Technician A says the counter gear is actually several gears machined out of a single piece of steel. Technician B says the counter gear is driven by the clutch (main drive/input) gear and drives the mainshaft speed gears. Who is correct?

a. Technician A only

b. Technician B only

c. Both A and B

d. Neither A nor B

Option c. (Both Technician A and B are correct)

Explanation:

A transmission system consists of 3 shafts. The input shaft, the counter shaft, and the main shaft. The clutch gear always rotates with input shaft and is a crucial element of the input shaft.

The counter shaft is actually several gears machined out of a single piece of steel. The counter shaft may also be called counter gear or cluster gear. It is a secondary shaft that runs parallel to the mainshaft in a gearbox and is used to provide powers to machine components such as the drive axle.

The main gears (also called the speed gears) on main shaft (also known as the output shaft) are used to transfer rotation from counter shaft to the output shaft.

Hence in the light of above description, both technician A and B are correct.

The right option is C. Both A and B as the counter gear is a manual transmission gear with several gears on a rod to drive the mainshaft speed gears

Explanation:

The counter gear is a manual transmission shaft, with an opposite direction of rotation to that of the engine, consisting of several gears that are forged along a gear rod base and located at the bottom of the transmission system. It affords a connection from the transmission input shaft to the output shaft with control from the clutch as such it drives the output speed gears
