Tools Craftsman leaky 1.5 ton Hydraulic Floor Jack

[@1947froggy]

Worked great, 2 yrs later still fine. July 2023 still good.

[@chipmeister111]

Excellent video. Just ordered my parts to reseal my 3 1/2 ton craftsman (950145). It only jacks up without a load. I'll post another comment here to let people know my results for anyone else that may come along with the similar problem. You've helped out a lot of people. I hope that HCRCnow took care of you for sending them the business. There's a link to this video on their website. Nice car btw. Thanks again Froggy. 🐸

[@doctorbobdc]

Thank you for this helpful video. I hope you cleaned out the jack before reassembly. After all that work, New oil is in order. A paint filter isn't sufficient to clean up that old oil.

[@1947froggy]

Agree, new oil !

[@markandandreawager7981]

Froggy, you are an absolute lifesaver. I have a 30-year-old Sears floor jack that I have used over and over and over again. I had given up on trying to fix it, and then I saw your post. I'm going to order the kit and replace my seals. My jack has a slow leak when it's jacked up and the car slowly comes down. I hope this fixes it. I've grown very attached to my jack. 😅 THANKS!!

[@1947froggy]

Glad to help, worked a charm for me.

[@juliehanawalt5655]

For 6 years been looking for a seal kit. THANKYOU!!!

[@amydaudier3327]

U can use transmission oil too

[@armyblusky]

Thanks Froggy, I have a similar jack with a leak. I bookmarked this for future reference. Eric

[@anton2409]

Thank you for taking the time to create and share this video, froggy. It's exactly what I hoped to find for fixing the same model, which I also bought decades ago. Having all the parts on hand is helpful, so thank you for pointing out where to get the kit, too!

[@1947froggy]

Welcome!

[@joefenech6839]

Great! Two years ago I disposed of a great 2 ton jack after Looking hi and low for a repair kit ..... now I know where to look. Thanks

[@1947froggy]

Yeah, took a lot of looking to find this. Almost all jacks are worth repair if you can do it, not that hard, except need big sockets & allens. :)

[@anthonysalonek1509]

you will always find things when you don't need them,can't find them when you do need them

[@jimmyhuffman6802]

Oh no, you got to rig it now. Oh boy I'm got to make sure I get the correct kit to begin with. Then I'm going to do a full rebuild on mine. I don't want a half ass rebuild job on such a critical tool.

[@Steve_Smith1776]

Great Video. Thanks Froggy

[@jacobalderton9262]

I received this same jack as a gift in 2006. About 18 months (outside of warranty) it decides to give up. I’ve moved a couple times and It’s been trucked in the corner of 3 different garages. It’s been in and out of the scrap pile a dozen times. This is its last chance. Thanks for the info!!

[@1947froggy]

Good luck!

[@domeniconelli8382]

Thanks Froggy!

[@MrSamBowers]

You only use the screw that's on the reservoir to fill it. The other screws you leave alone.

[@barneyrice8502]

yes you were right that spacer was in there from the factory for a reason which means it has to go back with all of the parts like it came apart

[@oeicraig]

Thank you, wished I would have watched how to install the snap ring, before I shot it off into my backyard. Quick question: Where do the ball bearings go?

[@1947froggy]

Sorry, been too long since I did it, don't recall :)

[@HB-yq8gy]

Thanks, Froggy love your videos. I got a 3-1/2 Sears #50145 but it's not leaking or maybe it is. I thought maybe air inside needed bleeding or both it was low on hydraulic oil. I clean it up & lubed it worked fine for while now it doesn't. I'm gonna order kit this jack because now jacks are expensive.

[@teresaramirez3080]

Did the kit work for you

[@HB-yq8gy]

Yes!

[@americantaxpayer4551]

I have the same jack. Speedlift jack. Maybe 20+/- years old. 1st the speedlift aspect blew out. Then recently the jack started dropping, even noticeable after each pump up. Hopefully this kit will fix it.

[@HB-yq8gy]

@@americantaxpayer4551 Yes it will the hardest part was breaking the piston cylinder housing. I had to take the jack to an auto repair shop with pneumatic air tools with big sockets 2' or more. It cost me $10 buck for them to remove it.

[@LestonDr]

Normally there is a warning sign to not mess with this screw head and a plastic cap covering it. This screw head controls a ball bearing and a spring that regulates the max lifting capacity of the jack.

[@1947froggy]

True & it's probably a calibrated spring, but in a rebuild you can disassemble, just put it back the same.

