    When the speaker mentions new oil is too dirty for the hydraulic system it reminded me of our experience. Years ago Deere required us to get a super caddy with a digital iso cleanliness readout. When we replace a component with either a new one or reman we have to bring our iso numbers down to a certain level for Deere to warrant the parts. Back when this started we decided to have our bulk tanks tested and they all failed the iso cleanliness. We had questioned Deere and even back then they new that new oil was too dirty. That was why we now have the filtration systems we have now for cleaning the hydraulic system after a repair. Unfortunately we never installed any filtration on our bulk tanks to filter the oil upon installation.

    Actually oil polishing system would be a good idea for the long term storage tanks, not only for removing mechanical contamination but also for biologicals, and including at least one desiccant filter is good too, we all know that doesn’t matter how much you try to keep moisture away it is present in the oil anyway! And with hydraulic oil anti emulsification additives it’s not always apparent!

    Same experience here. New oil supplied by oil companies to bulk tanks that would not meet the required maximum ISO 16/13 Cleanliness Code.
    When fronted up about it, the oil company responded - "We can supply you oil at any ISO Code you want. It's just going to cost you extra..."

    Last job we had recirculating filters on all our bulk tanks and basically kidney-looped new oil long before it went anywhere near the machinery. IIRC our 10W hydraulic oil out of the dispensing nozzle was something like ISO 13/10 or 12/9.

    thanks for the video TVA,been pouring buckets of hitachi oil for years straight into the the hydraulic holding tank,the head deere mechanic said thats how he does it, so been doing the same. but what i cannot figure out is i have a few equipment owner friends that are pouring in tractor 303 from tractor supply. they just say its better then nothing. you would think that would wear a system out quickly.

    now on the hoses, during the hose cutting,end crimping procedure what is the best way to clean out the hoses after they are built?

    thanks Nige will have to look into that, most hose guys just beat the hose against something and call it good. did not think about the heated up debris sticking inside the hose.
