I recently purchased a 15 year old rivet gun that the previous owner never used. He had plans to build a Thorp, but never got started. The rivet gun looks brand new. I didn’t try it before I purchased it as the owner didn’t have a compressor any more.
A few weeks later I had a need for it and tried to test it out. Initially it didn’t run at all. I added some air tool oil and gave it a day or so and now it runs great, it just doesn’t turn off. There is some sort of leak past the trigger mechanism so if I hook up the air hose it is always on.
It is a US Industrial Tool model E3. I’m including a parts list that came with it. I’ve called US Industrial for some help and the tech support guy had never seen one before and his first suggestion was to buy a newer tool.
I’ve disassembled the handle and trigger assembly. Below are some pictures. In my mind the issue must be a leak past items 6 and 7. The metering valve (#10) is after the trigger so after the leak. I’ve made sure everything is clean and replaced the o-ring that is part of #6.
I’ll probably order replacement #’s 6 & 7. Unfortunately they are $30 each. It is disappointing that I didn’t get much help from the manufacturer.
Does anyone know something else that I could try? I’m about to give up on this.
Thanks,
Doug
