During the break-in period of track assembly components, galling can occur between the components during use. The components include a pin that is received within a bushing and alternatively a sleeve bearing between the pin and the bushing depending on the load. A method to prevent or reduce galling includes applying a coating of zinc phosphate and a low-friction layer on top of the zinc phosphate. The low-friction coating can be made of WS2 (Tungsten Disulphide), BN (Boron Nitride), MoS2 (Molybdenum disulfide) or PTFE (Polytetrafluoroethylene) and deposited during a mechanical treatment.
