My old Monkey Wards 2 piston, single stage, 6 gallon (guessing), 1 hp,
120V air compressor runs as hot as 180 degrees on the cylinder head
when I'm using it a lot. Is that a normal temperature for this kind
of compressor?


when I'm using it a lot.

If you run it a lot higher than the rated duty cycle it's gonna be
abnormally hot I would think.
