Rigid wheel barrow type compressor locks up
Ridgid wheelbarrow air compressor
The wheel that the belt attaches to seems to lock up. The bigger wheel is the one that locks up. I replaced the belt and checked oil seems ok. Runs fine till about 55 psi then starts locking up and making a terrible noise. What should I do? I blow out sprinkler systems so I need this equipment to run correctly and I'm running out of time. Start doing blow outs in next few weeks. HELP!!
