Is this Walker floor jack worth rebuilding?

[C-Rad]

I recently bought this Walker jack and I’m wondering how difficult/expensive you all think it might be to restore.
I think it’s a Walker 781 “shorty”, but let me know if I’m wrong. The tag is inconclusive.



It looks like it started life as a model 781 (faintly stamped) and was stamping over with 767 and/or 764
The handle/yoke looks like it came from a larger model and was modified to fit


It has some other issues:
Cracked front iron wheels



Can I find replacements, or repair these?

The pins/axles for the rear wheels are welded on, and I might need to take them off to get the wheels to turn (rusty)


It’s rusty on the bottom with dry mud as if it sat in wet dirt for years. Is it a problem?






Thanks for any feedback

I think you will find that one a struggle due to the cracked wheels and rust on the pump shafts, and I am usually a refurb addict.

How badly do you want to restore it? It would need new parts, but since you already own it you might look into getting a used pump that would fit it. And a pair of new wheels. I'd go for it if I had the time. It is a cool looking jack.

Depends on how bad you want it.

I'd scrap it, definitely too far gone and since it looks quite abused it isn't worth anything to me.

Does the rust on the exposed part of the shaft(s) mean that the shaft is shot? Are those now rusty shafts supposed to be mirror smooth and seal against o-rings?

Maybe - what you need to do, is expose the part of those shafts that we can't see; if they're as rusted as the parts we can see, that's an issue. If the cylinders in which they reside are rusty and pitted, it's pretty much end of game, unless you're really up for a challenge and have lots of spare time on your hands.

Usually yes, unless you really want to spend time polishing the shaft, and possibly the cylinder walls, and then finding oversized seals etc to make up for how much you polished off. Tried it once a long time ago, won't do it again on hydraulics or pneumatics.

I just needed a second jack (preferably vintage) to help me restore old cars I don’t have time for. This jack I s probably too much time and money for me to restore. It still has the removable cast iron cover that says “Walker”, which is often missing, so maybe I can sell that to someone with a restored/restorable Shortie who needs it.
Thanks for the replies guys.
