If you are not attentive to your Level I and II components, you risk damage to your critical Level III engine parts.

Creative engineering and thoughtful design go into creating professional Caterpillar® aftermarket engine parts. These engine parts are designed to be replaced in varying tiers to protect the workhorse components from damage or failure. With regular maintenance and care, Caterpillar® heavy machines (such as bulldozers, tractors with blades and front-end loaders) can perform at high levels for many years.

How Caterpillar® Engine Parts are Categorized

All professional Caterpillar® engine parts are categorized as Level I, Level II and Level III. Level I items are considered disposable and must be checked and replaced regularly. They are not reusable and include parts such as pistons rings, main rod bearings, turbo bearings, valve guides, gaskets, seals and turbo seals.

Level II engine components are slower to wear down and are deemed as reusable. Level II equipment includes valves, camshafts and liners. Finally, Level III Caterpillar® engine parts are the rocks of any machine's mechanical system--camshafts, blocks and cylinder heads. These are considered reusable, but they shouldn't normally have to be replaced.

The different level distinctions describe the importance of each group of parts. What this means is that if you regularly replace Level I and Level II parts, your Level III parts will not suffer from wear and tear that would compromise their integrity. If you are not attentive to your Level I and II components, you risk damage to your critical Level III engine parts.
