Frequently Asked Questions
Q: What is the JT JHS1100-43 spring pin and where is it used?
A: The JT JHS1100-43 is a spring pin (also called a roll pin or tubular pin) used in the Toyota JHS1100 pump assembly to retain and align mechanical components. Spring pins hold shafts, levers, or linkage elements in their correct positions under operating load and vibration.
Q: What are the specifications of the JT JHS1100-43 spring pin?
A: This is a metric spring pin with a specific diameter and length engineered for the JHS1100 pump design. The pin is slotted lengthwise to provide spring tension that locks it into a drilled bore. Do not substitute with solid pins or different sizes.
Q: Which Toyota pallet jack models use the JT JHS1100-43 spring pin?
A: This spring pin is used in the JHS1100 hand pump series found on Toyota manual pallet jacks. Confirm your pallet jack uses this specific pump model before ordering. Other pump series may use different pin sizes and materials.
Q: What material is the JT JHS1100-43 spring pin made from?
A: This spring pin is made from hardened and tempered alloy steel with a zinc or nickel plating for corrosion resistance. The slot design creates a spring action that holds tension without needing a lock washer or secondary fastener.
Q: What happens if the JT JHS1100-43 spring pin fails?
A: A broken or missing spring pin will cause linkage components to shift or separate, resulting in loss of pump engagement, inability to develop pressure, or mechanical binding. The pump linkage may disconnect and the jack becomes inoperable.
