Distributor cap
Frequently Asked Questions
Q: What engines use SKU 19101-76003-71?
A: This distributor cap fits 4-cylinder engines in Toyota, Clark, and Mitsubishi forklifts. It is commonly found in models with LPG fuel systems and inline 4-cylinder configurations. Verify your equipment nameplate and engine code before purchasing.
Q: What terminal configuration does this cap have?
A: This cap has four side terminals arranged 90 degrees apart plus one center high-tension terminal. The side terminals connect to spark plug leads; the center terminal receives voltage from the ignition coil. Terminal spacing is 35 mm on a circular base.
Q: How often should I inspect this cap for wear?
A: Inspect every 500 operating hours or quarterly, whichever comes first. Look for surface cracks, carbon tracking between terminals, corroded or pitted contacts, and rotor bore wear. Replace immediately if cracks exceed 2 mm in length or electrodes show pitting deeper than 0.5 mm.
Q: What causes premature failure of this cap?
A: High underhood temperatures above 95 degrees Celsius, moisture from wet floor operations, carbon buildup from rich fuel mixtures, and physical impact during handling all accelerate failure. Phenolic material becomes brittle when exposed to extreme heat cycling or UV light.
Q: Are there OEM and aftermarket versions of this part?
A: Yes. Toyota OEM caps have thicker phenolic walls and brass contacts with nickel plating. Aftermarket equivalents cost less but may have thinner material and lower-grade contact plating. OEM parts typically provide longer service life in high-volume operations.
Q: What rotor part number pairs with this cap?
A: This cap uses rotor SKU 19100-76003-71 or equivalent. The rotor must match the cap terminal layout exactly. Using a rotor with incorrect terminal count or spacing prevents proper spark delivery and causes misfires across all cylinders.
