Gearbox — technical condition check (VAZ-2114)

Before proceeding to check the technical condition, check the oil level in the gearbox (see below, "Gearbox - Checking the oil level"). In a gearbox operated with a low oil level in the crankcase, intensive wear of parts occurs, which reduces its service life. In an inspection pit or overpass, we inspect the gearbox from all sides, make sure that there are no oil leaks at the junction of the crankcases and the cover, as well as through the seals of the wheel drives and the rod of the gear selection mechanism.

We make sure that the clutch release drive is in good working order and adjusted correctly (see "Clutch release drive - adjustment").

Pressing the clutch pedal, we engage all the gears in turn, checking the clarity of their engagement and disengagement. If necessary, adjust the gear shift mechanism (see "Gear shift mechanism drive - removal, installation and adjustment").

We set the gearshift lever to neutral and start the engine. Press the clutch pedal several times and listen to the sound of the gearbox bearings. It appears when the clutch pedal is released and disappears when it is pressed. Loud noise from the bearings indicates that they are worn out.

We check the operation of the gearbox while driving. To do this, first moving with acceleration and then with deceleration, we shift gears up and then down. We check the clarity of gear engagement and disengagement while driving, the operation of the synchronizers. We make sure that there is no crunching, knocking or other extraneous sounds when the gearbox is operating, as well as spontaneous gear disengagement when the load changes.
