Description
Overview:
This exhaust assembly is a replacement part for Yanmar single-cylinder diesel engines, including the L90 and L100 series.

The mounting pattern is designed to match the original for straightforward fitting. Non Genuine Part. Replaces OEM No. 114970 13550 and variants shown below. Key mounting dimensions are provided to help confirm compatibility before installation.
