Komatsu Part BUSHING 419-43-17590

—

Product Overview

The 419-43-17590 BUSHING is a genuine Komatsu OEM replacement bushing from the 419 prefix series. Bushings provide the controlled wear surface at pivot points — absorbing the friction and surface degradation that would otherwise damage the pin and housing bore.

Part Number: 419-43-17590 Part Name: BUSHING Part Type: OEM Komatsu Replacement Bushing Availability: In stock

When to Replace

• Rocking the connected parts reveals movement — clearance between bushing and pin has grown beyond the design limit
• The bushing bore is visibly oval or elongated rather than round
• Surface cracks, galling, or scoring visible on the bore
• Grease leaks past the bushing face — the clearance gap has opened too wide
• The mating pin shows any visible wear step