[@notboblevy9752]

"Glued the wheels so it would glide better", what?????

[@CurvyRoadsAreBetter]

Hi @Froggy I’m guessing the seal replacement worked? I don’t see your comment here I’m the comments sections to confirm it did the job 🙂

[@1947froggy]

yep pinned a comment.

[@terryburke2587]

That doesn't look like a 30-year-old jack. The Craftsman jacks from 30 years ago were made in Tawain and before that they were made in Japan. The one in video is from the 2000's. Probably around 20 years old.

[@mitchshowalter4752]

Bought a seal kit from Lazzar for a Craftsman 3 ton extra high lift jack model 950143. When I opened up the jack fluid reservoir there was a little "tubular" screen in with the fluid. Any ideas what it is or where it goes? I have a picture but not sure how to include it in a comment.

[@1947froggy]

It should be just to keep debris from entering when topping off, not critical. Should just sit at the opening. Might even be just a "push fit"

[@jimcapelli1431]

My Pro lift model # G-2593 3 ton jack raises up fine, but won't hold a load. Do you think it needs a total main cylinder rebuild, or just one of the easier to replace o rings. I already tried adding oil and bleeding it. It does seem to leak fluid out of somewhere, but not on top.

[@1947froggy]

90 % it's an oring.

[@adrian-xy7zt]

Very helpful. Thank you.

[@toyman81]

Is it reversed threads on the 2" Nut?

[@1947froggy]

Not that I recall but inspect & don't cross thread.

Adventures with Doctor Joe 2 ton floor jack rebuild does a great job explaining, not reverse thread if same design.

[@djduncan3214]

Does it matter which way you install that u cup (flat side up or u side up?

[@1947froggy]

Been a while 2018, so not sure which you mean, having said that I would do exactly as I did, it worked to this day nov/2021.

[@anselmwong9973]

Great video, I have the 50239 jack which is similar, would the seal replacement fix an issue where the jack does not lift the car without more than the normal amount of pumps? The fluid level is fine but the jack does not work like it did originally. A couple of pumps to get to the jack point, then several pumps to lift the car. Now it is multiple to get to the jackpoint, then alot to lift the car. Thanks

[@jpcheco]

Sounds like you ned to bleed air out of the system. There is a number of videos in KZbin showing how to do it.

[@Talsadventures-3]

I have the same Jack with the same problem, did you find a solution?

[@theblackarrow]

Hey Froggy, thanks for the video. Unfortunately my jack (model 50190)isn’t supported on that website. I’m looking for the seal for the spring pump. Could you please share where else I could look? I can also email you pictures if it helps. Thank you.

[@1947froggy]

I don't know, just use google or bing. Sorry.

[@theblackarrow]

@@1947froggy thank you ! Will keep trying.

[@jimcapelli1431]

Hi Froggy, you mentioned you replaced 3 main o rings (at 14:40) I know where you took the big blue one off, and I believe the small one was inside the ram. Where did the medium black o ring come off of? Again, referring the 3 shown in the 14:40's...

[@1947froggy]

Jim, wish I could remember, been a while, try video again, sorry. Worked.

[@jimcapelli1431]

Thank you sir for website info

[@1947froggy]

Welcome.

[@allmightyjamestown]

hello thanks for the video. I was wondering, I have the same jack. mine has a rubber seal around the fill screw. does the kit come with a new one? mine is kind of falling apart and leaking from it. thanks for any response.

[@1947froggy]

It's not that important unless you tip the jack (not recommended). You can get a cheap multi size set of o rings for a few bucks & have one to replace it. :)

[@The2pfagan]

Thanks for the video. When putting it back together, did you use a torque wrench? If so, what what ft. lbs. was used?

[@1947froggy]

Good question, no I did not. These fasteners are not like, say, head bolts or lug nuts. There is really not much tension or torque on them trying to take them apart. The hydraulic pressure is held by the orings. So just tighten then up good, hard as you can on the big ones. Thanks!

[@The2pfagan]

@@1947froggy Thanks for answering my question. I thought it was expensive as well, until I realize how well craftsman was put together back in the days (I have the same one which makes it more easy to follow your video). I hope to work on it within a week.

[@1947froggy]

Craftsman branded tools used to be better, this one is almost 30 years old & used a lot, so a small leak (fixable) is ok by me. BTW the kit worked fine, no leak since I posted the video. Better than my Harbor Freight jack, but the HF did not cost 1/2 the price of the Craftsman.

