Camshaft for Caterpillar 3408 Engines

The camshaft is one of the most critical moving parts inside the Caterpillar 3408 engine, controlling the precise timing of the intake and exhaust valves. Our replacement camshaft is designed exclusively for the Caterpillar 3408, including the 3408B and 3408C variations. It is fully compatible with engines carrying serial prefix numbers 99U, 1LG, 8RG, 1TS, and TAM, ensuring a direct fit without modification.

Built to Caterpillar OEM specifications, this camshaft restores original engine performance by maintaining accurate valve lift, duration, and overlap. The result is smoother power delivery, optimal combustion efficiency, and long-term reliability in both industrial and marine applications. Whether you are performing a complete overhaul, repairing a worn camshaft, or rebuilding a high-hour engine, this replacement part provides the strength and dependability expected from the legendary 3408 platform.

Camshaft Bushings for Caterpillar 3408 Engines

The camshaft bushings act as critical support bearings, reducing friction as the camshaft rotates inside the block. Worn bushings can cause excess vibration, misalignment, or even camshaft failure, which makes proper replacement essential during overhauls.

Standard Camshaft Bushing – 1.00" Wide

This standard-width camshaft bushing is specifically engineered for the Caterpillar 3408 engine. At 1.00" wide, it provides stable support for the camshaft under normal operating conditions. Manufactured with precision tolerances, it ensures proper alignment and helps extend the service life of both the camshaft and the surrounding engine components by minimizing metal-to-metal contact.

Wide Camshaft Bushing – 1.30" Wide

For applications where the Caterpillar 3408 is subjected to particularly heavy-duty loads or extended operating hours, the 1.30" wide camshaft bushing offers additional bearing surface. This wider design increases stability, reducing wear on the camshaft journals and block while maintaining smooth rotation. Both standard and wide bushings are designed for easy installation during engine service, making them an essential part of any thorough rebuild.

Camshaft Gear for Caterpillar 3408 Engines

The camshaft gear is responsible for transferring power from the crankshaft to the camshaft, ensuring that valves open and close in perfect synchronization with piston movement. For the Caterpillar 3408, our camshaft gear is a brand-new replacement with 86 teeth, manufactured to precise tolerances to prevent timing errors.

Constructed from high-strength materials, this gear resists the stress and torque generated in large-displacement diesel engines like the 3408. A properly functioning camshaft gear is vital to maintaining efficiency, fuel economy, and reliability across thousands of operating hours. This replacement is ideal for operators seeking to restore their 3408 engine to peak condition and avoid costly downtime caused by gear wear or failure.

Valve Lifters (Tappets) for Caterpillar 3408 Engines

Valve lifters, also known as tappets, are the link between the camshaft lobes and the engine’s valves. In the Caterpillar 3408, these components must endure constant contact and repetitive motion under high loads. Our replacement lifters are engineered for durability and consistent performance.

They ensure that the camshaft’s rotational energy is effectively transferred into precise vertical motion to open and close intake and exhaust valves. High-quality construction reduces wear on both the lifters and the camshaft lobes, prevents sticking, and minimizes noise. By installing new lifters during a rebuild, you ensure smoother operation, reliable timing, and reduced maintenance needs over the life of the engine.
