FAQ

Q1: How do I confirm these valves fit my specific 4TNE98 engine?
A: Verify the part numbers on your existing valves match either 129103-13212 (intake) or 129105-14213 (exhaust). Also check the engine serial number plate to confirm it is a 4TNE98 model. If you have a different valve number, please contact us with your engine details for cross-reference assistance.

Q2: What is the recommended installation procedure for these valves?
A: Installation should follow the Yanmar 4TNE98 service manual. Key steps include: cleaning the valve guide bore, applying molybdenum disulfide to the valve stem, checking valve spring tension, and adjusting valve clearance to specification. Always replace valve stem seals and grind valve seats if necessary. We recommend professional installation by a qualified diesel mechanic.

Q3: How can I extend the service life of these engine valves?
A: Proper maintenance includes: regular valve clearance adjustments at recommended intervals, using clean fuel and oil to prevent carbon buildup, avoiding engine overheating, and inspecting valves during major overhauls. In high-hour applications, consider replacing valves as a set during rebuilds to ensure even wear patterns.
