Got an infrared heat gun ??  sounds like one of the problems I had,, blown "O" ring under the cab on right hand side.  priority valve I beleive it was.

Get the oil up to operating temp and check all the hydraulic system you can get the gun on.. 

Oil should not vary more than 10-15 degrees till it's returned to the rearend.

The priority valve working property, will always default to steering and brakes over any other hydraulic draw.
