Sorry I'm late responding to this thread. We have been using slightly modified (ground down) drag link sockets in our reman shop for years. Every K and L body Copeland gets new sight glass parts. If you need any components like gaskets or the retainer nut or the glass itself, send me a note, I'm glad to help.

His excuse was that he "heard" that once it starts leaking you can never really stop it so you should replace the compressor. This is complete BS. It's a mentality, IMO. Some guys are parts changers. New valve, new compressor, new unit, new motor, new, new, new, new, new... Then you've got some guys, old timers particularly, that won't replace ANYTHING. They'll spend more time and money fixing something than it's worth. I've seen a guy spend 3-4 hours rebuilding a motor that cost about half of his labor to purchase and would have taken less than an hour to install. A sharp tech will repair what can be repaired and replace what must be replaced, considering all factors in the process. Equipment reliability, equipment age, cost, downtime to repair, etc.

Have you tried getting one of those out after 10 years of being sweat on? I tried once and failed miserably. The next time I changed the entire sled. Wrong? I don't think so, you can have a critical machine be handicapped because of this. Give them the option? Absolutely but everything comes with risk and the customer had the pleasure of making that call. That is certainly a special circumstance. We all have these sometimes.

I have tried to stop leaks at sight glasses as well. Sometimes it works sometimes it doesn't. Same goes with this customer and valve plates. They don't want to here it.

That is like replacing your car engine because the oil filter is leaking because it is loose. In my case they would be robbing thyself. They buy there own compressors. I wish I could keep the replaced ones but obviously they want them back for the cores.

There is a tool for the bigger ones, it fits on a 3/8 socket and looks like a flat blade screwdriver?
No quarters?? take the knock out if the electrical box.. Cause that quarter is definitely gonna grab useless after your done with it. Sent from my SGH-T999 using Tapatalk 2
a quarter, that is funny! I;ll try it.
Yeah, this one was on a hussman dipping cabinet. One of our guys has been out a couple times and gassed it up, but now the owner wanted us to find the leak. So I got some hits around the glass and had small bubbles during run, but not on off cycle. Obviously, the leak check was during off time, lol.
I use a quarter with a lines man plier. does the job. Sent from my SGH-T999 using Tapatalk 2
They always have me replace the compressor when that happens. Personally I find it a waste of money but there buying the compressors. I would find a piece of flat bar stock that fits the cut outs. You would not believe how many I've changed because of it. The next most leaking point I find at the high side service valve.
Tool for copeland semi herm sight glasses Does copeland make a tool to remove/replace the sight glass in their semis? We run across leakers, my boss made a tool out of a washer to pull them out.......it works, but is getting kind of worn. We find them leaking periodically. Thanks.
