It is all back together. I used a pipe clamp to help get the belt tighter. It is now putting out 8.2 CFM that is better. Now on to my other compressor.
If you wanted to buy a two stage 175 psi 7-8 CFM cast iron pump compressor 60 gallon tank you would be paying around $900.
I think for the money I have into it It is a nice little compressor.
I always wanted to know how a compressor worked. To me it was worth the cost just to now know how a compressor works and bring one back to life. They do not make them like this anymore unless you pay big bucks.
It was a fun little project. I also feel better testing it out at 310 psi.
Last night I left it over night with 150 psi in it. I just checked it this morning and it still has 150 psi in it.
