Please receive herewith:- LeC.4629 showing the spring drive and slipper flywheel with increased inertia and damping. The damper plate has been made with a solid centre to overcome fractured pieces. On this scheme we show cork inserts for the flywheel damper, but other designs can be made here as there is now more room available for fabric discs. Also herewith:- LeC.4694 cork insert friction disc for slipper flywheel. LeC.4632 showing the wheelcase for the above. LeC.4692 showing the Tecalemit oil pressure filter.
