What does the '+1.0mm' size designation mean for these bearings?

The '+1.0mm' indicates that these bearings are 1.0mm larger in diameter than the standard size. This is typically used when the crankshaft journals have been machined down (ground undersize) during an engine rebuild to remove wear or damage. These bearings are designed to bring the oil clearance back to the correct specification.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This type of bearing material is well-known for its good load-carrying capacity and compatibility with engine oils.

Do these bearings come with installation hardware?

This listing is for the main bearing set only. Installation hardware, such as main cap bolts or oil seals, are typically sold separately. Always refer to the manufacturer's instructions for a complete list of required components for your engine rebuild.

About this part

Product Details

If you're rebuilding the engine in your 1981-1985 Ford Escort, getting the main bearings right is crucial. These main bearings from King Engine Bearings are specifically made for the 1.6L 8V engine found in your car, and they're sized 1.0mm undersize, which is important if your crankshaft journals have been machined down during a rebuild.

These bearings use a bimetal construction with an aluminum base, a common and reliable material for engine bearings. This design helps them handle the loads and heat generated by the engine while maintaining proper oil clearance. Ensuring the correct oil clearance is vital for engine longevity, and using bearings that are the right size for your machined crankshaft is a key part of that process.

When you're putting your engine back together, using well-made bearings like these from King Engine Bearings will help ensure your rebuild is solid. Make sure to follow the manufacturer's installation instructions carefully, especially regarding cleaning and lubrication, to get the best results from these main bearings.
