What does the 0.75mm undersize mean for these bearings?

The 0.75mm undersize indicates that these bearings are designed for a crankshaft that has been machined down by 0.75mm. This is common when a crankshaft has been repaired or resurfaced due to wear or damage.

What are these bearings made of?

These main bearings feature a bimetal construction with an aluminum silicon base. This material is chosen for its durability and ability to work well with crankshaft surfaces.

Do I need to buy anything else to install these bearings?

Typically, when replacing main bearings, it's recommended to also replace the main bearing cap bolts and ensure the crankshaft and bearing bores are clean. Always consult your vehicle's service manual for a complete list of recommended parts and procedures.

About this part

Product Details

This is a King Engine Bearings main bearing set, specifically sized at 0.75mm undersize, designed to fit your 1995-2002 Saturn SC1, SL1, SL, or SW1. Main bearings are critical components that support the engine's crankshaft, allowing it to spin smoothly within the engine block. When rebuilding or repairing an engine, especially if the crankshaft has been machined undersize, using the correct size bearings is essential for proper oil clearance and engine health.

These bearings are constructed with a bimetal aluminum silicon base, a well-known material for its good wear characteristics and compatibility with crankshafts. The 0.75mm undersize means these bearings are intended for use when the crankshaft journals have been ground down by 0.75mm to correct wear or damage. Using the correct undersize bearing ensures the proper oil clearance is maintained, which is vital for lubrication and preventing premature wear.

When installing these bearings, always refer to the manufacturer's service manual for the correct torque specifications and assembly procedures. Proper installation is key to ensuring these bearings perform as intended and contribute to a healthy, long-lasting engine.
