What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are 0.020 inches larger in diameter than standard size. This means they are designed to be used when the crankshaft journals have been machined down by 0.020 inches, typically to remove minor imperfections or wear.

What is the advantage of bimetal aluminum base bearings?

Bimetal bearings with an aluminum base offer a good balance of wear resistance and thermal conductivity. This helps them maintain proper oil clearance and manage heat effectively, contributing to the overall durability of the engine.

Are these bearings a direct replacement for all 1.6L 8V Ford engines?

These bearings are specifically designed for the Ford 98Ci 1.6L 8V engine found in certain Ford Escort and Mercury Lynx models from the early to mid-1980s, as well as other compatible vehicles listed. It's important to verify your engine code and vehicle fitment before purchasing.

About this part

Product Details

King Engine Bearings is known for making solid engine components, and this main bearing set is no different. If you're rebuilding the engine in your 1981-1985 Ford Escort, or a compatible Mercury model, these bearings are built to handle the job. They are designed to replace your original main bearings, which are critical for supporting the crankshaft and keeping it properly aligned within the engine block.

This particular set uses a bimetal construction with an aluminum base. This type of material is chosen because it offers good wear resistance and helps manage heat effectively, which is important for maintaining consistent oil film and preventing premature wear. The set is also sized at +0.50mm, meaning it's intended for use when the crankshaft journals have been machined down by 0.020 inches to clean them up or account for previous wear. Using the correct undersize bearing is key to achieving proper oil clearance and ensuring the longevity of your engine rebuild.
