Lubricants

Lubricants protect metal parts from premature wear resulting from friction of the parts against each other.

Types of lubricants by performance characteristics (API)

• NLGI consistency number (NLGI grade) 000. Penetration at 25 °C: 445-475
• 00. 400–430
• 0. 355–385
• 1. 310–340
• 2. 265–295
• 3. 220–250
• 4. 175–205
• 5. 130–160
• 6. 85–115
• 7. below 75

Types of lubricants by the NLGI grade

• NLGI 1. The composition includes thickening agents based on lithium, lithium calcium and lithium complex, micro-gel, calcium and polyurethane. Dropping temperature - between 80 and 250 °C.
• NLGI 2. May contain both organic and inorganic thickeners. Temperature between 80 and 600 °C. May contain graphite.
• NLGI 3. Contains lithium and lithium-calcium thickeners. Temperature - 180 °C.

Functions of lubrication

The basis of almost any lubricant is mineral oil with thickeners often added. Its viscosity is determined by the number and the type of additives. It also contains additives that ensure protection. This structure makes it possible for the lubricant to stay inside the non-sealed unit without flowing out and protecting parts from wear. Also, the functions of the lubricant include:

• protecting parts from corrosion;
• ensuring proper operation of specific systems of the vehicle;
• increasing the service life of the component, and
• protecting components of the system from overheating.

Tips on using and replacing lubricants

Some lubricants do not require replenishment until the complete wear of the component. In this case, they are replaced together with the installation of a new component. However, lubricants of bearings, water pump, chassis or the steering mechanism should be replaced during each maintenance.

The schedule for replacing lubricants is specified by the manufacturer of the specific component. To ensure efficient operation of the unit, observe certain rules of replacement:

• remove the old lubricant completely;
• fill only the quantities of the lubricant that are specified in the user manual for the component;
• use the lubricants recommended by the manufacturer.
