A set of precision engineered big end bearing shells equivalent to Part No. 574-10320, comprising shells 8-4-26 and 5-1/D19, suitable for Lister CS 8-1, 16-2, Start-O-Matic and all the CS engines fitted with the heavy kidney holed flywheels.
Complete with oil grooves cut in the white metal for lubrication purposes. 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.
