Hello all. Well i have made the decision to do an inframe overhaul on my Cat 426 Backhoe and have already run into a major stoppage. I started pulling off all the items i could get to before removing the head. The water pump is mounted on a base/housing that attaches to the head. There are 4 bolts that holds that part on. So you would think that one could just remove those 4 bolts and the head would be free to just remove it? Well no BC the water pump is mounted on that housing and there is one bolt INSIDE that housing that also holds the housing to the head and only way to get to it is remove the WP.
So had to take off the fan guard and thought i could unbolt the water pump from the housing and just lift the pump and fan out? Turns out that the fan will not go forward enough to let the pump impeller clear the housing, so now i can not get that last bolt out. It looks like there is no way to get the fan/pump combo out of the way without pulling the radiator?
So if anyone has ever done this and has a solution i would greatly appreciate any help on it.
Oh yes, i did think of that service manual thing but would have to float a loan to buy it. LOL
