Frequently Asked Questions
Q: What is the 00591-10921-81 condenser used for?
A: The 00591-10921-81 is a condenser (capacitor) for the ignition system on forklift trucks with internal combustion engines. It prevents arcing across the ignition points and stabilizes the electrical discharge. The condenser must be replaced whenever ignition points are serviced or when electrical arcing occurs.
Q: How do I install the 00591-10921-81 condenser?
A: Turn off the engine and disconnect the battery. Locate the condenser mounted near the distributor or on the breaker plate. Disconnect the wire terminal from the ignition points. Remove the condenser mounting bracket screw. Install the new condenser, reconnect the wire terminal, and secure the bracket. Do not over-tighten the mounting screw.
Q: What are the symptoms of a failing 00591-10921-81 condenser?
A: Symptoms include engine misfiring, hard starting, rough idling, ignition points that burn or pit prematurely, and spark plug fouling. The engine may run poorly or stall under load. If replacing ignition points does not resolve the misfiring, the condenser is likely the cause.
Q: How often should the 00591-10921-81 condenser be replaced?
A: Replace the condenser when ignition points are serviced as part of a maintenance routine, typically every 12 to 18 months or 200 to 300 operating hours. Replace immediately if you experience ignition failure or arcing. Preventive replacement reduces downtime and improves engine reliability.
Q: What is the capacitance rating of the 00591-10921-81?
A: Verify the microfarad (µF) rating in your equipment service manual. Typical forklift condensers range from 0.15 µF to 0.25 µF. Using a condenser with incorrect capacitance will result in poor ignition performance. Cross-reference the exact specification before ordering to ensure correct fitment.
Q: Which forklift brands use the 00591-10921-81 condenser?
A: The 00591-10921-81 is compatible with gasoline and LPG forklift engines from Crown, Toyota, Yale, Hyster, Clark, and Mitsubishi. Confirm your engine model and fuel type in your equipment documentation. Contact our parts team to verify compatibility with your specific forklift model.
