Komatsu maintenance notes (quick guide)

• Early-life greasing: For excavators, Komatsu guidance calls for greasing work equipment pins every 10 hours for the first 50 hours, and greasing again after water work.
• Clearance control: Komatsu linkage manuals commonly specify pin–bushing clearance targets and a typical service limit around 1.0 mm for many joints, often managed with shims.
• Tracked machines: For undercarriage track joints, pin/bushing turning is condition- and wear-window dependent; abrasive sites can accelerate wear substantially.
