How to Repair Leaky Floor Trolley Hydraulic Jack Duralast Fix

[@eLiV8t]

In case you missed the size, it was at 4:55 P8 7.8 × 1.9mm

[@nicam49]

Thanks that's great! Looks just like all of the budget jacks sold in the UK irrespective of the name on the jack.

Because of your video I learnt something new today 🇹🇹

Thanks mate, just the video I was looking for. Mine was leaking at the very spot.

[@Patriot-bn9om]

Thanks for the video. I was about to go by a new floor jack because mine failed. Lucky for me, I found your video and was able to repair my jack with the $4.99 Harbor Freight O-ring kit (Item # 67609). Saved me well over $100.

[@raymondjiii]

Nice. But can you tell how to bleed the system of any air and where to fill since a lot of oil (on mine) has leaked out. Thanks.

[@kerryclark1926]

To bleed this jack, 1. open the valve (on this particular jack), 2. remove the fill plug, 3. put pressure on the saddle (the arm that raises up), 4. use the handle and operate the mechanism up and down several times, 5. fill the reservoir with oil 6. replace fill plug. 7. test to make sure it raises and lowers and holds weight without sagging.

[@OLong-fv8vq]

Nice Job. Very helpful; quality video presentation- good camera work, narration, and editing.

[@rickwilson8352]

Aha! So that's how to remove the piston. I was trying to make it much more difficult. Many thanks!

[@dwinsemius]

@Rick Wilson: kzbin.info/www/bejne/Z4qupZWufMiGn5o This guy demonstrates filling and bleeding a Duralast jack.

[@zio2485]

Can you tell me what is the makers name on the o-ring kit and where you got them? No auto parts around me have P type o-rings.

[@glencoe6305]

So, you just compare the old O ring with the New O ring,and that's how you know which size to put on there ? Also, where did you order the O rings from ? Thanks a lot. My was leaking. First the wire that was connected to the Pin and to the pump broke. I bought some wire and hooked it up,then the Pin wouldn't stay all the way down, and fluid started leaking. The Jack wouldn't stay up either.

[@carreranlehu]

Thanks Man. I will repair my trolley jack this weekend. Mine has the problem that get air, thus it not stand under load.

[@johnjkizer6399]

I know it’s a older reply but if your Jack does not lift and no oil leaks out then you just need to bleed the air out, with most floor jacks it’s either leaking oil or needs bleeding

[@BubblesTheCat1]

​@@johnjkizer6399How do I bleed the air out?

[@wonderwalls3565]

I have teh exact same problem but my O ring is not really O ring but somethign made of clear material and quite think in width. any idea from where i can get that?

[@vinkorosandic2901]

Oil filling?

[@pgbrandon]

There is a rubber cap on top of the cylinder that you have to remove very carefully. I used a KZbin video to do it today and it is back working!

[@aaron4376]

Lol he means hydronic fluid i am guessing, or shoot, oil may work, but not as good.

[@miguelalzatepena1624]

Thanks. I will do this. Wich oil should i use to refill?

[@BrendonHoppy]

How do you refill that Jack?

[@kghwanadoo]

Hi on the top of the cylinder is a rubber bung, remove that and with the cylinder down fill to the top with Jack oil. Job done!

Thanks so much for the video! Is very informative and answer quite a few questions but I am still puzzled by my jack leaking oil from underneath. I did not think it could leak from under it but only from the obvious places. Guess gotta keep looking for the source of the leak...

Have the same jack, didnt work also replaced gasket by tensioner and filled with jack oil. Threw it out

Great video and good info. Thanks.

[@bobomomo3764]

Anyone know what are the sizes for the other o rings found in this jack? 💛

[@SGobuck]

If you have calipers, you can measure the diameter and thickness..or if you buy a set like he did, you can match them up to the chart and the corresponding o ring compartment.

What size is of o ring

[@erich5686]

Was that a Viton or Nitrile o-ring ?

