Odd you should mention that. I was a little concerned about it, and the folks over on Ron's board pointed it out as well. One of them suggested swapping ends on the cylinder and dump frame to get the lift point further from the hinge point, which would increase leverage. Dieselrider mentioned that, sHan mentioned the cylinder being too flat to have a starting point.
Turns out both DR and sHan were right: Reversing the lift point and the fixed point GREATLY improved the action, and lowering the fixed end of the cylinder to increase the angle was necessary.
The first thing I did was take the dump frame off and swap it end for end. I cut the original hinge plates off, added a new crossmember in the appropriate spot and welded the hinges back on.
Then I duplicated the fixed mount that I used on the front frame member and welded it to the rear frame member in the same manner. Hooked up the pump and tried it and....Oh, shit. All it would do was try to spread the frame. So much for Plan B.
I jury-rigged an extension to lower the fixed end of the cylinder about 6" and tried it again. MUCH better. So I cut some new pieces and welded them in place, pinned the cylinder in and tried it again. Okay, but it was flexing the crap out of the back frame member due to the leverage from the dropped pivot point. Crap. Again.
Scrounged around and found some 1/2 x 1 flat stock and triangulated the lower pivot point back the the frame. Fired up the pump and VOILA!
