Frequently Asked Questions
Q: What is the purpose of the 1-987-429-117 air filter?
A: The 1-987-429-117 is an engine air intake filter that removes dust, debris, and contaminants from the air drawn into the internal combustion engine. This protects engine components from premature wear and maintains proper fuel-to-air combustion ratios on ICE-powered forklifts.
Q: Which forklift models are compatible with the 1-987-429-117?
A: The 1-987-429-117 is designed for forklifts from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Clark, Mitsubishi, CAT, BT, and other OEM manufacturers using this filter specification. Match your equipment model and engine type to the original part number for accurate fitment.
Q: What are the dimensions and material specifications?
A: The 1-987-429-117 contains a pleated paper or foam filter media designed to capture particles 10 microns and larger. Exact dimensions vary by application but typically measure 3 to 6 inches in diameter or length. Consult the specification sheet for precise sizing and filter class rating.
Q: How often should the 1-987-429-117 be replaced?
A: Replace the filter every 200 to 500 operating hours or per your forklift manufacturer recommendations. In dusty warehouse or outdoor environments, replacement intervals may be shorter. Visual inspection showing dirt accumulation or a clogged appearance indicates replacement is needed sooner.
Q: What problems occur if this air filter is not replaced regularly?
A: A clogged 1-987-429-117 restricts air flow, reducing engine power and fuel efficiency, increasing smoke emissions, and causing rough idle or stalling. Prolonged use with a blocked filter damages the engine by allowing unfiltered debris into cylinders, causing accelerated wear on pistons, rings, and valves.
