Snap On YA 642 jack

Net Wurker · Jul 23, 2012

Hi. New member here, first post.

I have an older snap-on branded jack, YA 642. I bought it used off a Matco distributer back in the early 90's. It has been a wonderful jack, but recently it won't pick up a load anymore. It will get a car off the ground, but as soon as the full weight of the car is off the ground, it creeps back down.

I guess it needs the hydraulics rebuilt.

I read through some of the older threads on here about these jacks, and it seems a member on here, Hiball, sells kits for these? I beleive the consensus is this is probably a snap-on branded Lincoln jack?

I need a kit and also some instruction, as I have never rebuilt a hydraulic pump before.

Any help is appreciated...here are some pics.

Hiball · Jul 23, 2012

Here is a Link that fellow member GeorgiaHybrid put together that goes over the basics for this design (93632 versus 93642). I do keep those kits in stock all the time, If you have any questions dont hesitate to contact me via PM.

GeorgiaHybrid · Jul 24, 2012

You have a nice jack and even better, it is cheap and easy to rebuild. Hiball can get you a kit and a couple of hours in the shop will have it running like new.

Welcome to the forum.

Net Wurker · Jul 24, 2012

Yep. Within about twenty minutes of posting last night, I have a rebuild kit on the way from him!

And he also linked the thread where you did a nice pictorial on how to rebuild this jack. I'll use that for a reference when I start on mine.

Question for you...what size is the socket you used to make the "special" spanner nut remover? I'll need to do the same thing. I have a Harbor Freight in town, so I should be able to find a cheap china socket.

This forum is great!

GeorgiaHybrid · Jul 24, 2012

It is a "Budd" socket for the wheels on a tractor trailer rig. I think the size is 1 1/2"x13/16"

Net Wurker · Jul 24, 2012

Thanks...so I guess I'm looking for a 1-1/2" in a regular (cheapo chinese) socket?

GeorgiaHybrid · Jul 24, 2012

If you have a cheap tool store nearby, try finding a budd socket. They are heavier than a regular 1 1/2" socket as they fit two different nut sizes.

Net Wurker · Jul 25, 2012

Well. my local HF didn't have any Budd sockets. But I found one on ebay for 12 bux. I'll need to get a 1/2 to 3/4 adapter, and hope my little 21 gallon compressor can supply enough 'oomph' for my impact to break it loose.

You really crafted that 'mod' to that socket in 15 minutes? That's impressive

... it will probably take me an hour or more.

GeorgiaHybrid · Jul 25, 2012

I have a little bigger compressor than most....A cut off wheel and a big ******* cut file had the bulk of it done in about 10 or 12 minutes. It doesn't look pretty but it does work. If you have a structural steel fab shop nearby, ask them if you can go thru their drop pile for some real short pieces of 1 1/4" to 3" pipe. They use a lot of schedule 40 and 80 pipe that can be adapted to a lot of specialty tools.

If your compressor doesn't have enough "oomph", take it to a freindly tech near your home and have him bust it loose for you.

pop pop · Jul 25, 2012

GH and Hiball give good advise. But you're gonna need to get up around 500 -600 ft # of torque if that ****** is coming apart for the first time.

Net Wurker · Jul 25, 2012

Yeah, I'll probably end up having to take it somewhere to get it popped loose.

jokerg · Oct 9, 2012

ok i'm new here and want to thank everyone in advance, I also have a YA 642 Snap on jack series a that i need a rebuild kit for. I bought one kit but the size for everything inside the cylinder is wrong outer size is too big inner size is too small. if anyone can help me to get right kit or if they know what # kit is right. i got kit # 240-524 once again thanks in advance

Hiball · Oct 9, 2012

Pm sent.. Jokerg

bhalv · Oct 9, 2012

I love seeing the same 3 guys chime in on every thread related to these jacks, maybe I shouldn't have been supplying pop pop's habit.

pop pop · Oct 9, 2012

Brent, You've changed my hobby from garage/restoring my old vettes to a jack hobby! I've got 3 now disassembled and blasted and primed. Trying to get them all disassembled, cleaned and determine what parts are needed.

