Tree Farmer C5D serpentine belt replace

[mritchie]

Hello all, does anyone know the easiest way to replace the belt on the tree farmer c5d with a duetz?  There is a u joint that goes off the front of the crank.  Is it easier to unbolt the hydraulic pump and hoses, or is there a way to get that u joint off the crank pulley that is easier?  It is hard to see in there.  I don't see a set screw for the u joints to slide off a shaft either.
