These Brown seals are a very popular and widely used crankshaft oil seal including a PTFE sealing lip. While mounting pay special attention to the clearance between the seal and the adjacent bearing.
Many experienced Vespa mechanics see the crankshaft oil seal for the main clutch-side bearing as a major weak point of the large frame engine. A narrow fixing-bore surface combined with a relatively large contact diameter with the crankshaft. A combination that quickly tests both the quality of its production and installation. When this crankshaft oil seal fails then you are faced with the task of a complete overhaul of the engine.
