How to repair it IfLada car hasabnormal noise from the gearbox bearings?
- The repair methods for the gearbox buzzing sound are as follows: replacing the bearings, solving the gear problem, lubrication, and replenishing the gearbox oil, etc. After the bearings are damaged, the clearance will increase, resulting in a decrease in the mating accuracy, and the bearings cannot work normally, causing abnormal noise. If not controlled, it will further deteriorate. It is necessary to repair and replace the gearbox bearings in time.
- If the assembly is repaired, the center of the gears will shift, and it will also make a sound. In this case, the collapse situation should be inspected. If necessary, new ones should be replaced. During long-term use, due to frequent gear shifting, the parts inside the gearbox are inevitable to wear and deform, leading to faults such as difficulty in the gearbox, automatic gear shifting, and running noise, which affects the use.
3. Solutions For the dry friction sound of metal materials during the operation of small cars, touching the gearbox casing and finding it hot, this is also caused by the lack of lubricating grease or engine oil, resulting in a noise. Add oil or test the oil quality. If necessary, replace it. There is an abnormal noise in the neutral line. The noise disappears after depressing the clutch pedal.
The following introduces a gearbox bearing 50305 (6305N) suitable for Lada cars:
50305 (6305N) bearing is a single-row radial ball bearing with a groove on the outer ring. This part is used in many mechanisms and helps to reduce the frictional force during operation. It is open, so it is installed in closed units of units to prevent dirt and moisture from entering the system. The 50305 ball bearing can withstand high radial loads when the shaft rotates at high speeds.
50305 (6305N) deep groove rolling bearing belongs to the standard series and is an open ball bearing on both sides. The design features include the presence of a groove on the outer ring for the retaining ring, which can greatly simplify the installation and dismantling of the spare part.
The full marking of a standard bearing will look like this: 6-50305 GOST 8338-75 or 6-50305 GOST 520-2011, where:
* 6 – Accuracy class, always indicated in the front;
* 5 – The presence of a groove on the outer ring;
* 0 – Ball radial;
* 3 – Diameter series;
* 05 – Inner diameter code;
* GOST 8338-75 – Previous standard from 1975;
* GOST 520-2011 — New standard from 2011.
