What does the 1.0mm oversize mean for these bearings?

The 1.0mm oversize designation means these bearings are larger than standard. They are used when the crankshaft journals have been machined down by 1.0mm to remove wear or damage, allowing these bearings to restore the proper oil clearance.

What is the advantage of a bimetal bearing with an aluminum base?

Bimetal bearings with an aluminum base offer good heat dissipation and conformability. This construction helps them adapt to the crankshaft and manage heat effectively, which is important for engine longevity.

Does this set include everything needed to replace the main bearings?

This is a main bearing set, which includes the bearings themselves. You will typically need to refer to your vehicle's service manual for specific installation procedures, including any required sealants or assembly lubricants.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings, and this Main Bearing Set for your Renault R9 or R11 is no different. If you're rebuilding the engine in your 1984-1987 Renault Alliance or Encore, these bearings are a critical part of getting your engine running smoothly again. They are a bimetal type, meaning they have an aluminum base, which helps with heat transfer and wear resistance.

This set is specifically sized at 1.0mm oversize. That means if your crankshaft journals have been machined down to remove wear or damage, these bearings will help you achieve the correct clearance. King uses a bimetal construction, which is a common and reliable choice for many engines, offering a good balance of strength and conformability to the crankshaft.
