Hey all. I was wondering if any of you knew what I could use to get the old valve guide off of my Packer so that I can refit a new one on. Love the horn but one of the guides goes out about once a year. Normally I would just take it to the local repair shop but they are closed because of COVID and don't want to drive the hour and a half to the next closest repair shop. I was wondering if rubbing alcohol or even GooGone might be good but honestly I do not know. I have never done a repair on my horn so any and all advice is welcome and appreciated!

Post a photo of the piston, showing the valve guide clearly.

There is a technical contact via JP's web site.

There was a set of those included with my JP377. It seems like you just pull the valve, unscrew the valve button, pop out the old one by prying it upward, and push a new one in its place.
