What does the '+0.75mm' size designation mean for these bearings?

The '+0.75mm' indicates that these main bearings are machined 0.75mm undersize compared to a standard size bearing. This is used when the crankshaft journals have been ground down by 0.75mm during a rebuild to remove wear or damage.

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

Bimetal bearings, especially those with an aluminum base, offer good conformability to the crankshaft surface. This helps in maintaining an effective oil film, which is essential for reducing friction and wear between the bearing and the rotating journal.

What is the proper oil clearance for these bearings?

The proper oil clearance is critical for engine bearing performance. You should always refer to the specific service manual for your Suzuki J18K or J20A engine to find the exact oil clearance specifications and installation torque values.

About this part

Product Details

When you're rebuilding the bottom end of your 2007-2013 Suzuki SX4, especially with the J18K or J20A engine, getting the main bearings right is crucial. These King Engine Bearings are a bimetal set, meaning they use an aluminum base for good compatibility with the crankshaft. This particular set is machined 0.75mm undersize, which is important if your crankshaft has been machined to match this size during a rebuild.

King Engine Bearings are known for their well-built construction. The bimetal design helps ensure proper oil film formation, which is key to protecting your crankshaft from wear. Using the correct size bearing, like this 0.75mm undersize set, is vital for achieving the proper oil clearance. This clearance allows oil to flow and lubricate the surfaces, reducing friction and heat buildup.

If your crankshaft has been ground undersize during a rebuild, this set is what you'll need to achieve the correct clearance. Always refer to your vehicle's service manual for the specific oil clearance specifications and installation procedures.
