FAQ

Q1: How do I confirm this 6D155 valve fits my Komatsu engine?
A: Verify your engine model number matches “6D155” on the engine data plate. Measure your existing valve’s stem diameter, overall length, and head diameter, then compare with OEM specifications for the 6D155 engine. If in doubt, contact our support team with your engine serial number for cross-reference assistance.

Q2: What is the recommended installation procedure for this engine valve?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) thoroughly clean the valve guide and seat area, 2) apply assembly lubricant to the valve stem, 3) use a valve spring compressor to install the valve and retainers, and 4) check valve clearance according to the Komatsu service manual specifications. Always replace valve stem seals during installation for optimal performance.

Q3: How should I store and maintain spare 6D155 valves?
A: Store valves in a dry, clean environment at room temperature (15-25°C). Keep them in the original packaging to prevent corrosion or physical damage. Avoid exposure to moisture, chemicals, or extreme temperatures. For long-term storage, apply a light coat of rust-preventive oil to the valve stem and face. Inspect visually before installation to ensure no damage occurred during storage.
