Here's the deal. I recently scored a two-cylinder Wayne air compressor pump
on Ebay to replace a Campbell-Housefeld pump. This was a lot cheaper than a
replacement C-H pump, and is in good condition, having had only limited
garage use over the years. It did not come with a flywheel, but the remains
of the C-H pump has one. The only problem is that the seller of the Wayne
pump says that the original flywheel turned in the opposite direction to the
C-H (and every other compressor pump I've looked at this evening on Ebay).
This is an old, but very high quality, industrial pump from the 60's. I can
find no trace of Wayne any more to ask. I don't think it's the same company
as Wayne water pumps.
This is a small cast iron pump, very similar in size to most 1-3 hp
compressor pumps. It has poppet valves, not reed valves. I doubt very
seriously that it has an oil pump inside. The only reason I can think of
that it might not be good to turn it the wrong way is if there were an oil
slinger, or some oil pickup on the con rods or crank to direct oil, and this
might not work right if turning in the opposite way to the design. One
other possibility might be labyrith oil seals, but the only seal visible
looks like an ordinary lip seal.
Can anyone think of a reason why this couldn't be turned CCW instead of CW?
Has anyone ever been inside a pump like this? Anyone actually know for
