We've heard a thousand times that oil pressure and volume are keys to a healthy oiling system. We can use an oil-pressure gauge to monitor the effects of changes in our oiling system, but aside from ...

At the heart of your powerplant is the crankshaft, and this baby not only has to endure the entire rotating mass, but it is subjected to countless spin cycles at varying rpm. It's a tough life, which ...

The primary job of an engine bearing is to establish a low-friction interface for a rotating shaft. Most bearings today are half-round assemblies used around crankshafts, for example. While you might ...

Blueprinting has become an abused term. For those who build their own engines—or at least want to know how to check clearances like valve-to-piston on an existing engine—we will offer some techniques ...

Engine bearings play a vital role in the proper functioning of any vehicle’s engine. Their primary duty is to lessen the friction between moving parts, thereby preventing erosion and promoting ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...

Tapered roller bearings are designed to handle both radial and axial loads. They have a tapered inner raceway (called the cone), a tapered outer raceway (called the cup), and conically shaped tapered ...

Conventional compressor bearings - for example, leaded-bronze, rolling element or bi-metal bushings - will be significantly affected by wear in marginally lubricated environments at bearing locations ...
