Walker 784 "Big Boy" front wheel removal?

[blunosr]

Hi, I'm just now starting on the Walker 784 floor jack that I got from a junk yard a few years ago. Is there a trick to removing the front wheels? The parts diagram indicates "flat pins", does that mean a cotter pin?

I have looked at a bunch of the old threads on here, but folks were using Photobucket, and most of the photos are no longer available.

Thanks for any advice,

Troy

The front wheels have a dust/bearing cover that needs to come off, once it's off you can remove the flat pin, which will allow you to pull the wheel/needle bearings.

I got the front wheels off. There was a fair amount of play in them but the shaft doesn't seem worn, and the bearing races look ok too. I'm wondering if the play is by design?

The main ram is scored, and it appears that a previous owner used sand paper (by hand) on it at some point in the past. I'm wondering if I can put it on a lathe and sand/polish, or hone it? Would the tolerance of the cylinder/ram still be ok? Should I send it out to be chromed?

It seems that there are three leather cups (main ram, speed ram, and power ram). Can I still buy these? Can I just make them?

Thanks,
I just can't figure out how to post photos... I do know how to do it on other forums, but it doesn't seem to take here, so I included links.

Yes, you can try to smooth out those scratches in a lathe with some very fine abrasive paper. That part's not responsible for the seal to the cylinder walls. Some people have been known to use JB weld to fill in scratches on that shaft. If the scratches are more than superficial, don't try to sand them out, you'll end up removing too much material.

So, I've made some progress...

Here are a couple videos of the disassembly, and the rebuild of the hydraulic unit.

Any suggestions on filling this jack? I'm considering taking the top tank nut off and filling that way. I'm not sure how full to make it. Any advice would be most welcome!

Or, should I lay it down and fill through the filler port on top of the tank?

It's totally empty right now.

Thanks for any advice,

I re-read Hiball's FAQ thread. He's Awesome!

Thanks!
