Default Power Hammer Air Valve Repair

For awhile now my Big Blu 110 has had air valve issues. When you first turn the air on the ram would go to the top of the stroke and stay locked there for 5 to 45 minutes. If it sat during the day for an hour or two it would do the same thing when you went to use it again. Very frustrating.
I had called Big Blu and talked with Josh several times and tried what they suggested. That didn't work so I called Josh and asked for a rebuild kit for the 5 way air valve. He told me the valves could not be repaired or rebuilt and a new one was $275 dollars.
In my mind it has allen head screws and end plates it has to be repairable so
I set out to prove Josh wrong. 2 hours and $2.47 later the hammer works like new.
Once in awhile even a blind hog finds an acorn;c)
I shot a video while I was at it so it might help someone else out in the future. Not a bad job to tackle at all.

Thanks, it's about crammed full. But not many wasted steps that way.

Nice fix on what they call a throw away item. My only suggestion is to add a couple drops of air tool oil each time you use it. Might make the O rings last longer.

Well done on the "no user\seller serviceable parts inside" repair.

A coalescing filter right at that valve with an oiler after the filter will do wonders for how long and how well pneumatic controls last. That fluid film is a good choice. Use a filter the same line size or one above. Don't try and do the whole system with one right at the compressor, it will help, more bang for the buck at the point of use.

I have a filter/oiler on the hammer. I've been using an air tool oil but maybe I need to switch to something different.

Sounds like you are ready to assemble rebuild kits as a sideline? Maybe Josh can send some customers your way? You already have a video showing them the "How Toos".
