I’d fix it right… that is a pretty nice compressor made by DeVilbiss, and it’s probably something trivial, like not having the counterweight in the proper location (or missing?). Also, according to the parts diagram, it appears that both connecting rods are identical (same part numbers), so I doubt that is the issue unless you are talking about something different.


PS: If you do put an external pump on there – the current one is running at the motors rated speed since it’s direct drive. To replicate with a pulley, you would just need 1:1 (ie: same size pulleys). If the pump you get needs a different speed, then there are plenty of calculators out there that will get you the correct sizes (such as this one over at the vintage machinery site).
