Hello ChiScouter, Welcome to the forum.These jacks were at nearly every service station in the 'old days'. Today they sit in the corner at most shops who still own them, as they are too tall to get under most modern iron.

Low oil will keep the jack from going the whole way up, air at the pump,will make the lift small with each handle pull. I have seen many working jacks of this type change hand for under $200.00.

Most jack repair shops get over $100 to repair one. If you work on some old cars from the 50's back, it could come in handy as some of these cars can be 2 tons or more.

Hope this helps. I have a 10K pound walker circa 1940 and i've been using it for over 30 years. Powergold 12. Walker is now under the Viking name which i believe is somekind of swedish or danish co.

They do not supply parts for the older walker that i know of. Be sure that the filler plug on top of the cylinder nearest the handle has a vent hole in it. I replaced the seals in mine about 6 years ago because it got leaking oil so bad.

The kit was given to me about 20 years ago and i think it was about $45 at that time. This is the finest floor jack i have ever used and i have at least 4 other smaller jacks (no not those china-rican made things that u can hold under your arm either). I always grab this walker first tho despite its enormous size and weight.

I've had NO trouble at all with it being too high to go under any cars modern or otherwise. NOTHING will lift as high as this model i have. It was originaly made for trucks. I wouldn't trade it for 10 of the most expensive modern jack there is. Filling with oil is a bit slow tho.

Use ONLY jack oil. Question Writer 4 Crack more. NOT engine oil nor trans oil nor anything else. Fill it with an oil squirt can filled with JACK oil. Again, filling is slow and kind of tedious. These big massive jacks are great for lifting a car and swinging it around the garage or manuevering a cor into tight spaces. Removing transmissions and i even lifted a jeep one time with it all 4 wheels at the same time from the centre. A marvelous piece of equipment to be very proud of owning.

Keep me posted on your findings of parts availability. I would like a new cylinder and Ram for mine.
