Reviving Vintage Excavators: Reverse Engineering for Obsolete Parts

A North American equipment rental company faced a common problem: several older excavators in their fleet, including Kobelco SK120 and Hitachi EX100 models, required engine overhauls, but the original gasket sets were no longer available from OEMs. The company turned to Guangzhou Jusheng Precision Manufacturing for a solution.

Using advanced 3D scanning technology and material analysis, Jusheng’s R&D team reverse-engineered the obsolete gaskets, creating CAD models and producing prototypes within two weeks. The prototypes underwent rigorous pressure and temperature testing, confirming they met or exceeded original specifications. Full production runs were completed and shipped within 30 days.

The client reported, “Jusheng saved our vintage fleet from being scrapped. The new gaskets fit perfectly and performed better than the originals.” This case demonstrates Jusheng’s ability to support machinery of any age, preserving asset value for equipment owners.
