Komatsu Part BUSHING 569-46-11181

Product Overview

The 569-46-11181 BUSHING is a genuine Komatsu OEM replacement bushing from the 569 prefix series. Bushings are the replaceable wear surfaces at pivot joints throughout your machine — they provide a controlled bearing surface between the hardened steel pin and the structural housing bore, accepting the frictional wear that would otherwise damage those far more expensive components. When clearance exceeds the design specification, a bushing replacement restores the joint to factory dimensions at a fraction of the cost of replacing the pin or repairing the housing bore.

When to Replace

The physical symptoms of a worn bushing are straightforward to detect with basic inspection techniques. Grab the connected components and rock them — any movement beyond the Komatsu specification indicates the clearance between the bushing and pin has grown beyond the design limit. When the pin is removed, examine the bushing bore — if it's visibly oval, elongated, or shows surface cracking or galling, the bushing is done. Check for grease leaking past the bushing face rather than flowing through the designed clearance path — this is a reliable indicator that the gap has opened too far. And always inspect the mating pin: if the pin shows any visible wear ridge or surface damage, it should be replaced together with the bushing, because a new bushing installed on a worn pin will not achieve the correct clearance or service life.

Installation

1. Confirm 569-46-11181 in your Komatsu parts catalog
2. Press or drive out the old bushing using a driver with the correct pilot diameter — avoid scoring the housing bore
3. Clean the housing bore completely — all old bushing fragments, dirt, and debris must be removed
4. Inspect the mating pin — replace it if any wear ridge or surface damage is present
5. Press the new bushing to the correct depth — ensure any grease holes or grooves align with the housing
6. Apply assembly grease to the bushing bore before inserting the pin
7. Pump fresh grease through the fitting until clean grease purges at the seals, then cycle the joint and re-grease
