Engine Honing Services Equipment
Our Sunnen engine honing services equipment uses mandrels for all the popular wrist pin and rod journal sizes,
This enables our highly skilled engine machinist to fine tune rod bearing clearances that will compensate for small differences in rod journal size and bearing thickness achieving necessary equal bearing clearances.
In this video one of our machine shop machinist is resizing the larger end of piston rods to allow for proper oil clearances. In this particular case factory piston rod bolts were replaced with stealthier ARP bolts and required 4 thousandths of an inch be removed from each piston rod end.
