FAQ

Q: Is this a single seat or a kit?
A: This part number (8-94390783-2) typically refers to the necessary components for one valve assembly, which includes the spring seat and its associated washer. Please confirm the exact contents per package with your sales representative for your specific order quantity.

Q: Can this part be used on other Isuzu engine models like the 4HK1 or 6HK1-TCS?
A> While the 6HK1 shares a family lineage with other HK1 engines, valve train components are often model-specific due to differences in bore, stroke, and head design. This part is confirmed for the standard 6HK1. For use in 4HK1, 6HK1-TCS, or other variants, a direct cross-reference from the specific engine’s parts manual is essential before purchase.

Q: What is the critical role of the spring seat in engine maintenance?
A> The valve spring seat provides a perfectly flat, hardened surface for the valve spring to bear against. It distributes the spring’s load evenly across the cylinder head, prevents the spring from digging into the softer head material, and maintains the spring’s correct installed height. Replacing worn seats is crucial during any cylinder head overhaul to restore engine performance and prevent premature valve train failure.
