Equipment Repair – Husky Air Compressor Won’t Exceed 40PSI

My Husky air compressor won’t exceed 40PSI. And it bothers me when my equipment stops working. So we’re going to dive right in and diagnose the problem. This stopped working years ago, but it has been sitting on my garage floor just waiting to be fixed. I decided to take it apart again and dig in to see if I could find the problem.

Disassembly of the Compressor Head

The compressor cover has four cap screws, which require a 5mm Allen hex bit to remove them. Once removed, you can identify the motor, the flywheel, the piston crank arm, the piston, and the compressor pump head. There are four cap head screws and nuts that secure the compressor pump head assembly to the mount. I also had to remove the compression fitting holding the outlet tube. Once these four screws are removed and the compression fitting is removed we can remove the compressor head assembly.

Diagnosis of the Problem

After the pump head is removed you can pull out the valve plate and inspect it. You can also inspect the piston valve. I looked at the piston valve and it seemed fine as shown in my video. However, when I inspected the valve plate, I could see a chip out of one of the valves. This would explain why the pump never exceeded 40PSI.

Purchasing Replacement Part

I searched for Pump OL195 J4 and found Master Tool Repair. My pump head assembly is the old style but I ordered the new style assembly. I hope it is a drop-in replacement for it. I filmed the disassembly of the pump head and my diagnosis. That will be part of a larger video once I fix the compressor.
