Description
The Balmar 48-YP-IDL is an AltMount serpentine idler pulley for Yanmar JH engines, with a 2.75 inch diameter. It is used as part of a Balmar AltMount serpentine conversion on JH-series installations to route and tension the serpentine belt and keep it clear of adjacent engine components.
An idler pulley maintains correct belt wrap and tension across the drive, helping the serpentine belt run true and quietly. Fitting this idler on some engines may call for a longer serpentine belt, so check belt length against your specific installation.
