Product Details
Product Overview
This high-quality Valve Seat is specifically designed for the Caterpillar C15 diesel engine, a workhorse in heavy-duty construction, industrial, agricultural, genset, marine, and material handling applications. The part numbers 167-0643 and 167-0642 are critical identifiers for this component, ensuring precise fitment and reliable sealing within the cylinder head.
Manufactured to OEM size specifications, this valve seat is an essential part for engine overhauls and rebuilds. It is commonly used as a direct replacement for worn or damaged seats, restoring compression and valve train integrity. While this component is designed to match OEM specifications, we always recommend verifying fitment against your specific engine serial number and cylinder head casting for absolute compatibility.
Key Features & Benefits
Precise Fitment: Machined to exact OEM dimensions (167-0643 / 167-0642) for seamless installation into C15 cylinder heads, reducing downtime.
Durable Construction: Built from high-strength, wear-resistant materials to withstand extreme combustion temperatures and pressures typical of C15 diesel engines.
Restored Engine Performance: A new valve seat ensures proper valve sealing, leading to improved compression, fuel efficiency, and reduced emissions.
Extended Service Life: Engineered for longevity in demanding applications like mining, construction, and power generation, minimizing the frequency of future repairs.
OEM Quality Standard: Manufactured to meet or exceed original Caterpillar specifications, providing confidence for professional rebuilders and fleet managers.
Easy Identification: Clear part number marking (167-0643 & 167-0642) simplifies inventory management and ensures the correct part is used every time.
This valve seat is a direct replacement for the following genuine Caterpillar part numbers:
167-0643 (Primary Part Number)
167-0642 (Alternative/Related Part Number)
Note: These numbers are commonly used for both intake and exhaust valve seats in the C15 head. Please confirm your specific application requirements.
Compatibility
This valve seat is commonly used for the following applications:
Engine: Caterpillar C15 (ACERT and pre-ACERT variants)
Equipment: Caterpillar heavy machinery including off-highway trucks, wheel loaders, excavators, and dozers.
Industries: Construction, Mining, Agriculture, Power Generation (Genset), Marine propulsion, and Material Handling.
Always cross-reference your cylinder head part number and engine serial number for precise compatibility. We do not guarantee fitment for all C15 sub-models without verification.

FAQ
Q: How do I confirm if 167-0643 or 167-0642 is the correct seat for my C15 head? A: These numbers are typically for the valve seat itself. You should remove your old seat and look for the stamped number on its outer diameter or underside. Alternatively, check the cylinder head casting number. If your head uses a 2.000″ OD intake seat and a 1.875″ OD exhaust seat (common for C15), this set is likely correct. We recommend measuring the old seat’s outer diameter and height before ordering.
Q: Is there a difference between the intake and exhaust valve seats for the C15? A: Yes, often there is. The intake and exhaust seats on a C15 can have different outside diameters, heights, and material compositions (exhaust seats are typically harder to resist heat). The set of 167-0643 and 167-0642 may include both types. Please specify if you need a specific position (intake or exhaust) when ordering in bulk.
Q: What should I check during installation? A: Before installation, inspect the cylinder head seat pocket for cracks, pitting, or out-of-round wear. The seat must be installed with a proper interference fit (typically 0.003-0.005 inch). Use a valve seat cutter to ensure the new seat is concentric with the valve guide. After installation, a leak test is highly recommended to verify the seal.
