In this guide, we will walk you through the essential steps and expert tips to install engine bearings correctly, helping you achieve the reliability and performance you demand from your engine.

Engine bearings play a crucial role in ensuring smooth operation and longevity of your engine. Whether you're an engine builder, a DIY enthusiast, or just curious about what's under the hood, understanding the terminology associated with main bearings & rod bearings can be incredibly beneficial. Let's explore the key terms related to three main types of engine bearings: Straight Shell Bearings, Thrust Washers, and Flange Bearings.

In order for bearings to maintain a stable oil film, which is vital to their life, there must be a perfect match with clearance size, oil viscosity, engine operating  temp, crank surface finish and geometrical alignments. General rule of thumb for determining oil clearance is .001 of clearance for every inch of shaft dia. Ex .001 x 2.00 shaft dia.  = .002 oil clearance.  For clearances smaller and larger than the rule of thumb ,refer to the factors listed below:

Running the proper clearances for your rod bearings is a very important factor when building an engine. It is critical to get your rod bearing clearance right. Too much clearance and the spinning crank will fling all the oil out of the area between the bearing and the crank journal making the engine suffer from low oil pressure. This will cause metal to metal contact between the two which will result in spinning a rod bearing, destroying the rod, crank and possibly the whole engine. Too little clearance and the rod bearing might make hard contact with the crank journal and bind, damaging the bearing, causing it to spin, with possible terminal consequences to the engine.

Running the proper clearances for your main bearings are some of the most critical things to control when building an engine. Having the correct clearances means the difference between premature wear, friction, failure and having a long-lasting, power-producing engine.

It is critical to get your main bearing clearance right. Too much clearance and an engine will suffer from low oil pressure. In severe cases, the oil pump won’t be able to keep up with the oil bleeding from the large bearing gap due to centrifugal pumping, the hydrodynamic film will break down. Too little clearance and the crank might bind and make metal-to-metal contact due to runout in the crank. This will result in a lot of friction and damage to the bearings and crank as well.
