Tsmg Drum Greasing Issue

[mgdoc8307]

Can too much grease in a L-drum or a C- drum slow it down so it won't be able to spin fast enough to keep up with the gun and therefore malfunction? Folks have talked about 25-35 pumps of grease in a L-drum; does the drum still function well after that much greasing especially in the cold wintertime? Please any thoughts or observations would be helpful as I am about ready to grease my drums. Thanks!

The problem with TSMG drums and how much grease to use is that you can't tell how much grease has actually gotten into the grease cavity until it's full. It's full when the grease comes oozing out of the six staked tabs surrounding the rotor.

 

After completely greasing all of my drums just last week, I noticed no functioning problems at all. The two that I function fired loaded, wound, and fired just the same as they did before.

 

The repro drums and WWII originals all took the same amount of grease. I've read here that the recent Cosby repro drums were not greased at the factory in Taiwan. If these were in fact empty, then so were the originals.

No, I don't think so. The originals I have filled required a few pumps less than the repros. But there was this small difference. This makes me think that the originals were hand packed with a small amount of grease...what the manufacturers thought would be sufficient to preserve and lube them, but not enough to slow them down.

 

I had also wondered if too much grease might impede function, but apparently it doesn't. If you think about it, the grease and spring metal is merely changing position as the drum rapidly operates. The contained volume is not changing. So there is no pressure change issue. But be sure to use grease which maintains the same general viscosity at low temps, to avoid the winter problems as the contents of that spring housing shift around. Not that many of us will shoot these expensive toys in an Alaskan combat situation at -40 degrees F.
