Description
Overview:
The Arm Assy Exhaust is the genuine Yanmar exhaust rocker arm assembly for L48-series single‐cylinder diesel engines, including L48 and L48N. Supplied under OEM/MPN 114771-11660, it is a precision‐machined steel component designed to transfer motion from the valve train to the exhaust valve, ensuring correct opening and closing under load. Built for reliability and long service life, it helps maintain stable combustion, smooth running, and proper exhaust flow. The assembly is engineered to fit the cylinder head and work with the existing valve gear, restoring performance where the original arm shows wear or damage. It suits compact construction and garden machinery powered by Yanmar L48 engines, providing a straightforward, factory‐correct replacement that preserves engine efficiency and protects downstream exhaust components.
