My D6 has a hydraulic pump mounted in front of the radiator for the blade. The pump is driven by the crank shaft pulley. I need to disconnect the pump drive shaft so I can put the new fan belt on the crank pulley. Do I need to drop the belly pan to get access to the pump drive shaft. I have already removed the water pump because the adjustable pulley was frozen and it was easier to work on it with it off the dozer.
I would think it would be better to and grill too
