FAQ

Q1: How do I confirm this valve guide fits my Komatsu 6D155 engine?
A: To ensure a correct fit, please compare the dimensions of your original valve guide with the OEM size specifications of this part. Common measurements include the outer diameter, inner diameter (valve stem bore), and overall length. If possible, provide your engine serial number or the original part number to our support team for cross-referencing.

Q2: What are the signs that a valve guide needs replacement?
A: Typical symptoms include excessive oil consumption, blue smoke from the exhaust (especially on startup), reduced engine compression, and a ticking noise from the valve train. During a cylinder head rebuild, it is standard practice to replace all valve guides to ensure consistent performance and prevent future failures.

Q3: Is professional installation required for this valve guide?
A: Yes, installing a valve guide requires precision tools and experience. The old guide must be properly pressed out, and the new guide pressed in to the correct depth to avoid damaging the cylinder head. We strongly recommend that installation be performed by a qualified diesel mechanic or machine shop to ensure proper alignment and avoid costly engine damage.
