Frequently Asked Questions
Q: What is the 903167 contact and what equipment does it fit?
A: The 903167 is an electrical contact component used in electric lift truck and material handling equipment control systems. This part is compatible with multiple electric pallet jack and walkie stacker models from Crown, Raymond, Toyota, Jungheinrich, and similar OEM manufacturers.
Q: What is the function of this electrical contact?
A: This contact completes or breaks electrical circuits in the trucks control or power systems. It is a wear item that conducts electricity under load and may require replacement due to arcing, oxidation, or mechanical wear.
Q: How do I know if the 903167 contact needs replacement?
A: Replace this contact if you notice intermittent loss of power, slow or erratic lift speed, audible clicking or arcing from the control panel, or if continuity testing shows resistance above specification. Burned or corroded contact surfaces are also indicators of failure.
Q: What are the material specifications for this contact?
A: Electric lift truck contacts like the 903167 are typically constructed from silver-plated or nickel-plated copper alloy to resist oxidation and arcing. The exact plating and base material vary by equipment manufacturer and circuit requirements.
Q: What is the typical replacement interval for this contact?
A: The service life of the 903167 depends on switching frequency and electrical load. In high-cycle applications, contacts may need replacement every 1 to 2 years. In lighter-duty use, lifespan can extend to 3 to 5 years or longer.
