I had ordered and received replacement crankshaft-connecting rod bearings. Dan and I took a couple hours to put the compressor back together. Dan had some STP type stuff to put in the bearings during assembly. We put the flapper plates back together, bolted it all together, filled it with oil, put the fly wheel on, and …. it works and it is much more quiet. So far so good. The worn bearings must have been rattling around.
