CAT 416-8319 Valve Lifter Assembly

Product Overview

The CAT 416-8319 Lifter As-Va is a Genuine Caterpillar OEM valve lifter assembly designed for use in Caterpillar engine valve train systems. The valve lifter follows the camshaft lobe profile and transfers camshaft motion through the valve train to open and close the engine’s intake and exhaust valves with precise timing. Manufactured to Caterpillar’s exact engineering specifications, the 416-8319 Valve Lifter Assembly delivers reliable valve train operation, durability, and long service life in demanding heavy-duty applications. The part has been discontinued by Caterpillar, and customers should contact an authorized Cat dealer for replacement options.

As a Genuine Caterpillar OEM replacement part, the valve lifter is engineered to restore factory valve train performance, maintain proper valve timing, and ensure dependable engine operation under severe operating conditions. Caterpillar identifies 20R-1626 Cat® Reman Valve Lifter as the available remanufactured alternative.

Technical Specifications

Note: Caterpillar has not published additional specifications such as material composition, outside diameter, weight, lubrication details, or operating clearances for the CAT 416-8319 Valve Lifter Assembly.

Application Information

The CAT 416-8319 Valve Lifter Assembly is an integral component of the engine valve train. As the camshaft rotates, the valve lifter follows the cam profile and transmits motion through the remaining valve train components to accurately open and close the engine valves. Proper valve lifter operation is essential for maintaining correct valve timing, combustion efficiency, engine power, fuel economy, and emissions performance.

Manufactured to Caterpillar OEM standards, the valve lifter is designed to withstand:

• Continuous camshaft contact
• High engine operating temperatures
• Constant lubrication exposure
• Heavy valve train loads
• Severe industrial, mining, marine, and power generation operating conditions

These characteristics help maintain reliable engine performance and long service life.
