Description
Overview:
This bush is a heavy‐duty, non‐genuine replacement component for Yanmar mini excavators. Made from durable metal for long service life, it supports smooth rotational movement at pivot points and helps reduce friction and wear between the pin and housing. It is intended for use in diagram Positions 9 and 11 on applicable machines, including Yanmar B50 and ViO45 series. The bush measures 45 mm internal diameter (1.77 inches), 55 mm external diameter (2.17 inches), and 60 mm height (2.36 inches). It is identified by MPN 202 129, making it straightforward to match during maintenance. Use it to restore tight clearances, improve machine feel, and protect bores and pins during regular operation and load cycles on site.
