Bought a Black Diamond 60 gallon compressor about a year and a half ago and the compressor started hammering.. In this video, I replace the bad factory compressor with one from Harbor Freight. Compressor prices are through the roof now so I was looking for the most economical way to get this thing going. Seems that no matter what brand you look at now days, the reviews are horrible.. Even some of the top brands are having issues it seems!
