Long ago I won a lot of used tools at an auction. Among them there was a small two ton jack.<\/p>\n\n\n\n

Overall it was in fair condition but the lever was really hard to move, so I left it with other low priority things to repair.<\/p>\n\n\n\n

Upon a closer look the smaller piston was bent. I chucked it into a vise and tried to loose the nuts but they were firmly stuck.<\/p>\n\n\n\n

I cleaned the base with a rag and wire brush and then welded it to a piece of iron channel. I love 6010 rods. I also learned that whatever was used as hydraulic oil catches fire with ease.<\/p>\n\n\n\n

Laying on the floor with one foot on it I used a big wrench and a hammer, this time succeeding in getting it apart.<\/p>\n\n\n\n

It doesn’t seem like much but this small curvature made it almost impossible to pump:<\/p>\n\n\n\n

I decided against straightening because with the tools I have at hand it would be very certain that I’ll scratch the good part of it and thus completely ruining the jack. So I cut the bent parts with an angle grinder.<\/p>\n\n\n\n

Just by chance the parts that were badly out of shape are almost the same length as some ground rods I have from a textile machine.<\/p>\n\n\n\n

The plan goes like this: drill and tap the remains of the original piston, make the rod hole bigger and use a long bolt to hold them in place.<\/p>\n\n\n\n
