FAQ

Q: How do I confirm this pulley fits my Yanmar 4TNV98 engine?

A: Verify the number of grooves on your current pulley (it must be double groove). Measure the outer diameter and center bore. For absolute fitment confirmation, compare your original part number (e.g., 119663-22010) with our cross-reference list. If your engine is a 4TNV98T (turbo), the pulley is commonly the same.

Q: What maintenance is required for the crankshaft pulley?

A: During installation, ensure the pulley is torqued to the manufacturer’s specification (typically 180-220 Nm for 4TNV98). Inspect the pulley for wear or cracks during every belt replacement cycle (recommended every 500-1000 hours). If you notice belt squeal or vibration, check the pulley for runout or damage.

Q: Can this pulley be used for marine applications?

A: Yes, the coated cast iron construction provides good corrosion resistance for marine environments. However, for saltwater applications, we recommend additional inspection of the pulley surface during routine engine maintenance. Ensure the engine’s front seal is in good condition to prevent oil contamination of the pulley hub.
