Installed a manufactures counter weight for my Chinese mini excavator Rippa R10-5. Talks you thru the steps on what I did to install it. I bought it back in January so I had to chase some threads with a tap, one I could only get about 3/8" in as the threads were damaged but I got it to work. I believe this is for a Rippa R10-6. For my machine the weight attaches to a piece of formed flatbar where as the 10-6 uses angel iron. Total time I worked on it was about 2 to 2-1/2 hours.
