Whats wrong in the plans?
The most memorable problem was the woefully inadequate support for
the boom pivot cylinder. I had to significantly beef up the weldment on
the boom pivot after breaking it off. I stayed at 1500psi, too.
Also, I switched from a heavier engine to a Tecumseh 10hp and I needed
to add lots of
ballast to be able to lift a load of dirt at full extension. I
put 2 55# lead ingots on the rear.
I followed the plans very closely. I should have used 1/4" hyd hose for
all of the work circuits, instead of the 3/8 I used. Hose routing and
pinching would have been better.
I had some trouble with breaking the ends on the two largest pivot pins...
the one on the boom pivot and the one on the boom/dipper pivot.
Other errors I corrected on the plans as I found them, but if your unit
is almost all welded up, it is moot.
