Distributor cap
Frequently Asked Questions
Q: What engine types use this distributor cap?
A: SKU 446122 is a distributor cap for combustion engines found in internal combustion forklift trucks and material handling equipment. Compatibility includes Crown, Toyota, Raymond, and Hyster models with traditional ignition systems. Verify your engine block size and cap terminal configuration before ordering.
Q: What material is the distributor cap made from?
A: This distributor cap is molded from phenolic resin or high-grade plastic designed to withstand high voltage and thermal stress from ignition arcs. The material resists moisture, oil, and temperature cycling to maintain electrical conductivity and prevent cross-fire between terminals.
Q: How often does a distributor cap need replacement?
A: Distributor caps typically require replacement every 3,000 to 5,000 operating hours under normal conditions. Failure accelerates with moisture exposure, carbon tracking on terminal surfaces, and wear from prolonged electrical arcing.
Q: What is carbon tracking and why is it a problem?
A: Carbon tracking is a conductive path that forms between distributor cap terminals due to moisture and arcing. This causes electrical current to bypass the rotor and fire plugs out of sequence, resulting in loss of power, poor fuel economy, and difficulty starting the engine.
Q: Can I use a universal distributor cap or must I match this exact SKU?
A: SKU 446122 is engineered for specific engine configurations. Terminal count, terminal diameter, and rotor seat configuration must match exactly. Using a universal or incompatible cap will cause ignition misfires and potential engine damage. Verify your engine serial number for the correct replacement.
Q: What problems occur when a distributor cap fails?
A: A failing distributor cap causes rough idle, engine hesitation under load, hard starting, stalling, loss of fuel economy, and visible carbon or tracking marks on terminal surfaces. Complete cap failure results in no spark and complete engine shutdown.
