  1. Installed a400 horsepower 855 in a 4586 it ran for years without any problems. The hardest  part was the hydraulic system  had to get a gear reduction pump  because engine  auxiliary  drive wasn't  heavy enough  to drive pump. Keep in mind that the differential and final drives are 1466and 966 parts. Added 11 inches in frame if I  remember right  used low mount turbo manifold. If you let the air out of front tires it makes it a lot easier to work on.

  2. Does  the loader work right if you put the tractor valve on demand? Hydraulic system on a 300 is an open center so oil will go to less load . To get the system to work with it teed like it is plumbed you would need a flow divider  in the system. The easiest  way to plumb the loader valve is hook it up like a remote rear cylinder  and wire the valve on when you use the loader.
