Topic: Shim pack in 21 stud babbit main V-8


ckh    -- 10-28-2013 @ 10:39 AM
  Does anyone have any experience or thoughts on the use of shim packs on the main bearings on a
21 stud babbit main block? The gentleman that poured the bearings in my block installed them. I haven't assembled the engine as yet and am having second thoughts about their use. I am concerned about oil leaking from the rear main into the clutch/flywheel area. Regardless, one of the shims for the rear main cap is broken and I will have to find a replacement should I decide to use them. It would probably be difficult to find. Would it be possible to remove the shim packs and re-align bore the bearings or would re-pouring the bearings be required? Would appreciate anyone's thoughts on this, especially experienced engine builders.
Thanks
