FlyingDude Posted October 17, 2022 Report Share Posted October 17, 2022 Hello all, I wanted to ask for pireps on harbor freight long-ram bottle jacks. I thought of using them to replace the jacks in the aircraft jacks that were handed down by my friend who owns a Debonair. I'll re-use the base and support structure. Unfortunately they started creeping down, like 1" over 24 hrs. That's not too bad if you're doing a gear swing or replacing tires, but unacceptable for me. Yes yes, harbor freight is chinese stuff, but honestly; what isn't made-in-china nowadays? Do you have any pireps on those jacks? Do they work fine? Do they creep down? Thanks.

DonMuncy Posted October 17, 2022 Report Share Posted October 17, 2022 I agree you want the best jacks available, but even more, you want a "collar-clamp" on the ram to be able to fix it in place so it doesn't creep down. 2 Quote Link to comment Share on other sites More sharing options...
EricJ Posted October 17, 2022 Report Share Posted October 17, 2022 The jacks you have are probably rebuildable. Usually it's just replacing some o-rings inside to rehab them. 1 1 Quote Link to comment Share on other sites More sharing options...

Try pumping until the rams are fully extended and then pump an additional 10 to 20 times with the ram against the stop. Jacks that sit dormant for months on end often leak down. I do not know why driving fluid through them with the ram fully extended sometimes solves the issue but it does. 1 Quote Link to comment Share on other sites More sharing options...
FlyingDude Posted October 17, 2022 Report Share Posted October 17, 2022 I do have clamps. They dont creep down with clamps. But I don't want to rely on the clamps... Thanks for the tips... Quote Link to comment Share on other sites More sharing options...
kerry Posted October 17, 2022 Report Share Posted October 17, 2022 After you jack your plane up then place 32'' saw horses under the main spar 24'' outboard of the mains. 2 Quote Link to comment Share on other sites More sharing options...
MikeOH Posted October 19, 2022 Report Share Posted October 19, 2022 I am reminded of a quote from my high-school auto shop teacher, "Do you want to trust your life to a $0.03 Chinese O-ring?". I RELY on jack-stands and clamps, NEVER the seals in a jack. 1 Quote Link to comment Share on other sites More sharing options...
