I bought a NAPA  791-6420 3.5 ton  steel jack about 8 years ago for about $300. It never quite worked right, always acting as if it had lost its pump prime. Seal kits are no longer available for it but I did find that a simple o-ring in the pump was worn. A replacement o-ring, industry size 204, has made a world of difference, but the way the pump is designed, it is just a matter of time before that o-ring wears out. There is too much side play in the pump piston. Another example of China design. Very disappointing. I like my NAPA store since they are locally owned and are excellent with farm and truck related parts but I won’t buy another one of their jacks. Years ago, their American made “Fleet” brand of hydraulic jacks were excellent. Time marches on.

After 16 years of good use my Sears 3 Ton jack is given me problems.


The handle which is used to raise and lower the car also, if rotated ,is used to open and close a valve. through a gear mechanism Unfortunately, the gear mechanism has locked up.


If I remove one of the gears, can can manually close and open the valve by hand, This works OK, but if I have the jack under the car, this involves me going under the car too. Something I don't want to do.


So I'm on the hunt for a new jack. I'd like something light, but I need about 2 tons. I have  Stag.

Any recommendations?
