How to lubricate the grinder gearbox: known means

Sooner or later, the grinder requires MOT. During this period, a preventive replacement of the lubricant of the tool reducer is carried out. A huge number of domestic and foreign lubricants are presented on the market. When choosing, you should focus on the manufacturer's recommendations and not engage in amateur performances.

Overview of lubricants

When buying, read the instructions that the developer says. Most often, the documents indicate the article or the name of the tool used for this type of device. To avoid problems in the operation of the tool, it is better to purchase the recommended product.

If desired, the lubrication is easy to make yourself. But in this case, it is impossible to make claims under the guarantee, and in the event of a breakdown, only yourself will be blamed.

Domestic production

Among the lubricants developed in Russia, it is worth highlighting Nanotech MetalPlak Electra. Designed for devices working with high load, has a high-quality composition for perfect rotation of the grinder.

Tsiatim-221 and Shrus are no less popular among domestic products. But when buying such funds, additional preparation will be required. Rather, they can be classified as homemade formulations.

Foreign production

If the grinder is branded, expensive, pay attention to foreign consumables. For example, for a Bosch tool, there are lubricants of the same name on sale. The product is packaged in small tubes of 65 grams and is called "gear lubricant". In a store, you will never be mistaken about what to take from the shelf.

Grinder gearbox lubrication

The moving parts of the angle grinder are most susceptible to wear. Gears and bearings are coated with oil from the manufacturer. But over time, it dries out and wears out, and the parts begin to contact each other, which leads to serious damage.

Features of lubricants for angle grinders

Oil material for grinders should have the following characteristics:

• does not have solid particles;
• turns into a liquid state at a temperature of at least 120 ° C;
• does not absorb moisture and protects parts from corrosion;
• viscous to gently wrap around gearbox parts.

The viscosity is selected according to the international classifier. The more mobile and powerful the tool, the more liquid the oil is chosen.

Grease Packing Procedure

For proper use of the oil, the gearbox is opened. Then the gears and all parts of the tool are cleaned of the old lubricant. This is due to the poor performance of angle grinders in such conditions. After that, a new one is applied and the quality of the work is checked. Assemble the gearbox and turn on the tool.

When a lubricant change is required

The average period for changing consumables is 1 year. This condition is relevant if the device is operated in accordance with the manufacturer's recommendations, without overheating. With increased work intensity, the shift period is reduced to six months.

How to properly remove old grease

To thoroughly rinse off the old compound, treat the gears in a solvent or work well with a rag. If using benzine or thinner, all parts should be thoroughly dried before reinstalling.

Do not install freshly washed gears into the gearbox. Mixing with new lubricant, gasoline and thinner will impair the performance of the device. The same will happen when mixing old and new lubricants.
