Frequently Asked Questions
Q: What is the primary function of the KO 11073-33 roll pin in lift truck assemblies?
A: The KO 11073-33 is a spring steel roll pin that retains hydraulic cylinder end caps, mast clevis pins, and pump shaft components in Komatsu electric lift trucks. It provides reliable press-fit retention under hydraulic pressure and vibration.
Q: How do I identify whether I need KO 11073-33 versus similar roll pin models?
A: Measure the bore hole diameter and depth of the assembly pocket where the pin seats. Komatsu OEM part numbers encode these dimensions. Consult your equipment service manual or cross-reference your assembly number against the Komatsu parts catalog to confirm KO 11073-33 is correct for your application.
Q: What material composition makes the KO 11073-33 suitable for hydraulic applications?
A: The KO 11073-33 is manufactured from spring steel with high yield strength and elastic memory, allowing it to maintain tension under constant hydraulic pressure. This material resists permanent deformation and provides consistent retention throughout the equipment service life.
Q: Does the KO 11073-33 require lubrication or regular maintenance?
A: The KO 11073-33 does not require routine lubrication. Inspect visually during regular maintenance for corrosion, cracks, or loss of retention. Apply standard hydraulic oil or lithium grease during assembly if recommended by your equipment manual. Replace the pin if you observe surface rust, pitting, or fatigue cracks.
