I bought this ram to replace an old jack with leaky seals in my engine hoist. The old jack had issues pumping up, but held its position indefinitely. I have had to have multiple Vevor rams as replacements, both with the same failure mode. The first new Vevor jack I got pumped up fine, but would quickly loose its pressure/position over a few hours time. Vevor sent me a replacement second ram, after a bit of back and forth with their technical support team. Unfortunately, the second ram has the exact same failure mode. Not matter how hard I tighten the hydraulic bleed valve, these rams will lose their position over just a relatively short period of time. It works okay to pick up an engine in the hoist, but I do not trust it to maintain that position for more then a few minutes, it will drop slowly with no load, I would not trust it unsupervised with a load. I've attempted to talk to a real person in the technical team, without success. I would like to know how to fix this as I have little confidence a third unit would be any different.

ce vérin fonctionne mais ne tient pas la charge dans le temps: il s'affaisse progressivement en quelques jours

Bonjour Suite à notre commande de 2 vérins que nous avons reçu et installés Nous avons un problème sur 1 vérin qui fuit de l'huile au niveau du joint Et aussi un problème de clapet sur la pompe double piston qui devrait monté 2 fois quand on pompe Cela ne fonctionne pas ? L'autre marche très bien ! Merci de faire le nécessaire pour nous envoyer un nouveau vérin pour le remplacement de celui ci et que je puisse vous renvoyé celui qui a le problème Je reste à votre disposition Christian Plantegenest Ste PODIOCOM Tel +33 607768097 Cordialement

I bought 5 of these, and they worked great the first time. 6 months later, I go to use them again, only to find that 3 of the 5 had lost all of the oil, 1 lost half of the oil, and only 1 was still full. These are big jacks, and it takes a lot of time and oil to fill them back up. I feel like I just wasted $350 on these 5 jacks. I would definitely not recommend these.

Failed under the load. Communicating with support for refund

we purchased it to use on an existing engine hoist. The first time I used it It only pumped when the handle is going down. Since it is a double pump it should pump on the up and down stroke. With it only working 1 way it is extremely slow to raise anything. I contacted the website and have gotten no response as of yet .

received with all hydraulic fluid leaking, no fluid inside, all fluid was around the shiping box

Came without enough oil, wouldn’t extend. Had to add more than 2 pints of oil and bleed it to get it working. Not sure if it leaked out in shipping or what. Gotta say the price was really good and the duel piston is nice.

This seems good so far. It needed half a litre of oil for it to work properly though.
