Caterpillar 3406C Camshaft & Related Components Catalog

The camshaft is at the heart of every Caterpillar 3406C diesel engine, precisely controlling the timing of intake and exhaust valves to optimize combustion, power output, and efficiency. Alongside the camshaft itself, a range of supporting components—including gears, bushings, keys, and valve lifters—ensure the camshaft operates smoothly and reliably.

At Diesel Pro Power, we offer a complete catalog of Caterpillar 3406C camshaft and related components, each manufactured to OEM-quality standards for durability, precision, and perfect fit. Whether you are rebuilding your 3406C engine or replacing worn components to extend its service life, our catalog makes it simple to find the right part.

Camshaft for Caterpillar 3406C Engines

The camshaft is a critical rotating component that manages the valve train of the 3406C. Designed to withstand high stress, it delivers accurate valve timing under heavy-duty conditions. Our new camshaft replacements for the Caterpillar 3406C are built to factory specifications, ensuring reliable operation and long service life in marine, industrial, and trucking applications.

Key Benefits:

• Precision-ground lobes for consistent valve timing.

• Manufactured from high-strength alloys to resist wear.

• Compatible with Caterpillar 3406B and 3406C engines.

• Ideal for complete overhauls or targeted replacements.

Camshaft Gear for Caterpillar 3406C Engines

The camshaft gear ensures synchronized operation between the crankshaft and camshaft, maintaining precise timing of the valve train. A properly fitted gear prevents power loss, misfires, and premature wear.

Highlights:

• Machined for perfect tooth engagement.

• Built from durable, heat-treated steel.

• Designed to handle the high torque of the 3406C.

• Maintains factory-correct gear timing.

Camshaft Woodruff Key

The camshaft woodruff key secures the gear to the camshaft, preventing slippage during operation. Though small, this component is vital to maintaining accurate timing.

Why It Matters:

• Ensures proper gear-to-shaft alignment.

• Prevents timing issues caused by gear slippage.

• Compatible with both Caterpillar 3406 and 3412 engines.

Camshaft Bushings for Caterpillar 3406C Engines

Bushings provide stable support and reduce friction where the camshaft rotates within the engine block. Replacing worn bushings is essential during any camshaft installation to prevent premature wear and noise.

Available Options:

• Standard Width Bushings: Designed for standard applications and everyday use.

• Wide Bushings: Provide additional support and load distribution under extreme conditions.

Benefits of New Bushings:

• Reduce vibration and wear on the camshaft.

• Extend engine life by maintaining proper lubrication.

• Precision-machined for correct oil clearance.

Idler Gear Bushing for Caterpillar 3406C Engines

The idler gear bushing supports the idler gear, which helps transmit power between the crankshaft and camshaft gears. A properly functioning bushing ensures smooth gear rotation and prevents excessive wear.

Key Features:

• Built to resist high-load stress.

• Maintains gear alignment and prevents chatter.

• Specifically designed for Caterpillar 3406B and 3406C models.

Valve Lifters (Tappets) for Caterpillar 3406C Engines

Valve lifters transfer motion from the camshaft lobes to the pushrods and ultimately to the valves. Worn lifters can lead to poor valve timing, reduced efficiency, and increased noise.

Features:

• Hardened surfaces for long service life.

• Precision design to reduce friction and wear.

• Compatible with Caterpillar 3406, 3408, and 3412 engines.
