Center Case Gasket 70-77 Ossa Dmr Explorer Mar Pioneer Sdr Stiletto Tt 175 250 Vintco OW-991-606

Description

Centre case gasket for Ossa models from 1970 to 1977, designed for engines using the small style crank. This is a reproduction gasket for DMR, Explorer, MAR, Pioneer, SDR and Stiletto applications. On Ossa Explorer models, two different centre case gaskets were used depending on crankshaft style: the older small diameter crank uses OW-991-606, while the newer large diameter crank uses OW-123-215. In many cases, the crankcases must be split to confirm which gasket is required.
