Hein Werner OS

[Elroy]

Elroy is feeling a little better this evening and was tired about being delayed with that damn plunger plug:

But we ended up with another little problem;

Yep that's a broken screw extractor. Actually it wasn't that big of a deal as there is access to the underside. Only had to flip the block over and drive it out.

Any who, we now "has" success.

The threads look good. That's just some old sealer in there.

And the threads are the correct 3/4"-20

We can now move on to finishing this up.

 

[W-Cummins]

Next time don't waste your time breaking off the extractor, just weld a nice big nut on it. This was the dream setup for the "welding nut fix" as you had a huge flange to weld to....

Elroy, A suggestion if i may... You might want to dry fit that plug inside the frame checking for end clearance on the sides and depth clearance on the bottom of the jack ( ie dragging on ground) By the looks of that plug it doesnt appear to be a "oem", I see it is recessed for the plug but it looks bigger than the original plugs. Both problems could easily be remedied but i would hate to have you paint it then have to fix the problem and paint again. Just my 2 cents...

Your suggestion on an mock up assembly is excellent and well made. The plug does indeed over hang the block. Not by much, but the point on the hex does over hang the main block by maybe a 1/32".

The parts lists Elroy has references the same part number for both the WS and OS jacks. All the plunger parts are the same for both the WS and OS.

This photo shows the original plunger plug for the larger Hein-Werner WS. The plunger shown in this photo is an after market replacement. The copper washer was Elroy's modification. The "plug" is OEM for the WS

 

[Elroy]

This photo shows the replacement plugs Elroy recently procured from Rusco Hydraulics. These replacements are identical to the OEM plug from the WS

The big question for Elroy is two fold.

Where the hell did this plug come from:

And Second, Why do what seem to be correct OEM plugs over hang the block? It's kind of a minor issue because Elroy will make it work.

That "round plug" seems odd.

PS:

The chewed up OD on this plug is where Elroy was trying to remove the plug with some vise grips. The plug was smooth to begin with.

Excellent! I have enjoyed this thread. looks like ALOT of work, but very nice. Hope your friend appreciates this. I would show him the photos. Thanks for the effort.

 

[Bolster]

Late to the party but Bolster just found this thread. Heaven help him, but Bolster DOES love these tool rebuild threads. Most gratified to see that a few men have the skills and willpower to do such things, and Bolster dreams that someday he too can perform this kind of mechanical (or is it maniacal?) wizardry.

Here's to Elroy This gopher's for you!

 

[Elroy]

Hope your friend appreciates this. I would show him the photos.

Elroy will find out the answer to that question when the jack is delivered and he opens up his wallet. He has been more than fair with Elroy in the past and have no doubt we'll be adequately compensated.

For the parts that is

The jack owner is fully aware that autopsy photos are posted on a site named The Garage Journal

Hey Elroy,

Neat project you've got going there! I've been following it for a while now and look forward to every update. As for the cost, no doubt the labor would have been the most costly part of this rebuild if it was totaled up and billed out, but since it sounds like you're doing it for parts only, it should come out much cheaper, not that it matters given the sentimental value. Nice to see people helping each other out like this.

A nice job to hiball too. Now I know where to got for parts!

 

[Elroy]

The last of the disassembly occurred this morning with the removal of the pressure relief valve from the main block. This valve is a safety device and Elroy debated about disturbing the factory setting.

Talk about a stiff little spring!

Notice the knurled drive on the adjustment screw. The factory made it difficult to remove/adjust with out the proper tool. Those factory efforts made removal only slightly more difficult.

Fortunately access to this valve is easy when the jack is together. So Elroy is going out on a limb here and is going to solicit ideas on resetting this over load valve. Elroy has a few ideas. How would you do it??

Ah... The ole "How tight do i tighten the overload spring question rares its head" this has always been "TOP SECRET" information from the manufacturers and ive never been able to get a definitive response from any of them. Lucky for me Ive got 20 years experience tearing these machines down and i always document how many turns it takes to get to completely closed on most all of my teardowns. For The HeinWerner OS/Ws jacks it normally ranges from 1/2 a turn to 3/4 of turn back from complete compression. This all of course varies due to Spring compression wear and tear over the years. Elroy when your done with the jack and running it thru its final inspection just aproximate 1 and a 1/2 ton and if you run into any by-pass just crank her down a little bit more. In all honesty you just dont want to get to the point of it completely locked down in order to lift 4 tons, It is a safety issue and exceeds the rated psi of the cup. And rember fellow Gjers Jack Stands are your friend its no fun being under a vehicle when you trusty or not so trusty jack decides to fail.

Most of the Early OS Jacks used a Round plugs, I have some early breakdowns that showed the rounded version and over the years they supplemented with the hex head. Who knows why? My guess is they wanted to make sure there jacks where repaired by "Hein Werner" authorized centers and similar to Walker/Lincoln they used fasteners that the normal man couldnt take off without damage to the parts. (Friggen Spanner Tank Nut....... woosabi... breathe... Inhale.... Exhale.........) Ok im back with you. In all honesty that plug wouldnt have had to been removed for Pump replacement account the top is beveled but in the short time im conversed with you i knew this jack wouldnt have been competed without total teardown and inspection which is cool. In a weird way..

That would make full sense. Got to take it in to get "approved" service.

Again a fully correct statement from a gentleman obviously fully versed in the subject.

