What does the 0.025mm undersize mean for my engine rebuild?

The 0.025mm undersize indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.025mm. This is a common practice during engine rebuilding to ensure proper oil clearance if the original journals are worn or have been ground undersize.

Why is oil clearance important for rod bearings?

Proper oil clearance is critical because it allows a thin film of oil to flow between the bearing and the crankshaft. This oil film prevents direct metal-to-metal contact, reducing friction and wear, and dissipating heat, which is essential for the longevity of your engine.

Are these bearings sold individually or as a set?

This part number (CB1888P25MM(4)) represents a set of connecting rod bearings. Typically, rod bearings are installed in sets, with one bearing per connecting rod journal.

Product Details

These Clevite connecting rod bearings are built with a 0.025mm undersize, meaning they are designed to be used when the crankshaft journals have been machined down by 0.025mm during an engine rebuild. This undersize specification is crucial for achieving the correct oil clearance, which is vital for proper lubrication and the longevity of your Mercedes-Benz OM 904LA or OM 924LA engine, especially those rated up to 170 horsepower. Proper oil clearance allows the engine oil to flow correctly between the bearing and the crankshaft, preventing metal-on-metal contact and reducing wear.

Clevite is known for making well-built engine components, and this rod bearing set is no exception. They are designed to meet the specific demands of these Mercedes-Benz diesel engines, ensuring that your engine runs smoothly and reliably after a rebuild. Installing these bearings correctly, with the appropriate torque specifications and ensuring the crankshaft journals are clean and within the specified tolerance, is key to a successful engine repair.
