Buick Straight 8 Engine Bearings

[Jack Worstell]

 

I have never been able to figure out Buick straight 8 engine bearings.

But I think (??)............

 

            Up until about 1937 main bearings were babbit

            From about 1937 to late 1940s the main bearings were what I would call "non-precision inserts"

                   That is they had to be line bored and/or shimmed

            Starting in the late 1840s the mains were precision inserts....you turned down the crank

                    then took careful measurements and then slipped the insert bearings in without shims

                     and ( usually )   no need to line-bore

 

           Rod bearings were babbit up until the late 1940s............they had shims

                    In the late 1940s Buick went to precision inserts for the rod bearings

                    Buick didn't use non-precision inserts for the rod bearings

 

So.....how close is this to being right  ???
