Re Lubricating "sealed for life" MG725

[outdoorsman310]

I have the MG325 and 725. I think they are great guns, but the anvil portion is sealed "for life" with redline synthetic oil.
The anvil on my 725 felt somewhat dry and clanky so I took the gun apart. I removed the old oil that had metal particles in it, cleaned the hammer and anvil, applied a small amount of moly paste to certain parts of the hammer portion, and put some ATF in that smelled similar to the old oil. I am not sure if the atf is compatible with the seals, but time will tell.

Oh, and brake cleaner makes the letters disappear on the case. don't do that

Unfortunately I did not. The 325 still feels smooth and I will take pics or make a video of changing the lube.

I took the rear cover off, put oil around the motor sleeve and lightly tapped the assembly out with a brass hammer.then the motor and anvil portion seperate and you can change the oil.

Thanks. Really looking forward to that.

What caused the metal shavings? Did you visually see where they came from? Isn't there a warranty for that? Don't they use a specific lube also?

I am not sure. not so much shavings as specs of metal. I think they may have been from wearing in? I wonder if the lube they use is available?
