M60A1 RISE Passive vs M60A3

Does that mean clean it? Why did you need to take off the shroud?

 

Punching the tube requires removing the bore evacuator to make sure the little vent holes are cleaned out. These allow the gases from the fired round to enter the bore evacuator from the gun tube. The next round sucks the gases out of the bore evacuator and out the end of the tube. Then the gases from the second round enter the bore evacuator. The gases from the final round eventually dissapate out of the tube.

Any way, in order to remove the bore evacuator, you have to take off the forward portion of the thermal shroud. Then you have to clean the inside of the bore evacuator to get all the soot and gunk out of it. We had like gallon jugs of a bore cleaner called Break Free that helped remove the carbon build up.

In this old photo of my M48A5, you can see in the upper right hand photo that the bore evacuator has been removed and is sitting upright on the right front fender of the tank.

Thank you for the explanation. That is really interesting.

That is fascinating.  I wish I was tanks in the Corps...

I spent some time reading about fume extractors this afternoon. Kind of ingenious devices.

I guess Rob if you don't keep those little holes open it can kill you.

The turret vent motor was always on when you were firing. Helped keep the gases to a minimum, but all tankers enjoy the smell of cordite from a freshly fired main gun. It smells like victory! It's a sharp gun powder like smell.
