ChiScouter Posted February 26, 2005 Share Posted February 26, 2005 I just aquired a old Walker mod 770 Series B 5000 lb capacity hydraulic floor jack. It is about 4 feet long and has about a 4 ft handle. Everything on it seems to work except one of the casters doesn't spin. It does seem to lift, but acts as though it is low on oil. I would much appreciate a rough idea on its age, value, and where to find more information on it Link to comment Share on other sites More sharing options...
KRK Sr. Posted February 27, 2005 Share Posted February 27, 2005 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.

Bhigdog Posted February 27, 2005 Share Posted February 27, 2005 I bought my model 884 in a scrapyard for the cost of it's weight ($10 ). My local jack repair shop ( yellow pages ) sold me a rebuild kit for $45 and xeroxed the exploded views and parts list for free. Pretty easy rebuild and it works like a champ. You will have to make some special wrenchs for the large packing nuts but no big deal. Google search for "walker jacks" says EMail wmogrady@iserv.net for parts and paper work. Good luck..bob Link to comment Share on other sites More sharing options...
nearchoclatetown Posted February 28, 2005 Share Posted February 28, 2005 ChiScouter, I've found info is easy to get from the manufacture on equipment. I think Walker is still in business under their own name. I was told manufactures HAVE to give manuals because you could be hurt not knowing how to operate it. I've gotten several parts and service manuals for older equipment for the price of copying. The trouble is finding who owns the Co. now, sometimes it takes many phone calls. 1 Link to comment Share on other sites More sharing options...
rwoods Posted February 28, 2005 Share Posted February 28, 2005 How rare is a Walker mechanical floor jack? I have a nice working model,it must be out of the 1920s or older.the only thing wrong is the grip on the handle is missing and I dont know what to replace it with.

nearchoclatetown Posted February 28, 2005 Share Posted February 28, 2005 McMaster-Carr has grips, like bicycle grips, of different sizes. Link to comment Share on other sites More sharing options...
rwoods Posted March 1, 2005 Share Posted March 1, 2005 This jack has a flat bar handle about 3\8 thick and 1,3\4 inch wide and the handle was rivited on each side,may have been hard rubber or wood or unkown material. Link to comment Share on other sites More sharing options...
Guest imported_PackardV8 Posted March 1, 2005 Share Posted March 1, 2005 I have a 10K pound walker circa 1940 and i've been using it for over 30 years.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. 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.

Guest imported_PackardV8 Posted March 1, 2005 Share Posted March 1, 2005 ChiScouter. Hmmmmmmmmm. do u have Indian motorcycles??? Link to comment Share on other sites More sharing options...
ChiScouter Posted March 16, 2005 Author Share Posted March 16, 2005 No Indians, IH ScoutsI got a few links that didn't pan out, but I just ordered a parts breakdown from Hydraulic Jack Inc in New York. They don't have a web presence, but their # is 845 626 2510. I just requested a parts breakdown, but he said he still has a kit for my Jack. I guess the Mod770 series B wasn't very popular, They started production in 1941, I didn't find out how long they were made. Link to comment Share on other sites More sharing options...

TerraNova Posted May 2, 2019 Share Posted May 2, 2019 Hello All, I have a Walker hydraulic bottle jack, series A, model 944. It's rated for ten tons. I can't seem to find any information on this model at all, no mention of it on any site. I'm just trying to discover how old it is mostly. It has been in the family for over 60 years.
