Precision engineered big end bearing shells equivalent to Lister part numbers 5-1/D18 and 5-1/D19.
Five sizes are available, standard for a 2.5' crank pin and then in 0.010" increments for those who need to compensate for a worn crank pin after a re-grind.
Please purchase shims separately to enable you to adjust the nip/clearance which should be no more than 0.003".
We strongly advise that the bearing clearance is checked with a plastigauge kit which is available on the Plastigauge page.
