Your hydraulic system is probably close to mine in that you have a large hydraulic reservoir with filters inside. The fluid is filtered prior to going to the pump and then it goes to the motor and steering.
If the pump had a catastrophic failure it could have sent trash to the steering gear box and fan motor.
I'd suggest draining the hydraulic reservoir and changing the filters. Take the filters apart and look for contamination. If contaminated you may have to pull the steering box and motor and have them rebuilt also.
Here's a parts page showing my reservoir. It has the filter number on it.
