Establishing proper bearing clearance requires serious dedication to the science of reading a micrometer. Checking the crank means measuring each journal in at least four places to check for ...

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 ...

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 ...

Q: I just installed a 305 engine into my '86 El Camino. When I went to install the bolts on the torque converter, I pried it a little with a screwdriver until it mated with the flexplate and the ...

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 ...