DHS · Oct 9, 2012

I recently picked up a YA700 Snap On jack that need rebuilt and got the kit from Hiball. Everything went smooth and did not have much trouble with the big nut. Impact hit for about 10-15 seconds and she was off. Good luck, I am glad I fixed mine. I could not buy the equivalent jack today for anything close to what I have in mine.

Thanks again Hiball.

Pictures? Wouldn't mind seeing what you are rebuilding.

pop pop · Oct 10, 2012

OK Jeeper. Here's the 'to do" pile:

And these are "in progress" sandblasted, and primed:

The one on the right is painted, but without the hydraulic unit which is on the bench to be rebuilt with Hiball's kit.

These are all Walker mfg. jacks. Some are labled Lincoln, Snap On, NAPA, but are all Walker 93630, 93632, or 93642. All very similar, but with minor production changes. I'm still learning about them and developing a list of hard parts needing replacement. You can find details of the hydraulic rebuild on a thread from GeorgiaHybrid.

pop pop · Oct 18, 2012

Here is another update for Brent's pleasure. New compressor and back to blasting and painting frames. The blasted one is the SnapOn/Walker 42 model. The disassembled one is a Lincoln/Walker 42 model.

The assembled frame on the right is a NAPA/Walker 32 model and the one on the left is a Walker 32 model. Don't understand why the Walker had the silver blue paint rather than the dark bllue, but... And also, the SnapOn didn't have any white paint on the handle or wheels - all red. Does anyone have the 42 model SO with solid red paint?
Duh, didn't need to look far. The original post is all red and the same jack.

bhalv · Oct 18, 2012

Those are looking great, nice to see some old steel coming back life

pop pop · Nov 9, 2012

OK, here is some more eye candy for jack lovers, and some information/question for Hiball.

These two Walker jacks are the final two of this series to disassemble and degrease and just wanted to note the differences before blasting and paint. Even had thoughs that one may not be a real Walker and hope you will be able to provide a narrative. The one on the right is a typical 93632, but the earliest design as best I can determine with the double flange for the caster wheels. It is basically a sheet steel fabrication with some cast parts like the saddle. The left one is the strange one. Note the oversize axle fully welded in rather than a one sized shaft tack welded or not welded at all. The fulcrum is not welded plate, but a cast piece. The saddle is different as well. The saddle pin holds it in place rather than the rivited base on the typical one. The other difference noted is the packing nut on the tank is a hex and not the two slots used to fasten/remove it.

More details of the typical 93632 parts.

More detail of the strange unit.

Eye candy as the work progresses. Don't ask why I'm doing all these. I don't know. But we lean heavily on Hiball. Thanks Steven.

Hiball · Nov 9, 2012

The Strange Unit is Probably a 93642, Or sometime during its lifetime the Unit was swapped out or the Tank nut style replaced. Seal wise.. the 2 models are identical outside of the Older 93632's using Leather Piston seals/Packing on the Nut versus Poly/quad ring.

pop pop · Nov 9, 2012

Thanks Hiball. The block looks like the other known 93642's as the 32's are basically a billet. You've seen the cast fulcrum arms then? The saddle pins are the same as all others, and rusty!

Jeeper · Nov 9, 2012

Pop - Nice work. Love seeing the old ones restored. I keep looking for some around central texas but haven't seen many.

pop pop · Nov 11, 2012

Ha! I think they all congregated in Va.!

123Go · Feb 4, 2013

Thanks for all these pics/info guys!
Its fantastic work you have done on those jacks & on this site too Pop.

The answer to "why your doing all those"? To save them from cow patty hell! lol

We all appreciate every ounce of your hard effort in doing so. Only wish you were closer so I could watch, help and learn from you in person.
Awsome work and again everyone...Thanks!

p.s.- Pop' I believe your correct saying the good ol' jacks congregated in Va. they're not in Indiana either, all that coal must be magnetic?

