FAQ

Q1: How do I know if this part is an intake or exhaust valve for my Yanmar 4TNE88 engine?
A: The OEM part numbers 129150-13350 and 129150-13351 correspond to specific valve types. It is critical to identify the exact valve you are replacing. We recommend checking your engine’s service manual or inspecting the original valve/part number removed from the engine. You can also provide us with your engine’s full model and serial number for verification before purchase.

Q2: Is this a genuine OEM Yanmar part or an aftermarket replacement?
A: This is a high-quality aftermarket replacement part manufactured to OEM specifications. It is designed to provide identical fit, form, and function to the original Yanmar valve at a competitive price point, making it an ideal choice for cost-effective maintenance and overhauls without compromising on performance.

Q3: What is the recommended maintenance practice when replacing engine valves?
A: Valve replacement is a precision task. We strongly recommend replacing valves in sets (e.g., all intake or all exhaust valves for a cylinder bank) to maintain balanced engine performance. Always inspect and likely replace associated components such as valve seals, springs, and guides during service. The cylinder head mating surface and valve seats should be professionally machined or lapped to ensure a perfect seal. Consulting a qualified mechanic or the engine service manual is essential.
