FAQ

Q: Will these valves fit my Yanmar 4TNE84 engine directly?
A: Yes, these valves are manufactured to OEM specifications for the 4TNE84 engine. However, we recommend comparing the provided part numbers (129150-13350 and 129150-13351) with your existing valves to confirm compatibility, as minor revisions may exist across different engine serial numbers.

Q: Can I install these valves without specialized tools?
A: Valve replacement requires mechanical expertise and proper tools, including a valve spring compressor and torque wrench. We recommend installation by a qualified diesel mechanic. Ensure the cylinder head is clean and valve guides are within specification before installation.

Q: What is the typical service interval for replacing these valves?
A: Valve inspection is generally recommended during major engine overhauls or at intervals specified in your Yanmar service manual (typically 2,000-4,000 hours depending on operating conditions). Replace valves if you notice excessive wear, pitting, or carbon buildup that affects sealing.
