im going to psost here so as not to be typing the same thing over and over.
the pullys, i have no clue what application they are from. i just found them at the yard i work at. i cant find any more the right size in the yard now. i made that one for a tow truck, i need to make one for myself now but as a snorkle. the pullies were oxy torched out in the centers, then welded together with a mig. a water pump style pully was then welded to the to to make the hole smaller for the nuts. washers had to help a bit as well. then the oxy was used again to cut a hole for the drive shaft to be welded on. the sand filter is more a sand trap. it creates a "tornado" and hold the heavier particles down in the bottom. it is the clear and black canister on the left of one of the pictures. i found a better filter box to use off a crystler minivan. i will be using this one when i do mine. as for the sand trap a local tractor store will have one for under 20 dollars. once i actualy do the one for my truck, and it will be a while, i will post a write up on it. i will be forced to use new pullys i think and i might be making a few of them to sell. but i need to many parts before i can start on it for my own rig. and i need to get the drivetrain back in my rig before i start on it as well.
