Trolley jack Repair ( Piston ) ( Floor jack 2.5 Ton )

The smaller of the two pistons snapped on my 2.5t Trolley jack piston. I dismantle and replace the piston.

Oddly I have same jack and the same piston is giving a problem but mine is sticking and jack stops working till you use something to make it pop up again so Thank you for video , I got my jack at Harbor freight and they have parts replacement for it but it started month after I bought it must be design flaw.

Left is low pressure, Right is high pressure. My left piston is sticky and can see bubbles with soap water escaping. I need to repair it today, Sealey sent seals for free. I hope that solves it. Thanks for video.

Very useful video, I have one very similar in style but made of heavy alluminium. nt smaller pidton i jammed right in si I suspect its bent. I can now see how I can remove it.

Is the small piston filled with oil inside? Or should it be empty cause On the other one it got oil.

I have a Pittsburgh 3 ton jack that won’t lift anymore. Where do I find the replacement pistons?

[@fixitfallows]

These are the ones I used, you'll need to work out if they fit your jack : a.aliexpress.com/_EzT9x9L

Am I right in saying it's a generic jack , mine is leaking from where the piston screws into the body on both pistons , I just can't shift them their solid , any idea how to get them out , thanks in advance bri

[@fixitfallows]

Yes, I think these are generic and sold under many different brand names. Mine were pretty tight too. Have you tried creating a bit of an impact wrench scenario using a club hammer against your spanner ?

[@brianfirth9611]

@fixitfallows thanks for the reply I appreciate it , ill give that a go thanks

I’m struggling to find the piston ,please post the link in the comments 👍

Remind me, are they not just "o" rings ? If so, measure your existing one with a pair of Vernier calipers ( "o" rings are sold as internal diameter x cross sectional width. Or vice versa). Numerous places online to buy o rings super cheaply.

So this fix was carried out in October 2022. As you can see today I posted a video about changing the brake pads on an Audi A4 in which this jack features. The Chinese replacement parts are still working fine one year later. Here in Europe most things are made in China, even if the brand is European.