To fully document these pumps, here is a photo that shows the bevel described by Hiball at the top of the primary pump bore. This "counter sink" corresponds with the chamfer on the pump guide. An unmentioned benefit of removing the threaded plug from the bottom of the block is that it allows loading the plunger from the bottom. This allows larger preloading of the rubber plunger cup with the 1/4-28 jam nut.

There is also some light pitting on the ram. Elroy polished it some but it's going to ride as is:

I knew this jack wouldn't have been competed without total tear down and inspection which is cool. In a weird way..

Well Elroy thought it was common knowledge that Weird = Elroy

 

[Elroy]

when.....running it thru its final inspection just aproximate 1 and a 1/2 ton and if you run into any by-pass just crank her down a little bit more.

That's the plan.

Thank you kindly for the confirmation

 

[Elroy]

It was a truncated Saturday with other obligations but Elroy did have a chance to assemble the ram, reservoir and plunger.

Friday night we started soaking the leather as per this suggestion:

I might add you still want to make sure the leather cup is softened before you do pull it thru otherwise it could damage the outside.***

Assembled the leather cup on the ram and pulled it into the cylinder per this suggestion

As far as pulling it into the cylinder that will work as well and is exactly how i install my most of my pump cups and vee packing cups

Screwed the ram and cylinder into the main block with a little sealer

Then took some RTV to seal the oil reservoir to the main body and the cap

tightened the assemble and installed the packing nut:

loaded the plunger into the body and assembled the springs and cups

At this point Elroy stopped to let all the sealers set up overnight before adding oil and the check valves.

 

[Elroy]

Elroy used a trick he learned as an apprentice.

Elroy wanted to cut a screw driver slot in the pressure relief adjusting screw and needed a good way to hold the screw while cutting the slot. Went to the parts bin and retrieved a bolt and nut with the the same threads (7/16"-20) and jambed the parts together to hold the adjusting screws

Over load pressure adjustment is now a simple procedure and the OD threads on the adjusting screw are pristine and untouched

 

[Uncle Buck]

Nice touch there ol boy! ^^^^^

 

[Elroy]

Well the cylinder is done and filled with oil. Pickles couldn't be happier

*Elroy thinks it looks just a "little" better

 

[Uncle Buck]

Gettin close enough to spit aren't you Elroy!

 

[Elroy]

Gettin close enough to spit aren't you Elroy!

Yep it won't be long now. Let the primer dry 2 or 3 days and hit it with some color later this week. It'll be finished up next week end if the "creek don't rise" and Elroy can post up a few finished photos.

So lets see, 9 week ends @ a minimum of 4 hours each makes 36 hours. There were at least two week ends there at the start where Elroy had a good 10 hour each. So that's another 16 hours. Call it 55 hours at $40 an hour or $2,200 labor.

So the bill is, plus parts.....................forget it.

That's exactly why these old things get thrown directly in the trash! Nobody can afford to fix them. Just like an old worn out POS car. It's cheaper to buy a new one.

The best thing about it all is that Elroy can clean up the garage and get onto some other more important projects. This thing has dragged on long enough.

 

[billymade]

Can you give us a "sneak peek"; on the projects that you have coming up, soon?

I'm going to spread some paint on the house. Want to come over and help??

 

[Uncle Buck]

I gotta do some of that myself Elroy, fun stuff eh.

 

[Elroy]

Damn right it is.

Especially knowing that all you have to pay for is the paint and few sundry items.

Wholly Moley. I guess a top-shelf rebuild has to cost someone dearly; this time it was Elroy who paid. And I think your $40 is way low for the quality of work. I have to admit I shy away from tracking my time on any refurb projects for this very reason...I really don't want to put a price on it, or I'd never do it in the first place!

 

[walrus]

I was hoping you'd tell what you had in it. Quality has its price.

 

[Elroy]

Elroy would be glad to post up a listing of all the parts. All the sales slips are under the windshield wipers of the the "85". Need to compile these aways for billing purposes.

 

[Elroy]

With two days dry time for the primer, the color is now on

 

[Bolster]

Kinda paint gun does Elroy use?

 

[Uncle Buck]

Kinda paint gun does Elroy use?

Rattle cans of Chevy Orange engine enamel Is my bet!

 

[heffneil]

Elroy is so good at this he peas and spits paint. Just depends on the color that you want to determine where it comes from.

 

[Uncle Buck]

Man, a new guy and you do know ol Elroy don't you!

Thanks for my morning laugh!!!

I hope it made Elroy chuckle too>

 

[Elroy]

Should we do this again?

And Elroys answer is yes we should. Yes we did

To clarify these photos:

The floor jack on the Left is a circa 1979 Hein Werner Model WS rated at 1-1/2 ton

The jack on the right is a circa 1948 Hein Werner O'Boy Model OS rated at 1-1/4 ton.

 

[Elroy]

And a few more detail shots:

Look ma no more bent frame:

 

[Elroy]

And the biggest question is:

Does it work ??

You're damn right it does

 

[Monte]

sweeet !!!! you should open a business....

 

[Elroy]

sweeet !!!! you should open a business....

Why, So Elroy could go broke? No thank you.

This work was performed for a close friend and was done for enjoyment ONLY.

 

[fatfillup]

Excellent thread and excellent work. What type of award should Elroy get? You **** is not approriate. You da man and you rock are over used.

How about "You da rebuild king".

Or maybe "Jack Master".
