Quality aluminium bearing shims, available in three thicknesses to allow for the fine adjustment of your Lister CS crankshafts end float. Particularly useful for anyone wishing to convert their genuine Lister engine to the taper roller bearing system as this conversion necessitates the shimming up of the bearing carriers away from the crankcase by approximately 0.020" either side.
Two types are available, small for the old style engines with four mounting studs points on the tear drop shaped bearing carrier and large one for the Indian variants usually found on engines fitted with taper roller bearings using bearing carriers with five mounting stud points.
These shims should ideally be inter spaced between gaskets of the same type made from paper which are supplied in our gull gasket sets or they can be used without paper gaskets if every layer is bonded with a jointing compound such as Heldite.
