Abstract
Researchers often want to develop their experiments in terms of wide range of testing conditions and results possible to acquire. One way to achieve this is to adapt existing testing equipment to new requirements. This paper proposes a method for extending the capabilities of the T-01M tester with a pressure lubrication system of a pin on disc contact, its construction and adjustments. Tribological tests carried out with the presence of a lubricant showed the correct functioning of the modified tester. We obtained several variables for the selected friction pair and friction parameters in the lubricated joint: friction force, friction coefficient, mass wear, friction work, wear intensity and specific wear. Verification tests confirmed suitability of the tester modification, adapting it to friction and wear tests in a lubricated contact. The expanded stand can be used (in the future) for tribological tests of lubricated frictional pairs to measure friction, wear, friction pairs temperature and to compare used lubricants.

Summary
Many different tribological testers are used. They vary in ways of setting parameters, measuring and recording results. The researchers often want to make a slight change to the testing conditions or measure other variables. They are forced to buy a new laboratory equipment. A solution to this type of problem may be outsourcing to other research centres, which is not always beneficial (time, availability, limited control, etc.) Another method of expanding research capabilities is to modify already existing research devices. The T-01M tester is designed to assess the tribological properties of the friction pairs machines and devices. Tests were carried out to check the functioning of the modernised test stand These were the requirements for the lubrication system: - easy assembly and disassembly of system components and the possibility of easy disassembly of counter samples;. - maintenance-free operation during a multi-hour test; - circulating lubrication with liquid lubricants while ensuring cooling of the friction junction; - adjustability of the amount of lubricant supplied; - continuous supply of lubricant by a pump; - tightness of all elements of the lubrication system; - disposing of the lubricant excess from the friction junction; - possibility of lubricant injection point adjustment
