The high pressure gun trigger turned up broken today, which it the first time for me. I was thinking that I could take it apart and just replace the trigger. Looks like you can not replace it.
I then decided to try and fix an old broken gun. I used my easy out and it was not very easy getting it out. In fact the easy out broke, which is another first.
To replace the trigger, just drive out the stainless pin where it pivots. On the gun that had a broken discharge fitting, what probably happened is that your extractor was too long and grabbed inside the housing, right through the broken fitting. You’ll have to grind or cut some of the extractor off for it to work right.
