FAQ

Q: How do I confirm this bearing fits my excavator engine?
A: First, locate the engine model plate on your machine. It should clearly state if it is a J05E or J08E engine. Then, remove the old bearing and check the part number stamped on it. If it matches S1170-12140, this is the correct part.

Q: What is the recommended installation procedure for a main bearing?
A: Installation should be performed by a qualified diesel mechanic. The bearing shell and crankshaft journal must be perfectly clean and oiled. Use a torque wrench to tighten the bearing cap bolts to the exact specifications found in your engine’s service manual. Incorrect torque can cause bearing failure.

Q: How can I extend the life of my new main bearings?
A: Regular engine maintenance is key. Always use the correct grade of engine oil and change it at the recommended intervals. Ensure the oil filter is changed simultaneously. Avoid operating the engine under extreme loads for prolonged periods without proper warm-up. Monitoring oil pressure is also crucial for early detection of bearing wear.
