PARTS DESCRIPTION
Product Overview
Oil and fluid seals help retain lubricant or working fluid while limiting contamination at rotating shafts, housings, or joined components. The 4TNV86 Oil Seal for Yanmar 4TNV86 diesel engine applications (part number reference 119934-01800 129648-01780) is intended for replacement during engine or system repair where seal size and installation position must match accurately.
