FAQ

Q1: How do I know if my C6.6 engine needs a new thrust washer?
A: Signs of a worn thrust washer include excessive crankshaft end-play, which can often be felt as a knocking sound from the lower engine block, especially when shifting loads. It can also lead to premature main bearing failure. If you are rebuilding your C6.6 engine, replacing the thrust washer is a standard and critical step.

Q2: Is this an exact fit for my 320D excavator?
A: This part is designed for engines using the Caterpillar C6.6 platform, which is commonly found in 320D and 323D excavators. However, minor design variations can occur across different production years and engine serial numbers. We strongly recommend cross-referencing your old part number (370-5646 or 311-2011) to confirm a direct match before purchase.

Q3: Can I install this thrust washer myself?
A: Installation requires disassembling the engine’s lower end, including the oil pan and main bearing caps. This is a precision task that requires specific tools (like a torque wrench) and knowledge of engine assembly procedures. If you are not a qualified diesel mechanic, we recommend having the part installed by a professional to avoid engine damage.
