rebntx Posted June 28, 2015 Report Share Posted June 28, 2015 The level of fluid in the reservoir for my hydraulic jacks is very low. My manual does not tell me what kind of fluid to put in the reservoir and nobody I talk to seems to know...do you? Link to comment Share on other sites More sharing options...
Darryl&Rita Posted June 28, 2015 Report Share Posted June 28, 2015 What brand? Different brand, different fluid. What temperatures? Different temps, different fluid.

pjstough Posted June 28, 2015 Report Share Posted June 28, 2015 If you have a HWH system, you can use Dexron automatic transmission fluid. I am not sure what other manufacturers recommend. 2005 Winnebago Voyage 38J Link to comment Share on other sites More sharing options...
Big Greg Posted June 28, 2015 Report Share Posted June 28, 2015 Not sure which system you have but Quadra's Big Foot leveling systems use this, from their website: "Our Pumps require ATF (Dexron III) do NOT use hydraulic fluid in our systems."

docj Posted June 28, 2015 Report Share Posted June 28, 2015 RVA jacks use Dexron III also. But for RVA jacks put one jack down ~6 inches when filling the reservoir.

Kirk W Posted June 30, 2015 Report Share Posted June 30, 2015 Both brands of jacks that I've used called for Dexron III. I can't recall ever seeing one that used hydraulic fluid.

Ray,IN Posted June 30, 2015 Report Share Posted June 30, 2015 Quote from the HWH FAQ page: "The use of HWH Specialty Hydraulic Oil is recommended but Dexron or multipurpose transmission fluids can be used if necessary. DO NOT use hydraulic jack oil, brake fluid, or power steering fluid." 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis. USA IN 1SG retired;Good Sam Life member,FMCA ."

Kirk W Posted June 30, 2015 Report Share Posted June 30, 2015 My manual does not tell me what kind of fluid to put in the reservoir and nobody I talk to seems to know...do you? Wondering what make your jacks are, and do you mean the manual for the motorhome or the one for the jacks that is published by the jack manufacturer? If you need a copy of the one from the manufacturer, many of the companies have those available online. Good travelin !...............KirkFull-time 11+ years......

57becky Posted July 2, 2015 Report Share Posted July 2, 2015 The Lippert products all call for ATF, but specifically say to not use Type F, as it will cause seal failure. One thing to understand is, ATF is hydraulic fluid, it just has a dye in it and special additives to help it work in transmissions. Link to comment Share on other sites More sharing options...
mscans Posted July 2, 2015 Report Share Posted July 2, 2015 The storage tank sometimes has that info cast or labeled on it. As others said, find the manufacturer and look up on the net. Failing ALL that post a picture of the leg or pump unit here and someone will recognize it I'm sure. Happy Trails, Florida Mike EXPERTS AREN'T!!
