When you replaced the packing seals did the copper nut fit down flush or did it stick up a little? I just rebuilt mine and it wont screw all the way down. I was thinking of putting teflon tape on mine also to make sure it dont leak.
I dont believe the nut should fit flush with new packing, If you have the correct amount and size and it was installed flat it should stick up a bit.
Now I am a proud owner of another true American made product thanks to Elroy and his rebuild project!!

..............Pete, p.s. keep up the good work......

Me again Elroy, Is there a difference between a OS Hein Werner and an O'Boy? are they one and the same or different, if so how? Just keeping you on your toes..............![]()
Lets put some numbers to these models for reference and identification:
The larger WS series jacks, rated at 1-1/2 ton (3,000 pound)
The dimension inside the frame on WS is 6-3/4"
1-1/2" Diameter piston.
**************************************
The smaller OS or O'Boy jacks are 5-1/4" between frame plates. We understand these jacks are rated at 1-1/4 ton (2,500) pounds
The OS ram piston diameter is 1-1/4"
It appears that BOTH jacks have the same 11/16" diameter plunger.

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.

Well progress had to stop on the Hein Werner for a few days because Elroy had a little trouble finding someone to borrow tools from so he could work on his "high performance twin turbo sports car"
Actually the power pack is going back together tonight and Elroy will post up as progress is made.![]()
Hey elroy I was wondering how you went about getting the cylinder out of the hein Warner jack you rebuilt a while ago without denting or scarring it??
Now this shots is "after the fact" but depicts the trouble encountered removing the cylinder tube. This damn thing was in there TIGHT and Elroy was concerned with putting a flat in the tube. To support the tube we found this Craftsman socket that fit the tube nice and tight.

You can see where Elroy polished out the teeth marks

It would be nice to see some detailed pics of your old 2 Ton Walker.Any plans on rebuilding the Hein Werner or the Walker?
That long frame Walker looks well suited for your truck. Looks like the handle doesn't even come near the bumper while your using it.
Well today was Hein Werner day for Elroy. Decided it was time to continue dis-assembly of the WS pump. What a dirty mess it was. Elroy is looking forward to having a rebuilt floor jack that does not leak !!

At this point the entire main body has been dis-assembled and cleaned. Can't get the main cylinder out of the block. That baby is torqued in there and the last thing Elroy needs is a dent in the cylinder so it's staying put. The over load valve also takes some kind of special tool to remove. Elroy understands it's pre-adjusted at the factory so that is staying put as well. All the parts in the relief valve are steel with no soft parts so there is no big deal leaving it alone.

The main bore is nice and clean with no pits or grooves. Elroy also wants NO DENTS so that damn cylinder can ride as is.

Dredging up an old post here. How did you get the tank nut off? Tried a punch but it was peening the cast iron "ears" of the tank nut, so didn't want to push it. Bigass spanner?

I have a question to Elroy. Did you use any loctite on either piston pump nut when snugging it up? Would the constant oil bath breakdown the loctite? Thank you, G

I believe mine has the punch marks as you mentioned but they both come off quite easily. I just want to make sure, no loctite? I have a few other questions, can I PM you? Im almost finished with the restore so just need some last minute questions answered. Thanks
