5L2952 Cap As-Oil Filler — Cat 120H 120H ES

This is an Oil Filler Cap, a sealed closure for the engine's oil fill opening, preventing contamination and ensuring proper crankcase ventilation. Manufactured to OEM standards, it provides a secure seal and durable construction, unlike worn or damaged caps that can allow dirt ingress or oil leaks. Operators may notice oil leaks around the fill port, or potentially increased crankcase pressure if the cap's seal is compromised.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a faulty oil filler cap is often an oil leak around the fill port or a noticeable increase in engine bay grime accumulation. If the seal deteriorates further, it can lead to increased crankcase pressure, potentially forcing oil past other seals. The consequence of a missing or improperly sealed cap is contamination of the engine oil, leading to accelerated internal wear.

Installation Tip

Ensure the sealing surface on the engine's oil fill neck is clean and free of old gasket material or debris before installing the new cap. Do not overtighten the cap, as this can damage the seal or the threads.

Service Note

When replacing the oil filler cap, check the engine oil level and condition, and inspect the surrounding area for any other oil leaks.
