4D94 Valve Guide 6209-19-1310 for Komatsu Engine Parts Diesel

Product Details

Product Overview

This is a high-precision Valve Guide, specifically identified by the part number 6209-19-1310. Designed for use in the Komatsu 4D94 diesel engine, this component is a critical part of the cylinder head assembly. It ensures the accurate and consistent operation of the intake and exhaust valves, which is essential for maintaining compression, fuel efficiency, and overall engine performance.

Manufactured to OEM size specifications, this valve guide is a direct replacement part. While it is commonly used for Komatsu 4D94 engines, it is prudent to confirm compatibility with your specific engine serial number or cylinder head casting to ensure a perfect fit. This part is ideal for rebuilding cylinder heads in a variety of industrial, agricultural, and construction machinery.

Key Features & Benefits

• OEM Standard Dimensions: Manufactured precisely to OEM specifications (6209-19-1310), ensuring a direct, hassle-free fit without the need for modifications.
• Enhanced Valve Stem Guidance: Provides a precise, low-friction surface for the valve stem, reducing lateral wear and ensuring proper valve seating for maximum compression.
• Durable Material Composition: Constructed from high-grade, wear-resistant materials designed to withstand the extreme heat and friction of the combustion chamber, extending service life.
• Reduced Oil Consumption: A properly fitted valve guide helps maintain the correct valve stem-to-guide clearance, minimizing oil leakage into the combustion chamber and reducing blue smoke emissions.
• Reliable Engine Performance: Restores factory-spec valve operation, leading to smoother idling, better fuel economy, and consistent power output in your Komatsu equipment.
• Rigorous Quality Control: Each valve guide undergoes strict dimensional and material inspection before packaging to guarantee reliability.

FAQ

Q: How do I know if this valve guide (6209-19-1310) fits my engine?
A: This part is specifically designed for the Komatsu 4D94 engine. To confirm fitment, please check the part number stamped on your old valve guide. If it reads 6209-19-1310, it is a direct replacement. If you are unsure, measure the outer diameter and length of your old guide and compare it to the OEM specifications for the 4D94. We recommend consulting your engine’s service manual for exact tolerances.

Q: What is the recommended installation procedure for a valve guide?
A: Installation should be performed by a qualified diesel mechanic. The old guide must be pressed out using a proper valve guide tool. The cylinder head bore should be cleaned of carbon deposits. The new guide should be coated with light engine oil and pressed in from the top of the cylinder head to the correct height (protrusion). Important: After installation, the valve guide bore must be reamed to the correct valve stem clearance using a proper reamer to ensure a perfect fit and prevent valve sticking.

Q: What is the typical lifespan of this valve guide, and what are signs of failure?
A: The lifespan depends on engine hours, maintenance, and operating conditions. Signs of a worn valve guide include excessive blue smoke from the exhaust (especially on startup), increased oil consumption, a ticking noise from the valvetrain, and poor engine compression. If you notice these symptoms during a cylinder head rebuild, replacing the valve guides is highly recommended. Our guides are built to match OEM durability for long service life.
