    Default excavator hammer top plate

    Customer bought a hammer for his excavator to help him keep working with the heavy frost. Pin location needed to be modified to fit his quick coupler. This pc. has been modified at least once before. It had extra bushings with it also.

    What I did was measure the difference I needed in pin centers & cut out the one location off center. Flipped pcs around & left to right. This moved the centers to where I needed them. He gave me 2.25" hot rolled bar to use for pins & the bushings were 60 mm (2.359"). So I wrapped the pins where they go through the bushings with .050" sheet. This gave me a tight fit. I also had to make up 3/8" spacers on each inside to shrink it 3/4" total to fit tightly side to side. Welded everything solid as per customer.
