Well, some people just do not learn... As you remember, I bought a Weaver Utility jack without seeing it from CT (https://www.garagejournal.com/forum/threads/old-weaver-jack-weaver-utility-5000lb-jack.456508/ - still sitting in my garage, one day it will be hopefully fixed)

I found another Weaver Jack in CT. It's a WA 72. Per person listing it this one also was working and not leaking. After 2h 20 minute ride I met the owner (jack posted by the wife - I probably should have dialed a phone number to speak to the husband, but I just used interaction via facebook marketplace). Very nice person. He told me that jack probably leaks and will likely need some job to bring it to a former glory. I decided to just buy it since I already drove for a very long time... In addition since I have absolutely no experience fixing jacks and have no diagram on my Weaver Utility, it will help me figure out what is supposer to be where (if you look at the other thread, you will see that some parts rusted into oblivion. At some point I will probably put jacks side by side and try to figure out which parts are interchangeable (Weaver factory does not have the diagram to my original jack as a lot of documents were lost in the fire in the 50s)

WA 72 jack.
2-3 layers of paint.
The code is _ BAO 242 (Unfortunately I can not see the first mark - I hope that when it gets warm I can carefully use wire brush and find it somewhere under the paint as there is a big spread of when it could have been made: 1 would have been 1937+, 2 would have been 1949 + 3 would have been 1961+ ....)
outside to see how much it moves.
The jack has a lot of grease on it and probably not much rust under grease and dirt.
The ram is not perfect and has a small abrasion on the bottom.

...Got it for $50 (plus around $29 in gas...)

Potential outcomes

1. Wait till it gets warm in MA and try to fix it (I wonder if the ram will need replacement or not)
2. Use some parts when I eventually get to my Weaver Utility Jack (assuming hydraulic unit of it can be saved (? and a new ram sourced/made)


Please leave comments and opinions. If you have a W72 jack, please post the pictures with the codes and ageWA72_4.JPGWA72_1.JPGWA72_3.JPGWA72_5.JPGWA72_6.JPGWA72_7.JPGWA72_7A.JPG

Few more pictures: if you look at the plate next to the handle, it looks pretty simple - I wonder if I have a jack which was built later (not sure it this and may be the way the wheels are attached might help me ballpark the age)

... And I could also get couple of pictures of the jack from the bottom with the pedal up (to look at the spring length) and from the top (to see where the metal connector which sticks out should normally be positioned), it would be fantastic!

Can't help you with your questions, but I have the same (or similar) jack patiently waiting for me to get to it. Mine leaks out on the floor, so I know it needs something. I'd like to do a full mechanical and cosmetic restoration on mine.

Thank you,MushCreek. If you have a chance, please take pictures of the jack from the side, top near the handle and the bottom with the pedal up
We both might need to do some leg work in the future: Casle Equipment no longer provides the list of parts with prices and referred me to the manufacturer.
By the way - if you get a code from the cylinder and call Weaver, they will give you the age of the jack. If you do it, please post it.

About the scuff on the ram, I've seen it discussed here before using some JB weld and smoothing it out with some sand paper. I've never used that method before but if the ram isn't bent it should work pretty well sealing up any oil leakage.

My Weaver "WI-73" (I=Canadian Version? never had that confirmed) is tucked away and I haven't given it any thought in years. Way too big for a residential setting let alone the oil leaking issues it has...

Good luck on your project, Weavers are known for their stupid simple designs that last forever, a little bit of work and she will be good to go for another 50 years...

To my old eyes, you serial number looks like 3AO- 242. I dragged my old jack out, and it's a WA73, which is the four ton model. Mine is 2AD-917, which would be a bit older model, between '49 and '61. Mine has a fancier cast cover with ribs in it. My release handle doesn't have 'WEAVER' on it; just a part number on the underside.

I found rebuild kits various places. Castle tells you how to tell if you have the old-style pump, which requires different parts. I also found a site www.hcrcnow.com that sells kits and has pdf's of the parts diagram and list. Scroll down to the bottom of the page for your jack. I'm going to tear mine down and inspect it prior to buying a $127 rebuild kit. I want to be sure it is rebuildable.

Thank you, MushCreek!
I called the Weaver Factory - may be I should try calling again at some point (they thought it would be #BAO-242) ...
I will look through Lazzar's Floor jack

When you decide to tear down yours - please create a thread (and put a link to it on this thread as well)
