Some 3930 questions

So just tinkering around I found some things that I'll be addressing. First one is i noticed I could hear what sounded like the fan blade hitting the shroud every so often, upon investigation it's quite obvious the bearing in the water pump is about gone and there is a lot of play in the shaft, so I'll be ordering a complete pump since I dunno how long it's been like this and there's probably damage elsewhere inside the pump. Now, I've looked at all the diagrams NH has for the water pump related parts, but this tractor has two extra lines, one comes directly off the water pump cab tractor heater port and runs through to behind the oil filter, the other comes out of the rear of the block and goes to the same place. What is the deal with this? Can't find anything on it, guessing it is additional cooling or maybe some type of oil cooling due to placement. The other question I have is i noticed the right side front axle control arm is loose, tried to tighten it it already had some type of shim in it and of course the threads were already stripped on the bolt itself, gonna try again with a new bolt. The control arm is a square hole not a round that seems to be readily available. If it's wallowed out to where it needs to be replaced is there anywhere these are available?

on the steering control clamp may not be the best solution but i have that problem also. the way i fixed it i got a new bolt and tightened it as much as i thought i could without stripping it. ground the paint off the top of it and used some nickle rods and put a good weld on it. usually lasts 3-4 years and i grind it off when the weld breaks and do it again.