Jeeper · Feb 23, 2013

pop pop...any new photos? Are they done yet.

pop pop · Feb 25, 2013

One of the 93632's is back in service. We've been together for about 35 years! Hauled it down to Ga. recently to do some work on the vettes. I've gotten more kits from Hiball and if the garage ever warms, we'll have some more up soon. Will hit a wall soon for missing hard parts though. I have 95% of 8 jacks, but only 100% of 2 or three.

Sounds cool. I still want to know how you have come across so many 642/632s. I hardly ever see them come up on Austins craigslist. I luckily got the one I saw. Wouldn't mind rebuilding more.

pop pop · Feb 27, 2013

Well, I didn't find them first. Young man in college found them and sold me most of them and then offered the rest when he graduated since he hadn't found time to work on them. I was just looking for a very few hard parts and decided to buy them all. Don't have a clue what I'll do with all of them when finished, but as you know, when you see something like this it's hard to pass them up.

123Go · Apr 6, 2013

Hey Pop Pop'
You could advertise them on Craigs list? I'm sure you'll have no problem at all selling them. Hiball or other members may have better ideas about were to sell them?
Sure wish you were closer. My bro needs one. He bought a Cummings branded {shinn} off a truck and just hates it, because it has star release and its hard to control. He saw Cummings sticker and thought it would be great. Jack business is such a racket.
I'll find one close by for him though. Looking forward to seeing pics of your progress. Weathers getting warmer here, thank goodness.

pop pop · Apr 6, 2013

Thanks 123Go. Don't know where you are, but not sure I'll be selling. At least I'm not doing them with that in mind. I've two of the 93632's of the old configuration I know have a home with me. One has for 35 years already. I've about finished a SO 642 that will probably go to my son. I have two sons, so there goes the HW 93642. My brother needs a good floor jack, so that would be the remaining 93632 assuming I have the parts. What's left I'm uncertain will be enough to make a good assembly, but we'll see. I'm traveling for a while, but when I get back I'll update the pictures to show the two 32's and the YA642 as they should be finished except for some repair to the handles. Thanks for the ideas.

Oh, the old Walker 883 has been with me so long, I could never part with it. Best junk yard tool you could have. Light enough, strong enough, low enough and the handle is removable.

pop pop · Jun 3, 2013

Well, its been awhile so here is another ressurected one from the rust pile. Two 93632 Walkers and a 93642 Walker (actually a SO YA642). Been using the one near the garage and just finished the SO. The center one you can see is why I'm still waiting for Volaredon to ship me a spare handle. More to come later. My sons are anxious for me to deliver one to them.

Jeeper · Jun 3, 2013

Bravo, bravo,bravo!

pop pop · Jun 3, 2013

Anyone out there know of an adhesive to put the labels back on? They seem to be a plastic film with used "sticky" on the back that no longer sticks.

Epoxy cures everything! I haven't forgotten about the screw nails for the tags and the rear cover, I still haven't gotten my pump apart yet!

You can always scan the labels and re print them on new adhesive label stock. Or as Snap On. My Walker is devoid of any labeling aside from the yellow model tag which has been partially painted over. Not sure if I can save it.

I have 98 of the nails if you get ready for them!

I stripped these and blasted to grey metal first, so everything came off label wise. I saved them, but no sticky left. Just have the ser. # on the handle yoke.

Greetings fella's & pardon me for butting in . I have the red painted version sold through snap-on that I bought over 20 years ago . It has leaked fluid from the vent plug on the tank when letting it down from day one and after about a dozen uses the fluid has to be topped off so I just stopped using it and bought another jack . Has anyone else experienced the same issue or know what the solution to this problem might be ?

The proper oil level should be aprox 5/16" below the full mark or the oil should rest just above the inner cylinder when peering thru the hole. If your snap on model utilizes a threaded screw, you need to keep it loosened during use to allow the reservoir to vent.

pop pop · Oct 28, 2013

Well, it's time for the final chapter on these jacks. Except for some minor issues they are ready to go back to work. Need to install the bottom cup/shield on one pump from Hiball (thanks HB), then find a couple of bushings for two casters. The SO is back in the picture as I had to rework it and one other. Had to cut new seats for the valves as they would not raise. Apparently too much water had sat in them before arriving here. These are in addition to the three above plus the reworked SO. Enjoy.
