ご依頼背景

We received an inquiry through our website regarding a Yanmar VIO30-6, reporting oil seepage during swing operations that was worsening daily. The swivel joint is a critical hydraulic component connecting the upper structure to the undercarriage; leaving oil leaks unaddressed inevitably leads to decreased performance and damage to surrounding parts.

The client requested an urgent repair to minimize downtime on their busy job site and asked for a thorough inspection to ensure long-term reliability. As the client was unable to leave the site, we arranged to pick up the machine in Takasaki City, Gunma Prefecture.

Additionally, we performed a comprehensive service including engine and hydraulic oil changes, as well as replacing the oil, air, hydraulic, and fuel filters. The machine was delivered in peak condition. We sincerely appreciate your business.
