Not sure if this will help but I had oil leaks on my Hydraulic Fan Motor on a 06 Monterey. I ended up pulling it apart and found matching o-rings and an Ace hardware store and Harbor Freight. Rebuilt it for less than $40. The first time I ran the rig, it overheated, fortunately I had taken a picture of the adjusting screw, returned it to that position and it ran great since.
