About this document

This 1941 factory WR flat tappet blueprint set gives detailled information on WR flat tappet specifications. These pages include precise
measurements of the angles of the flat tappet soles. These
had to be machined to match the WR tilted vales and straight cam lobes. Every
tappet is specific to a cam/valve: all shoe "soles" have diffrent angles. Click on the pics for a much larger version optimized for print.
