An idler gear is a gear wheel that is inserted between two or more other gear wheels. The purpose of an idler gear can be two-fold.Firstly, the idler gear will change the direction of rotation of the output shaft.n idler-wheel drive is a system used to transmit the rotation of the main shaft of a motor to another rotating device, for example the platter of a record-reproducing turntable or the crankshaft-to-camshaft gear train of an automobile.
A gear stick (rarely spelled gearstick), gear lever (both UK English), gearshift or shifter (US English) is a metal lever attached to the shift assembly in a manual transmission-equipped automobile and is used to change gears. In an automatic transmission-equipped vehicle, a similar device is known as a gear selector. A gear stick will normally be used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels.
