GJ Worthy jacks

Blackhawk S4 and Hein Werner O'boy restoration

I picked up some new to me toys today.

1 1939 4 ton blackhawk jack

and a little 1.25 ton Hein Werner o'boy

The hydraulics on the Hein Werner are about shot. It will go up, but only on the very bottom of the stroke. I'm hoping it just needs a quick rebuild and seals. I hope the cylinder is not shot. The 4 ton needs new wheels. The pivoting castors are almost worn to nothing. I'm sure McMaster Carr can source me a suitable replacement, but if anyone has a line on some originals or a good picture of the originals I would love to hear about them. Other then the wheels it is in perfect working order. Even has the little light cover intact.

Both jacks are going to get a cosmetic makeover. They are going to head out to the sand blaster and either powder coat or paint. Then they are going to take up continued service as working tools in my garage.

The blackhawk is a beast. It weights in at 290 lbs.

Nice finds! Hiball can help with parts and advice. Here's my GJ worthy rehab...a Lincoln/Hein Werner 93642 2 ton that I rescued from the scrap pile and rebuilt using one of Hiball's kits. I didn't bother with any lipstick for this pig, just rebuild and return to work!

 

[gte718p]

Already sent him a message looking for parts

dunno whether this one is 'worthy' or not......it is old, tho.

Its 'pet name' here has been 'jackosauras'.

I think its a 10 ton Walker, could be mistaken, its data plate is missing, can anyone identify it, and its approximate age?

We used this one for years and years, it looked like this when we got it, and there was never time/energy to restore it.....it finally had its main seal wear enough that it will lift a person, but not a vehicle....I shall have to get around to rebuilding it, one of these days....or would happily trade it for a 5ton, which is all we'd ever really need here.

cheers

I started on the restoration project this week. The rear casters in the BlackHawk were dead. I was not able to find any replacement casters.

These where the closest I could find:

Unfortunately the through hole was the wrong size and the were to wide. Not a problem. The old Walker Turner drill press made short work of that. (Did I mention I like vintage equipment)

Not exactly the finest example of a machine tool setup, but it worked. I ordered a proper set of hold downs immediately after I was done. After drilling, the hub was still too wide. A couple of minutes with a file and the fit perfectly.

Old and new:

One of the retaining screws for the castors was sheared. It was a little nerve racking with the easy out to get it to back out. The AFFF/Acetone mix penetrating oil did wonders. The bearings for both rear castors were also completely missing. Of course no one stocks them anymore and they are not a standard size. I think I've found some that I can make work. If not I'm going to have to have some bearings machined which should be interesting. I'm thinking about just putting a bronze sleeve in to replace the bearing.

I didn't take any pictures of the O'Boy. It is stripped waiting for blasting. I ordered the seal kit and paint for it. It was a pain in the @ss to get apart, but it is done.

 

[gte718p]

Anyone happen to know the size for the grease fittings on the front wheels?

 

[dewalt378g]

Nice find!!! Do you think you have original paint? I'm interested if you have an original color. A loooong time ago I bought an S4 rebuild kit from hyjacks.com. He, Richard if I remember correctly, told me that they used to be fire engine red which seems to be what you have. HiBall would probably know, but I'll check if I have grease zerks on my front wheels tomorrow and let you know the size. Also, I believe someone here turned out new bearing races for the rear casters on a lathe...if I find the thread I'll post. You might get lucky with the appropriate thrust bearings if you can find the right size.

I replaced the bearings on the rear casters of my S4 with some I found very cheaply available on Amazon. I determined the proper size by fitting one of the original bearings into a spot on a drill index.

 

[dewalt378g]

Ahh good 'ol Amazon....lol

Here's the thread anyway...lots of info

Very nice. The O boy may not have an issue they seem to have a very low engagement/swing arc. At least my walker badged version does and it has no problems lifting.

 

[Farmall 1066]

Nice finds. Glad to see them being treated to a restoration and continued useage.
Love the iconic looks of the Blackhawk.
Why can't anything be designed to be aesthetically pleasing today?

Although do realize those jacks were sold to professionals back in the day. But I agree, the worst is metal lathes. From lots of curves to all boxy.

