Basic Concepts of Changing Rod Bearings
Rod bearings are precision components that allow the crankshaft to rotate smoothly. Over time, these bearings can wear or become damaged, leading to reduced engine performance and reliability.
Changing rod bearings involves removing the old bearings and installing new ones. This requires disassembling the engine to access the crankshaft and connecting rods.
Advanced Features
Adjustable rod bearings: These bearings allow for fine-tuning of the clearance between the crankshaft and connecting rods.
Coated rod bearings: These bearings have a special coating that reduces friction and wear.
Tri-metal rod bearings: These bearings are made from three different metals, which provide a combination of strength, durability, and lubricity.
