FAQ

Q: Is the Hino 11122-1141 valve the same for intake and exhaust on the W04C engine?
A: Yes, this part number is a standard valve used for both intake and exhaust positions on the W04C and W04C-T engines. However, if your engine requires a sodium-filled exhaust valve for extreme high-load applications, please verify with your engine serial number. We can supply the correct variant if needed.

Q: How do I ensure proper installation without damaging the valve stem?
A: Always use a valve spring compressor tool to avoid side-loading the stem. Lubricate the stem with clean engine oil before inserting into the valve guide. Ensure the valve seat is clean and properly ground to the correct angle (typically 45 degrees for the W04C). Torque the rocker arm adjuster to the manufacturer’s specification after installing the valve.

Q: What is the recommended maintenance interval for replacing these valves?
A: In normal fleet service, we recommend inspecting the valve clearance and condition every 500 operating hours or during major engine overhauls (typically every 10,000–15,000 km for on-highway use). Replace if you observe pitting, stem wear, or a burnt margin. Our valves are designed to last the full engine rebuild cycle when properly maintained.
