Backlash, pinion depth, tooth pattern, pinion and carrier-bearing preload—what does it all mean? When used in reference to an automobile, these terms usually apply to the rearend (or differential) and ...

Installing new gears and differentials is one of those jobs that even skilled mechanics and fabricators typically don't like to tackle at home for many reasons. Setting up gears requires specialized ...

Tapered roller bearings can be fixed and preloaded using shims and an end cap. There is a setting procedure to ensure the desired preload is achieved and the amount of end play (axial clearance) is ...

Last month we dug deep into the 8.75-inch rear end assembly from our 1971 Dodge Challenger R/T project. Like the vast majority of Mopar muscle cars, our 383 automatic Challenger came equipped with the ...

An accurate, mounted preload setting can be achieved for bearings in a 2-TS spindle to meet speed, stiffness, and accuracy requirements that will promote high-quality surfaces finishes for machined ...

Preload is the minimum amount of force that ensures smooth and tight movement between parts in a power-transmission assembly by eliminating gaps and slop. A myriad of mechanisms require preloaded ...

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 ...

Transmissions and transfer cases are connected to axles using driveshafts, and those connections use U-joints and yokes. While the typical wear item in these links are the U-joints, there are times ...
