Frequently Asked Questions
Q: What is the CL 99639 solenoid used for?
A: The CL 99639 is a solenoid coil assembly for Clark electric lift trucks. Solenoids control electromagnetic switching of directional flow, brake release, or motor enable functions. The specific application depends on the truck model and which circuit the solenoid controls.
Q: What voltage does the CL 99639 solenoid require?
A: The CL 99639 is rated for a specific voltage that matches your Clark truck electrical system, typically 24V, 48V, or 80V DC. Applying incorrect voltage will damage the solenoid coil and prevent proper operation. Verify voltage from your truck documentation before ordering.
Q: How do you diagnose a failing CL 99639 solenoid?
A: A failing solenoid produces symptoms such as loss of directional control, brake not releasing, or inability to operate lift functions despite electrical power being present. The truck may emit a clicking sound when attempting to activate the solenoid.
Q: What is the typical lifespan of a CL 99639 solenoid?
A: In normal material handling service, solenoids typically function for 3,000 to 5,000 operating hours before coil degradation or contact wear necessitates replacement. Operating conditions, ambient temperature, and switching frequency affect actual lifespan.
Q: Which Clark lift truck models use the CL 99639?
A: The CL 99639 solenoid fits multiple Clark electric truck models and generations. Verify your truck model, serial number range, and control system type against the product specification to confirm compatibility.
Q: Are there cross-reference solenoids from other suppliers?
A: Equivalent solenoids must match the CL 99639 in voltage, amperage, coil resistance, and mounting configuration. Always cross-reference against Clark documentation to ensure the replacement solenoid controls the same circuit and performs identically.
