FAQ

Q: How do I confirm this MP1104K bearing set fits my Hino J08C engine?
A: First, verify your engine’s model number, which is typically stamped on the engine data plate or block. This set is specifically designed for the J08C and J08E platforms. You should also visually compare the old bearing with the new one to ensure the width, diameter, and oil groove patterns match. If you have a specific engine serial number, we recommend contacting our support team for final confirmation.

Q: What are the critical steps when installing new main bearings?
A: Proper installation is vital. Ensure the bearing bores in the block and main caps are perfectly clean and dry. Do not apply oil to the back of the bearing shell. Apply clean engine oil only to the bearing surface. Torque the main cap bolts to the manufacturer’s specifications in the correct sequence and stages. After installation, always check the crankshaft end-float and rotate the crankshaft by hand to ensure it turns freely without binding.

Q: What is the recommended maintenance after installing these new bearings?
A: After an engine rebuild with new bearings, it is critical to perform an initial break-in period. Do not operate the engine under heavy load for the first 50-100 hours. Change the engine oil and oil filter immediately after the break-in period to remove any wear particles. Thereafter, adhere to the Hino engine’s standard oil change intervals using a high-quality diesel engine oil with the correct viscosity grade.
