This plate is equivalent to Sunbeam factory part references 6912 (and possibly 4022) and has corks of 7/32 ins thickness for most models for 1920x-35.
Other cork thickness can be supplied such as part number 4840 which has a cork thickness of 23/64 ins although this is often found to be too thick; please contact the spares team for further information at spares@marston-sunbeam.org .
Note: These plates should be soaked in automatic transmission fluid (ATF) for 24 hours before use. ATF is the recommended oil for the primary chaincase.
See the attached file for a dimensioned drawing.
