Well friends seems like the bad luck has struck. Close to Lincoln Nebraska we lost the splines on the hydraulic pump. This pump operates the power steering and the cooling fan. We ended up spending 33 hours at a wayside taking the front cover off of the big Cat and replacing a gear. No pump or parts to fix the correct pump so we did the next best thing. Adapt something to turn the fan. We found some really helpful guys at the Surplus Center in Lincoln Nebraska who found us a pump to adapt. Seems like it was good luck having it happen so close to Lincoln, Nebraska!
