I cannot figure out the luck either, I do take care of my tools, it is a PH2050 and it lasted less time than the FAR720 Ratchet. I do hope this inexpensive part fixes the issue within the air hammer.
Not sure why I opted for the 2050, I thought at the time it was the biggest they had....maybe the 3050 is a bit of a later version?
A bit ashamed to admit that at about the time this one let out ( 14 years ago, give or take ) I bought a Cambell Hausfield from Wal-Mart and in one form or another I have used it nearly Bi-daily and it has NEVER given me a lick of problem.
