What does the '+0.020 Os Od (Size +0.75mm)' mean for these bearings?

This indicates the bearings are oversized by 0.020 inches, or 0.75mm. This is used when the crankshaft journals have been machined down to this size to account for wear, ensuring proper clearance and oil film.

What is the 'Obstructive' design mentioned?

King's Obstructive bearing design is intended to reduce oil flow compared to standard bearings. This helps to maintain oil pressure, especially in engines that are worn or operated under high stress.

What is the 'C' in the part number MB4569MC0.75?

The 'C' in the part number typically refers to the specific material composition King Engine Bearings uses for this particular bearing. This material is chosen for its durability and performance characteristics under engine operating conditions.
