I would like to clean the oil passages in my engine. But I do not want to re Babbit all the bearings if i dissaseble the engine. Can this be done without new babbits.

James,
Are you talking about rod or main bearings?
Are the bearings "inserts" (removable for rebuilding) or are they poured in place?
I have cleaned babbit bearings and especially the pipes/tubes that lead from the grease cups to the main bearings. One engine had a "rifle-drilled" crankshaft to allow grease from the front grease cup to travel in a double "L" pattern and grease the rod bearing. You had to position the hole in the crankshaft just over the spot where the grease cup pipe dumped out.
The "L" passage was completely clogged with hard deposits that I had to drill out but it worked out fine when running.
Just use common sense. |

Thanks for your post thomas. The bearings would be rod and main. I have no idea at this point if they "inserts" (removable for rebuilding) or are they poured in place?. The engine is a Scripps 4 cly. 60 horse power I beleive that it is serious 30. |

James-That sounds like a newer engine that would have an oil pump? You could probably force a cleaning fluid through the oil pump lines using a
hand pump. This would probably wash out anything in any of the lines or passages. Was this oil line cleaning something you were told was necessary? Are you planning on rebuilding the engine? If you are trying to "de-gunk" it and
then refill with new oil and see how it sounds
you should still remove the crankcase to clean it
out and just look at the rods etc. |
