Manufactured for the powertrain systems of Komatsu heavy equipment, the part coded 418-18-34110 is the genuine filter cover assembly designed to securely position the filter element within the transmission system. This component plays a critical role in ensuring that transmission oil circulation occurs without leakage under pressure, helping to maintain the overall performance of the system.
It provides seamless installation across various compatible loader models such as WA200-5, WA250-6, WA320-6, and WA320-7. The reference 418-18-34110, or 4181834110 without spaces, is the most reliable guide to verify exact compatibility with the housing on the transmission block. During assembly, the cleanliness of the connection surfaces and the condition of sealing elements such as O-rings must be thoroughly checked.
Before replacement procedures, performing a physical comparison between the thread structures and hydraulic inlet-outlet fittings on the old cover and the 418-18-34110 part is important for accurate part selection.
