Insert bearings can't do this. 4 Attachment(s)
These pictures I am posting represent an interesting aspect of Babbitted bearings versus inserts.
This engine was done by another shop and though the babbitt work was Ok. The dirt impregnation from assembly and running tells another tale. This engine has 1200 miles on it, reason it came to us is customer wants to put stroker crank in it. It's interesting since there's always two sides to the arguement of insert versus babbitted bearings. These pictures show how well babbitt is able to "Digest" the dirt in the engine and still perform with a bearing surface of sorts. The debris is glass beads with a mixture of iron and brass. Naturally this is worst case senario but even still the babbitt survived. I couldn't say that for inserts or the crank in same situation. |
Re: Insert bearings can't do this. For 1200 miles that looks like sabotage , buy that man a blow nozzle .

Re: Insert bearings can't do this. I can see where the iron and brass could come from, but where did the glass beads come from.

Re: Insert bearings can't do this. It's essential to wash out a block after the machining has been done. I use Dove dish soap and a spoke brush on the cylinders, and a dishwashing brush on the crankcase, then hose it all down good with fresh water, and finally blow it out with compressed air. I might miss some, but I've never noticed anything.
