Counter Shafts and Gears

Counter Shafts and Gears are components of your car's manual transmission. The counter shaft serves the purpose of transmitting the input shaft movement to the output shaft by means of meshed gears. It is also known as a lay shaft. The counter shaft that is fitted parallel to the output shaft has gears of various sizes attached to it. These gears spin as the input shaft rotates, making the output shaft gears also spin.

The counter shaft has both forward and reverse gears. Each forward gear has a corresponding gear on the output shaft and they are meshed permanently. The reverse gear also has a corresponding output shaft gear and an additional idler gear that slides between them when the reverse gear is engaged. This makes the reverse gear turn in the opposite direction to that of the forward gears. Depending on the kind of automobile, there may be one or two counter shafts.

A counter shaft may fail due to bad bearings. Symptoms of a faulty counter shaft include a hard shifting and reduced engine efficiency. If you find any of the aforementioned indications, you should consider inspecting the counter shaft and its gears and replace them, if required. At Buy Auto Parts we stock a wide variety of counter shafts and gears for every car make and model.
