Bluepoint 60 gal compresssor
says 7hp peak 135psi on side of it, no SCFM numbers stated. inline 2 cyl. no HP stated on motor tag. motor looks 2/3s the size of my 5hp phase converter motor?
i traded a JK lift install for this when it was like new, about 12 years ago (valued at $700 trade)
i have tried to change the oil and drain water before every winter. got away from me this and last year, ran out of oil seized.
broke free, ran for 3 weeks, seized again and blew flywheel off taper. i reinstalled, got free, got running, but noted 1/2 fill speed running longer, and found only one cyl getting hot (assumed broken rod)
went to HF today after research, they have a 5hp 2 stage i was looking at. McGraw, cast iron, pretty good reviews.
Instore price was 260, and it looks huge. look on the open box rack and there is the 3.7hp version 2 cyl single stage for 86$
looked like it sat on its side and oil soaked the box, otherwise new and unopened. inspected and grabbed it.
i had ordered a new 5" v belt pulley for motor and swapped that on (old was cerp belt) to correct the RPM of the 3450 motor.
Made a motor adapter plate to tank plate for new compressor pattern, scrounged a belt from belt pile, had to run to lowes for some 1/2" copper and new compression rings
old comp on 1 piston (pulled head and confirmed broke) was recovery time kick on to kick off 2min10sec
new compresor was 4min 59sec from 0psi to kick off pressure and 1 min 2sec for recovery time kick on to kick off!
win!
