Parts for Caterpillar 3406C – Oil System Section

A dependable oil system is the lifeblood of your Caterpillar 3406C engine. Proper lubrication ensures reduced friction, cooler operating temperatures, and long-term reliability in demanding environments. Diesel Pro Power offers a full range of oil system components for the Caterpillar 3406C, including oil coolers, gaskets, seals, and service tools—all designed for OEM-level performance and global shipping support.

Oil Cooler Core for Caterpillar 3406C Engines

The oil cooler core is a critical part of the 3406C’s lubrication system, responsible for keeping the engine oil at safe operating temperatures. Without proper cooling, oil breaks down faster, leading to reduced protection for pistons, bearings, and other moving parts.

• Durable Design – Built for heavy-duty use, the oil cooler core can withstand constant exposure to high-pressure, high-temperature oil circulation.

• OEM-Level Performance – Manufactured to Caterpillar specifications to ensure precise fit and function.

• Extended Engine Life – By maintaining proper oil temperatures, the cooler core helps prevent overheating, sludge buildup, and premature wear.

Replacing a worn oil cooler core restores efficiency and protects your 3406C under the most demanding conditions.

Oil Pan Gasket for Caterpillar 3406C

The oil pan gasket forms the seal between the oil pan and the engine block, preventing leaks that can lead to oil starvation and engine damage. A reliable gasket is essential for keeping oil where it belongs.

• High-Quality Seal – Designed to resist high heat and constant vibration common in Caterpillar 3406C applications.

• Leak Prevention – Prevents oil seepage, protecting the crankshaft and bearings.

• Easy Installation – Manufactured for an exact fit, minimizing downtime during service.

Regular inspection and replacement of the oil pan gasket ensures consistent lubrication and reduces the risk of costly engine repairs.

Seal O-Ring for Caterpillar 3406C Oil Cooler

Small but essential, the oil cooler O-ring ensures a leak-free seal in the oil cooling system. When O-rings fail, oil pressure drops and leakage can occur, impacting both cooling efficiency and lubrication.

• Precision Fit – Specifically engineered for Caterpillar 3406C, 3408, and 3412 engines.

• Resistant to Wear – Built to withstand constant exposure to oil and heat.

• Critical for Oil System Integrity – A properly sealing O-ring ensures that oil is cooled and circulated correctly.

Replacing the O-ring whenever servicing the oil cooler helps maintain peak reliability.

Oil Filter Removal Wrench

Servicing your Caterpillar 3406C requires the right tools, and an oil filter removal wrench makes routine maintenance easier and faster. Designed to fit a wide range of Caterpillar, Cummins, and Detroit Diesel oil filters, this tool is indispensable for mechanics and operators alike.

• Universal Fit – Works with filters sized 4-21/32" to 5-5/32".

• Durable Construction – Built for repeated use in professional shop or field environments.

• Simplifies Maintenance – Saves time and effort, ensuring filters can be removed without damage.

Keeping the proper tools on hand reduces downtime and ensures oil filter replacements are done quickly and correctly.
