Frequently Asked Questions
Q: Which fork lift models does air filter SKU 37Z-02-AF138 fit?
A: SKU 37Z-02-AF138 is compatible with internal combustion engine fork lifts from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Clark, and similar OEM brands. Verify your equipment model year, engine displacement, and engine series to confirm exact fitment before ordering. Incorrect filter size can cause air bypass and engine damage.
Q: What material is used in air filter SKU 37Z-02-AF138?
A: This air filter features a pleated cellulose or synthetic media construction designed to trap particles from 5 to 10 microns depending on media type and pleat density. The media provides high dirt holding capacity while maintaining low airflow restriction. Filter housing seals prevent unfiltered air bypass around the media.
Q: How often should air filter SKU 37Z-02-AF138 be replaced?
A: Replacement interval depends on ambient conditions and engine load. Typical fork lift air filters require replacement every 150 to 500 operating hours in dusty warehouse environments, or every 3 to 6 months in moderate use. Cold storage and outdoor operations may require more frequent changes due to increased moisture and debris exposure.
Q: What are the consequences of using a clogged or damaged air filter?
A: A clogged filter increases airflow resistance, reducing engine power output and fuel efficiency. Excessive restriction can cause engine stalling or hard starting. A damaged or improperly sealed filter allows unfiltered dust and debris to enter the engine, causing accelerated wear to cylinders, pistons, and valves. Replace immediately if filter shows tears, hole, or separation from housing.
Q: How do I identify when SKU 37Z-02-AF138 needs replacement?
A: Visual inspection is the most reliable method: remove the filter and hold it to light. If you cannot see through the media or media appears darkly caked with dust, replacement is needed. Additional indicators include reduced engine power at full throttle, difficulty starting, increased fuel consumption, or visible dust residue inside the air box.