[@metalheadrelic9873]

I have a later 2 ton Craftsman model #50239, has a smaller underscored 9 before that #. Will this repair kit work for that jack as well?

[@1947froggy]

Sorry, I have no way of knowing.

[@metalheadrelic9873]

The PDF of the owners manual below product description shows the exact same model #. I'm gonna take my chances and assume it's the same repair kit. Thanks.

[@1947froggy]

@@metalheadrelic9873 Let me know how it goes. :)

[@AmericanReal23]

You should have taken some measurements on that o-ring that was causing the external leak - most likely a standard size. If the only thing wrong is a little external leak, that o-ring could be purchased for less than a dollar at a hardware store to fix your jack.

[@1947froggy]

Watch the video again. At about 10:00 I show another seal that needed replacing. Thanks for viewing. :)

[@AmericanReal23]

I know, but the next chap that rebuilds this jack may only have to replace that rod wiper o-ring.

[@1947froggy]

@@AmericanReal23 Mike if I am going to the trouble to bust open the jack I am going to replace most everything that wears. When I do plugs I don't only do the ones that look bad. But you are welcome to do the work any way you wish & thank you for the discussion. :)

[@AmericanReal23]

@@1947froggy I just repaired mine this morning, and my leak happened to be coming from the stem of the bleeder valve (part that has the u-joint). The o-ring size for that is AS568-011. Good as new and cost next to nothing. If you are cheap like me, it makes sense to disassemble and find out exactly what is leaking b4 paying $35 + shipping for a seal kit that you really only need one o-ring out of for repairing the problem. If I ever need to disassemble the ram, I will be happy to publish the o-ring size for the rod and also the piston cup seal (the P/N should be printed directly on the seal itself, and if not, a few measurements will find the correct size). Great discussion!

[@acadguru4972]

@@1947froggy Thanks Froggy. I too see the value in replacing ALL the bad parts if I'm already taking something apart, and there are many different types and materials of o rings. This kit worked great on model 50145. The cheapness of people makes me laugh :)

[@Resist4]

I have the Craftsman #50239 2 ton floor jack and mine seems to be leaking just like yours but it also seems to be leaking at the return spring.

[@1947froggy]

If you get the repair kit, it has seals for all the leak points. Thanks!

[@Resist4]

froggy that repair kit is kind of expensive though and I don’t have a 2” socket so I’d have to buy one and end up spending almost $100 to repair a 20 year old jack. I’m almost thinking it’s not worth my time to repair and may just buy a new one.

[@1947froggy]

@@Resist4 I completely understand that. :)

[@Resist4]

@@1947froggy I don't understand why these aluminum low profile jacks fail so often. I'm seeing a lot of people having the same issues with this type of floor jack. I have another Craftsman it's probably 40 years old made out of steel and it doesn't leak and still works great but it's heavy as all get out.

[@1947froggy]

@@Resist4 IMO the quality of the seals and the machining of the bore/seat that the seal touches has declined over years, you know the "throwaway" mentality. You have to be pretty determined to fix stuff these days, things are not built to take apart & be fixed.

[@paulsmith9341]

Froggy, how long have you had your 50240? I bought it new but i wasn't smart enough to save the receipt, only the manual which has a parts list but that list shows no rebuild kit. Thanks for the video! Thanks for the info!

[@paulsmith9341]

Sorry, I missed the date the first time I watched the video. 89 or 90. Sounds about right for me too

[@1947froggy]

I think around 1998. :)

[@drewparsons9721]

What size is the largest o ring?

[@1947froggy]

Sorry it's been years, just buy an assortment of sizes.

[@cikicikijancio]

hi, i have a simular jack 50239 but the problem im having is with the handle wont tighten up. i took the ujoint assenbly out and its not broken. dont know what to do next. what are the 2 "do not adjust" screws for?

[@1947froggy]

Don't mess with those, they control how much weight the jack will lift hydraulically but you can over stress the frame etc. You need to rebuilt where the handle turns the screw that controls bypass fluid. Too complicated to explain here. :)

[@fatb29]

Liked the video - thanks Froggy! There is another very in-depth video for this exact Craftsman 50240 1.5-ton jack that shows the complete disassembly of all seals, ball bearings and the infamous metal screen that can be found at kzbin.info/www/bejne/qZyTd3lsfKufp6M. The metal screen location can be found at the 33-minute mark in the video link, Hope that helps!
