Komatsu Part BUSHING 707-52-91351
—
Product Overview
The 707-52-91351 BUSHING is a genuine Komatsu OEM replacement bushing from the 707 prefix series. Bushings are the replaceable wear surfaces at pivot joints throughout your machine's linkage, cylinder mounts, and undercarriage — they provide a controlled bearing surface between the hardened steel pin and the structural housing bore, absorbing friction and surface degradation so the more expensive pin and housing don't have to.

When to Replace
Replace the 707-52-91351 when rocking the connected parts reveals joint movement beyond the Komatsu specification; when the bushing bore is visibly oval or elongated from directional loading; when surface cracks, galling, scoring, or embedded debris are visible; when grease leaks past the bushing face during lubrication; or when the mating pin shows any visible wear ridge — pin and bushing should be replaced together.
