| Our IH 4366 has recently developed an issue with the hydraulics. After it sits overnight you have to turn the steering wheel back and forth for about a minute to get any steering, almost like its losing its prime. The remotes seem to work fine and clutch is fine but steering is an issue, also has a more noticeable whine to it until it gets going. What would cause it to lose its prime, no noticeable leaks anywhere and not losing fluid? Any thoughts? |

Northeast Louisiana | Had this before, pump wearing out. Had this happen twice. new pump and no more problems.
When using during day, it was fine, but sit overnite, it loose prime. It just got aggravating to me. |

| Never been into hydraulics on this tractor, is it just one main pump or is there a seperate steering pump like in the other IH's? |

 West Union, Illinois | It's been a long time since we had one of those around, but I believe they just have one hydraulic pump. As I recall it is fairly simple as far as something like this goes. I remember changing out the spyder (#11) on a 4386 at the end of a field one time.
