Where are you located, type of weather, if you have an owners book it should tell what weight, I changed mine last fall, I got a good buy on some AW 46 but I still needed 35 gallons so I got that in AW 30 so I could thin it a little my pump holds 85 gallons, change your filter to , I change my filter every 100 hrs. |

If your hydraulic oil is milky in color it is likely water in the oil. |

Water will separate from oil. Let it set and then drain bottom of tank. |

I use a ISO 32 weight, or viscosity in my pump truck. I don't think the brand matters that much as long as its clean. You might want to drain your water box before putting your pump away. Also drain a 1/2 cup of oil out of your tank bottom drain every day it gets rid of the water and gunk. |

You might want to check the hyd. packing on the diff. cylinders if your oil is milky. I use a ISO 46 in the summer and change over to a ISO 32 for the winter. |

As said,milky oil means water mixed with oil.A faulty fill cap,vent,chevron seals on diff cylinders,bushing at bottom diff cylinder. Lets say the chevrons are bad,it can allow grit from water box to enter the hyd system,should the filter plug it goes into bypass.This allows grit to reach hyd pumps (yuk). Drain water/moisture daily,every year drain and clean tank,refill with new oil.Another thought would be a filter cart at each scheduled service.Just some thoughts. A free call |

I wonder which oil he's talking about my wet box I use old HDY oil and change it about once a month,cause it get milky white just from pumping water gets by the poly paks from pumping, but if you are talking about your main HDY tank any where from 50 gallons and up if its getting water in it like someone esle said check your fill cap, water will get the the bottom so just drain some off. |

have a 2000 tkb 30 that had a driver seal in backwards, first fix did not work. second time did but later there is some leakage into the box. otherwize i have had no condisation problems. would check if the driver are syncronized right. if there is a problem changing the oil will not make it go away. |

Most likley the water is coming in from the waterbox. As hyd oil heats up, it expands or gets 'fat'. While you are pumping, this is fine. But when you are done pumping, the fat oil starts shrinking. If you have not drained the waterbox, the shrinking of the oil can create a vacuum and suck some the water into the system. 9 out of 10 times, this is the problem. And it only gets worse from here due to cement, flyash, silica fume, etc, entering the hyd system. Remember, drain your water box within 30 minutes after claen out. |
