacturers?
A: The WW PM-36P is manufactured for Dayton model 3KR84 pump assemblies only. Snap ring specifications including internal diameter, wire thickness, and spring tension are matched to this model. Using incorrect snap rings can result in component shifting, loss of pressure, or sudden pump failure. Confirm your equipment model before ordering.

Q: What symptoms indicate the WW PM-36P snap ring has failed or become loose?
A: Signs of snap ring failure include: loss of hydraulic pressure during lifting, pump makes grinding noise, load does not hold at height or slowly descends with no operator input, or metal debris is visible in the hydraulic fluid. These conditions indicate internal pump components have shifted or become damaged and require immediate attention to prevent further damage.

Q: What material and specifications does the WW PM-36P snap ring have?
A: The WW PM-36P is a stainless steel retaining ring with a spring-loaded design to maintain constant pressure against the bore. It resists corrosion from warehouse moisture and hydraulic fluid additives. Internal diameter is precision-machined to 1.250 inches with a wire diameter of 0.095 inches to ensure secure fit within the Dayton pump body.

Q: Is the WW PM-36P a wear item that requires routine replacement?
A: The WW PM-36P is not a scheduled wear item. Under normal warehouse conditions, snap rings last the life of the pallet jack unless the pump is disassembled for service. Replacement is needed only if the ring becomes loose, fails to maintain proper spring tension, or shows cracks. If you access the pump for bearing or seal service, inspect the snap ring and replace if tension has diminished.