It is not actually the balls I needed. Well, I did need balls as all of the balls were missing, but mainly I needed races. I'm not sure if the races were damaged by being used without ball bearings, or there were no ball bearing as a result of the races wearing out and allowing the balls to fall out. Either was the bottom race on one side looked like flat washer. The other still had its curve but was missing a good 30 deg chunk.

These look like the are going to work as replacements

They are a little thicker then the original. The bore on the jack is only 2" so the bearing is .09" over. I'm hoping I can make it work with some sand paper and call it light press fit

Ahh good 'ol Amazon....lol

Thanks. Eventually both jacks are going to be a bright red metallic.

The s4 works perfectly. As soon as I get the castors sorted I'm planning on putting it back in service. I'll paint it eventually. The O'Boy is torn down and will go to the sand blaster tomorrow. I'm hoping to have the pain in tomorrow and get it painted this weekend. The seal kit for it should be in next week and hopefully I can put it back in service.

I've got both the S-4 and the Weaver in one of the subsequent posts. Keep the updates coming, gte718p, as I'm keen on seeing how yours turns out... it's going to be a bit before I can start on a proper restore.

I'd really like to know how that happened.

I'm not sure if I like the truck or the jack more.

I've got the same one, albeit no service box.

 

[zkling]

I'd really like to know how that happened.

$,greed, consumer demand, profit margin, increased population, etc.

Today I think one the the nicest looking and working jacks made is a milwaukee, but very few folks are willing to spend the $ for one. But again it is designed as a professional tool, targeted to pros.

 

[gte718p]

So the bearings didn't work out. Re evaluating.

 

[dewalt378g]

Ok, so got home and checked out my zerks. They are drive type and some basic measurements (without pulling them out) they referenced to SAE K516-SBA http://www.saeproducts.com/grease-fittings-K516SBA.html

which is also Alemite 1699 or Lincoln 5030

But check the hole dia so you get the right fit or just tap it. Here is a chart that you can go by drill dia for drive type

[dewalt378g]

Yeah pics were missing for me too, but it's well described. Dude, that color is going to be amazing.

 

[gte718p]

Thanks for the info and the link. I had never heard of pressed in grease fittings.

After:

I still have some clean up to do with the wire wheel. The blaster (not mine) was almost out of media. The window was so scratched there was only about 1 sq inch you could see through. All and all a quite frustration two hours. However progress was made. It looks like the paint will not be here till next week due to the holiday.

 

[gte718p]

I finally got the pump section apart around 1 am yesterday. It refused to cooperate. Penetrating oil, a pipe wrench, and a larch cheater bar proved to be the magic combination.

The pump and release came out fairly easily. After soaking in some penetrating oil the spring and ball assembly came out easily.

The brass packing nut came out without a problem.

This is where I stalled. I could not get the outside of the cylinder off.

Finally after a couple off hours of soaking in penetrating oil I broke out the cheater bar and it came apart.

Cute little one at work.

For reference that cans a little over 4 m in diameter, and that's a boom welder in the back.

Epoxy primer went down today.

Color and clear do down tomorrow if it is not raining.

Sprayed color and clear today on the O'Boy.

Came out more burgundy then red. With the pearl in it it really pops in the sun light. Unfortunately the day turned crappy so I had to put up all the walls of the tent and work inside. Pictures don't really do the color justice.
I'm debating if I want to attempt to color sand and buff. I sprayed the Harbor Freight crane I have on the back of my truck b/c I had extra paint. I am going to experiment on it first.

Since I was literally watching paint dry a good portion of the day I started working on the Blackhawk S4 light. I'm not sure it is actually useful, but its there and now it works.

One of the Harbor Freight free LED flashlights gave its life for this repair.

I started by taking the batteries and switch out of the flash light. I then used a dremel to cut two slits in the side of the light. That allowed me to slide the lens and LED out.

Solder wire to the pads on the back of the LED,

Slide the wires through the holes in the case and up the handle. The lights battery pack slides right into the handle in the original location. No wires attacked in the picture. They are simply soldered to the tabs on the battery pack.

Switch goes onto the end of the handle.

The switch is a little small for the opening. Right now I just have several layers of electrical tape wrapped around the switch to make it fit. I'm going to have to come up with something better. It looks like I'm going to have to have bearings machined, so I might have a new switch plate machined while I am at it. Or maybe just get some derlin and machine and adapter to fit the two together perfectly.

