Method for extending service life of CAT excavator carrier roller

First point, improve running-in quality


CAT excavator carrier roller running-in period has the characteristics of high wear rate, high friction resistance, high friction surface temperature and so on. The length of the service life of the excavator accessories depends to a large extent on the running-in quality during the running-in period. Doing a good job in the running-in period of the excavator parts can greatly reduce the wear of the parts during the running-in period, improve the surface quality of the parts, increase the wear resistance of the parts, and lay a good foundation for extending the service life of the machine. According to the characteristics of the wear of the excavator parts and the characteristics of the running-in period, to ensure the running-in quality of the parts, the running-in period of the excavator parts should be strictly in accordance with the requirements specified by the manufacturer. At the same time, during the running-in period, the rules for the speed and operating load of the machine should be strictly observed, and the maintenance of the machine should be strengthened.

Second point, start the machine correctly

The correct starting method of the excavator carrier roller has a direct impact on the service life of the engine. When starting, the time from when the crankshaft starts to when the oil reaches the cylinder wall is about 1 to 4 minutes. During this time, the wear of the pistons, piston rings, and cylinder walls was extremely severe. According to statistics, in the total engine wear, starting wear accounts for about 50%, and the engine wear during winter starts is greater; each time the engine is started, the wear of the piston ring and cylinder wall is equivalent to the normal working of the engine for 1 to 2 hours The amount of wear. The amount of wear during the engine starting phase is related to the length of the downtime and the level of the starting temperature.


After the engine stops working, the oil gradually drains from the friction surface. The longer the parking time, the more the oil is lost. The machine is parked for more than one night. The oil between the cylinder wall and the piston ring is almost completely deposited on the engine oil pan. There is a lack of sufficient lubricant film between the friction surfaces, and the new oil film needs to be formed within a certain time after the engine is started. Dry friction occurs between the metal surfaces of the piston ring and the cylinder wall, which greatly accelerates the wear of the cylinder wall and piston ring.
