Hi everyone, I have hardness data for bushing & pin of ITM & Berco undercarriage. For ITM bushing, the surface hardness = 55 HRc, case depth = 55 HRc, core = 52 HRc For Berco bushing, the surface hardness = 60 Hrc, case depth = 50, core = 40 HRc. Do you have any data/information about the performance of ITM & Berco on Komatsu PC 1250. which one gets the most failure problem?
