Frequently Asked Questions
Q: What is a point set and why is it necessary in ignition systems?
A: SKU 446132 is a point set (contact points) that controls the timing of ignition current by opening and closing an electrical circuit at precise engine intervals. The points work with the distributor to fire spark plugs in the correct sequence and timing for combustion.
Q: What equipment brands use this point set?
A: This point set is compatible with Crown, Toyota, Raymond, Yale, and Hyster forklift engines that use mechanical point-type ignition systems. Confirm your engine model year and distributor type before ordering, as point configurations vary by displacement and firing sequence.
Q: What material are the contact points made from?
A: Contact points are precision-engineered metal surfaces (typically tungsten or alloy) that open and close thousands of times per minute. The material is selected to resist electrical arcing, oxidation, and mechanical wear from repetitive cycling.
Q: How long do point sets last before replacement?
A: Points typically require replacement every 1,500 to 3,000 operating hours under normal conditions. Frequency increases with exposure to moisture, high temperatures, and poor electrical grounding. Heavy-duty forklift applications may require more frequent replacement.
Q: What happens when points wear out or fail?
A: Worn or failed points cause erratic spark timing, rough idle, engine hesitation, poor fuel economy, hard starting, and stalling. Point wear increases the electrical gap, reducing current flow and spark intensity until the engine will no longer fire consistently.
Q: Is point dwell and gap critical for proper operation?
A: Yes. Point gap and dwell angle (the electrical duration the points remain closed) must be precise for correct ignition timing. Incorrect gap or dwell results in timing drift, weak spark, and combustion problems. Verification and adjustment are essential after point replacement.