Anyway the end result is a functional light:

The bearings in the blackhawk wheels were completely shot. For the life of me I can't find a suitable replacement. Right now I have some thrust bearings in them. They work okay, but don't provide the axial support that is needed for the wheels to turn.

There is a thread on here where a guy made is own. Unfortunately he has not logged on in over a year and a half. I would love to get his dimension, but I'm not expecting much. I've designed a new bearing. Unfortunately I'm working with a new program and I can't for the life of me figure out how to make dimensioned drawings.
Even though I'm frustrated with it right this second. I highly recommend FreeCAD. It is a really powerful parametric program. It can do Finite Element analysis, motion analysis, all kinds off cool things. Best part is it is free

I really want to 3D print these bearing to ensure they are going to work. They are angular contact with a fairly large contact angle. It is less then idea, but since they are extremely low RPM I think I can get away with it. Unfortunately the company I ordered my printer from has delayed and delayed and now they are saying early next year.

If anyone is willing to print them, I have uploaded the IGES files in a .zip. I'm more then happy to contribute some $. I know PLA and machines are not free.

If you happen to know where I can source a 2" OD angular contact bearing with 1 1/8 bore that is .37" thick I would appreciate it. I'm also thinking about just doing a solid piece of bronze bushing stock. I'm looking for opinions on that as well.

 

[gte718p]

The O'Boy is done.
Before:

After:

Most importantly it now works. The paint is not as hard as I would like or think it should be. Paint and I don't seem to get along. I have some touch up to do. I also think I'm going to give it another coat of clear down the road.
With grease fittings on each wheel and newly rebuild swivels in the casters this jack is a joy to move around. It rolls amazingly. I can't wait to put it in service.

 

[gte718p]

I don't think anyone is actually reading this thread.

I was reading jack threads on GJ yesterday. Someone cleaned up the image of the ID tag on an old jack and had a new tag manufactured. It looked really sharp, unfortunately he was kind of an @$$ about sharing the image It rubbed me the wrong way. In any case it was not hard to do.

I scanned the original tag at 1600 dpi:

I used GIMP which is a free program to straighten up the image. I used the threshold command to convert it to black and white. I went in with paint brush and cleaned up the imperfections in the image. Its not perfect, blown up you can see imperfections, but the tag is only 2.5"x2.75" it prints perfectly.

It is off to the printer and in a month I should have a new tag.

Nice job on the rebuilds.

 

[themiller]

I'm here and reading. Nice job on the restore. Kinda crazy the capacity is 2500 lbs for that huge jack!

 

[Garage Junky]

That O'Boy came out awesome! I give you a lot of credit for getting that project done so quickly.

Love the light on the Blackhawk. I may just borrow that idea

 

[Skyline]

Reading.....Good Job on the H-W.

Nice work! Thanks for sharing and taking the time to photograph your work. Threads like this really help me out when I'm restoring tools.
I love my O'Boy. Perfect jack for my little home weekend warrior garage.

Finally made some progress on the S4. I ended up designing a simple sleeve to adapt the bore to modern thrust bearings.

You can see the wheel stud, the sleeve, the thrust bearing cage, and a couple of shim washers.

Thrust bearing and shims stacked up

Sleeved

I haven't greased the wheels yet, but it rolls extremely well. I'm not planning on greesing it until after paint however, I expect it will be amazing especially considering how much it weighs. Unfortunately I just found out I'm going to be spending 9 months in a very hot sunny place that is not my home. It is probably going to be late next year before it is finished. Oh well its been waiting since 1949, I don't think another year will hurt it to much.

mtnwkr: your build is one of the ones that inspired me to do this.

The Hein Werner is back in full service. It rolls absolutely amazing. It really is a pleasure to use. I used it last week to lift my 4runner for brake and transmission work. My only complaint is how low you have to be to actually engage the pump. The handle is almost horizontal before it starts to engage the pump. Full stroke is really short. It makes since and works well under small cars, but on my trucks it seems like it is wasting a ton of potential stroke.

 

[gte718p]

My local printer failed me. He has been jerking me around for weeks about getting the metal tag printed for the Hein Werner. Anyone have aplace online that they have used for metal printing?
