Poorly compressor

[rtbcomp]

Reversing the pulley won't reverse the airflow. Consider the pulley as nut and the air passing through it as a bolt. Reversing the nut won't change the relative motion between the nut & bolt as long as the nut is rotated in the same direction in each case.

This is from the instructions for my Clarke 3hp belt-driven compressor



They recommend 1/2 metre clearance all round the machine, although they state this is for maintenance, but it would certainly help with air circulation.

Another problem with having a compressor in an enclosed space is that the pump will take in hot air, thus making the problem worse.

Red dot is the minimum level on mine.

The safety valve is always set slightly higher than the maximum operating pressure.

I'm glad that we've confirmed that the airflow is at least traveling in the right direction. I know Scott asked what is the cut off pressure in post 8, where you said it hadn't been adjusted since you got it, but what is that pressure that the pressure switch actually cuts it off.,

He said 9 bar in a later post. That is 130 PSI.

Mine was set at 120PSI. Later it started overheating and running long. I found it was now going up to 130PSI. Re-adjusted the pressure switch and no problems for the next 10 years.

Then the head bolts worked loose

Could anyone else confirm the oil level? i guess over filling it as just as bad as under filling it?

If you over fill it will just blow out the excess through the vent as mine is doing at the moment! due to thin clean oil not showing up on the sight glass

But looking at the photo your looks fine
