HI can any one help. my main bearings have gone i have the hole engin striped down .my plan is to change all the bearings at the same time.how do i get the bearings out that are in the caseings.thay can only come out one way.any ideas

Place casing on a piece of wood with the main bearings facing down crank side down remove crank seal and gently tap bearings out using a brass drift being carefull not to damage casing! YOU can also use a press for removing them and refiting new ones! i would also get your conrod changed while your there as these wear the same as main bearings!
