Cummins 6CT Engine Parts – Camshaft Section

The camshaft system in the Cummins 6CT 8.3 engine plays a critical role in controlling valve timing and ensuring efficient air and fuel flow through the combustion chambers. A properly functioning camshaft, along with its supporting bushings, push rods, valve lifters, and gaskets, keeps the engine running smoothly, reduces wear, and maximizes reliability. This section of our catalog highlights the essential camshaft-related components designed specifically for the Cummins 6CT.

Camshaft for Cummins 6CT Engines

The camshaft is the central component of the valve train, directly responsible for the opening and closing of the intake and exhaust valves in the 6CT engine. Over time, camshaft lobes can wear, reducing performance and efficiency.

Features and Benefits:

• Built for the Cummins 6CT 8.3 engine

• Hardened surfaces for reduced wear and extended service life

• Precision-ground lobes for accurate valve timing

• Helps restore lost performance in worn engines

Replacing a worn camshaft during overhaul ensures the 6CT continues to deliver dependable performance under heavy-duty operation.

Camshaft Bushing Set for Cummins 6CT

Camshaft bushings support the camshaft and allow smooth, low-friction rotation inside the block. Worn bushings can cause misalignment, reduced oil pressure, and valve timing problems.

Key Details:

• Complete bushing set designed for the Cummins 6CT 8.3

• Precision-machined for correct oil clearance

• Ensures proper lubrication and alignment of the camshaft

• Helps prevent premature wear of the camshaft and block

This set should always be replaced during a rebuild or camshaft service to guarantee long-term reliability.

Push Rods for Cummins 6CT Engines

Push rods transfer motion from the camshaft lobes and lifters to the rocker arms and valves. Damage or bending can lead to valve timing errors, noise, and reduced power.

Benefits of Replacement:

• Manufactured for the Cummins 6CT 8.3

• High-strength steel construction for durability

• Precision-straightened to maintain proper valve operation

• Restores accurate valve train performance

Replacing push rods ensures the camshaft’s motion is transferred efficiently through the valve train.

Valve Lifters (Tappets) for Cummins 6CT

Valve lifters, or tappets, ride directly on the camshaft lobes, transmitting motion to the push rods. If lifters wear unevenly, they can cause excessive noise and damage to the camshaft.

Product Highlights:

• Designed specifically for the Cummins 6CT engine

• Hardened contact surfaces for long service life

• Smooth operation to reduce wear on camshaft lobes

• Essential to replace alongside the camshaft to ensure uniform wear

New lifters help protect a replacement camshaft and extend engine longevity.

Gear Housing Gasket for Cummins 6CT

The gear housing gasket seals the camshaft gear housing to the engine block, preventing oil leaks and maintaining correct lubrication.

Advantages:

• Engineered for the Cummins 6CT 8.3

• Heat and oil resistant material for long-term sealing

• Prevents contamination and pressure loss

• Recommended for replacement whenever the camshaft or front gear housing is serviced

Maintaining a proper seal ensures consistent oil flow to the camshaft and timing gears.
