FAQ

Q: How do I confirm this seal fits my Komatsu 6D170 engine?
A: First, locate the engine model plate on your machine (usually on the valve cover or side of the block). Ensure it reads “6D170”. Then, remove the old seal and check for the OEM part number (6162-29-4500 or 6126-21-3170) stamped on its metal casing. Our seal is a direct cross-reference for these numbers.

Q: What is the installation procedure for this crankshaft seal?
A: Installation requires removing the old seal using a puller tool. Clean the housing bore thoroughly to remove any debris or old sealant. Apply a thin layer of clean engine oil to the seal lip. Using a seal driver tool (or a socket of the correct diameter), gently tap the new seal into the housing until it is flush. Never hammer directly on the seal body, as this can damage the lip and cause premature failure.

Q: What causes a crankshaft oil seal to fail prematurely?
A: The most common causes of failure are: (1) Incorrect installation that damages the sealing lip. (2) Worn crankshaft journals or a damaged surface where the seal rides. (3) Excessive crankcase pressure due to a blocked PCV valve or blow-by. (4) Using a low-quality seal that is not resistant to the specific engine oil additives. Our seal is designed to withstand these conditions, but it is critical to inspect the crankshaft surface during replacement.