[@Weezulguy]

PENISRING

[@mikem6176]

This looks identical to a jack I just found discarded. That one has no cover plate, so I there’s no make or model#. Needs a new cylinder assembly, as an O ring replacement failed to fix the leak. So for about $15, I’ll have a new jack.

[@Your-Mom__]

These go for $20 new

[@mikem6176]

@@Your-Mom__ Maybe, but there’s no challenge in that.

[@Sixnofrets]

It doesn't need to refill the missing fluid?

[@JorgeMartinez-dp3im]

Anybody know what the equivalent washer size would be in the US?

[@duanecjohnson]

7.8mm X 1.9mm = 0.307" X 0.075" However, you will mot have any difficulty finding metric O-rings in the US. redrok

[@dwinsemius]

The smaller Duralast jacks do not have an O-ring. And if you fill the reservoir to the top you cannot get the plastic plug back in until you empty some of the (incompressible) fluid.

[@johnjkizer6399]

All jacks have o ring seals, 100% guaranteed, your model made be made different

[@jessicamoore2955]

Trying to find out where does oil in at ?Because my back will not go up.

[@makestuffwork9205]

On the big cylinder itself there is a bump the same colour as the Jack. This is actually a rubber bung just over painted. You should be able to pop it out and fill there. It's quite a tight fit to get it back in. I had to twist it in, even though it's just a rubber bung. Replace the release screw o ring whilst you are there. Mine leaked from both. As someone else mentioned, this is the same Jack as Hilka sell in the UK at Screwfix as well as other manufacturers.

[@BrendonHoppy]

[@alexanderwebb680]

Did you try bleeding the air from the jack and replacing the oil?

[@bobjackson4720]

@@alexanderwebb680 Many times but it didn't help I think the seals were gone

[@alexanderwebb680]

Sorry to hear that. I'm not sure what to do about a blown out main piston seal. Seems like you can find replacements for more expensive jacks but with the smaller less expensive ones it's expected to buy a newer (better) one. I'm hoping to get mine working tomorrow, got leaks at the bleeder screw and pump piston. Going to replace both o rings, fill with fluid, bleed air and hope that works. If not there's a nice jack at home depot with my name on it.

[@salamabod1975]

@@alexanderwebb680 how can you bleed the oil or replace it please?

[@alexanderwebb680]

@@salamabod1975 To bleed the air out of the system you have to unscrew the valve that you normally unscrew in order to lower your jack. You don't want to remove it entirely though. Once the valve is unscrewed enough that the jack will not lift when you moving the handle up and down, you're going to want to continue moving your handle all the way up and down about 10 or 12 times. Then fully re-tighten the release valve, and jack it all the way up to check if it worked. To replace the oil, you have to remove the rubber plug, and turn the jack upside down over a bucket so the hydraulic fluid can leak out of the drain plug hole. Then you simply fill the reservoir back up with hydraulic jack fluid from the hardware store and bleed air from the system like I described. But you must be careful when bleeding air from the system after replacing the oil, because the rubber plug can pop out while you are attempting to move the handle up and down. This can spray hydraulic jack fluid into your eyes. It has happened to me, it makes your vision blurry and can injure your eyes. I had to flush my eyes with water for a long time before I could see clearly again.

REALLY SAFTY SEAL points up, or presure safty, and yes there is a cover plate. But i tryed to wing a repair. I blew the seal and got a hydronic punch in the head. Luckily the top safty seal went when i stepped on it; only my foot in weight. WTF the safety valve points straight up, really. I am ok lol, just have dumb moments 😆 🤣

Mine does not have a seal, cheap crap.

[@adamantiumrage]

This thing sucks. It advertises on the box it can lift an SUV. It can, but not high enough to even get the damn tires off the ground! Absolute crap 🙄

You have to use wood block with the jack to bump up the height

[@MagnusonX]

@ ….. or buy a jack that lifts higher. Some people that all jacks work for all the same applications, which absolutely not true.

[@MagnusonX]

@ Be careful using a wood block. Doing so may not allow you enough clearance space needed to fit the jack with the block underneath.
