Probably not an issue. Compressing air creates heat. Cylinders get warm, that's why there are fins and a fan. It is a matter of what you think is too hot. If you're worried, then use Anderol 755 or Secolube 800. Secolube 500 is equivalent to Anderol 750. Regardless of which oil you use, the temperature of the heads won't be lower during a run. Secolube 800 is for use in extended runs like in a business application and in tropical conditions. Like Miami.
@miamiguy2017 I’m not sure I understand exactly what you’re asking. My entire unit vibrates when in use. Can you feel anything loose that can be tightened on or around the third stage head on your Alkin?
Nothing feels loose its just that when the compressor is running i can see the 3rd stage vibrating, everything vibrates, im worried this could cause metal fatigue or excessive wear on the piston, i wish i could upload a video. Ive seen videos of alkins running and theres no vibration at all.
@miamiguy2017 Are you sure you're saying exactly what you mean? I'm having a tough time making sense of the last sentence in your previous post. If you mean exactly what you typed, please post a link so that we can see what you're describing. I'm not quite sure how you can own an Alkin W31 and claim or even think that one can run with no vibration at all, let alone determine this from watching a video.
