Few years ago I bought one from a friend for £10...he got lots of stuff dirt cheap from a fire brigade auction. Used it a little but then sold it to my friend at the garage for the same money. Used it this year to push the tractor wheel rim on when I welded it. Still works great.
I wouldn't complain on only getting 42 years out of it. I had one like it for years, had all the attachments , spreaders, pusher and pulling rams, it was well worn out and took it to a auction and still got good money for it. Stupid me sold it and picked up a new one and it only lasted a short time and started leaking.
HEY BUDD, you mentioned that you werent going to do anything with the check valve- BUT, the tiniest little flake of crud or small chunk of rubber in the check valve will hold it open slightly and keep the pump from getting pressure as the oil will just freely flow back and forth...... So while youre waiting for the U-cup washers maybe take it apart and flush it both ways and clean and blow air thru the check valve to make sure it's good?
*HOLY COW! can't believe how much those washers cost. that's ridiculous. makes me appreciate my pora-power that much more. i have the 10,000 pound harbor freight one and bought the pulling ends so i can push or pull the dents and things out but i have to be careful because all my pushing elements are 10,000 pounds but the pulling ones are only 5,000 pounds but they still totally work*
had mine for 7 years now i think it is and used it on things well beyond the max limits and it's still together so i'm thinking i'm good but i never use anything harbor freight that i am expecting to last forever either so when ido use that it's very cautiously(normally)
are there 2 check valves, or just one? I would think there would be one near the hose, to prevent pressure from coming back through, and a second one between the piston you took apart, and the resivoir. I would think that check valve would be leaking fluid back into the resivoir causing your issue. those seals you removed look like all they do is keep the fluid from from blowing past the piston under pressure.
Hope you can get the seals you need ..I read the comments and seen there are some parts places mentioned. I would clean and inspect the check valve & clean/ flush out all the parts
I wonder whether Hein Werner's side trip into hydraulic excavators put them under. Many companies have tried to diversify into something that seemed like a good idea at the time, and went bankrupt.
If it suddenly failed, your check valves have failed. But the piston is pretty worn too. Broach the hole, and machine a new piston, or find something that is the right size. A valve stem from a huge diesel might be thick enough.
Hi Glad you found seals for it pretty easy. we have an old Dunlop high lift trolley jack here it must be from the 40's/50's and pretty rare. I can't find much about it online for pictures or anything. I need seals for that really as it leaks on the floor, but kinda scared to take it apart and mess it up completely if nothings available. My suspensions are it has leather seals that are goofy sizes and styles. The new made in China jacks aren't anywhere near as well built and don't lift so high, from what I've seen around. Like with your porta power it would be a sad day if it went in the scrap after all the money it's made and the years we've had it .
Nice when you can keep an old piece of gear alive, I have a chain come-a-long that is older than I am, Ive pulled it apart and cleaned it over the years, but other than that (And fixing the time I greased the clutch 25 years ago......long story) its working fine.
We used to soak rubber seals in mentholated spirits to clean and rejuvenate the rubber, I'm going back 25 years and we didn't have to do it often so I can't remember how long we had to soak them. I'm just thinking it might be a useful bit of info if you can't find replacement seals easily.
those washer should work the metal ring give them that shape and you add them as it wear so the brass nut doesn't bottom out you could probably just add a new one to what you have and keep using it
hey roadking! I rebuild graco airless sprayers and they have the same stile of packings on the piston and throat. there made of leather and teflon. have to soak them in oil for an hour or more before assembling. to adjust bring it to 0 play then give it a half to 3/4 turn. dont know if that will help but keep the vids coming i realy enjoy them! cheers!
I'm surprised a manufacturer would use 5 rings or seals in an area where one made for it would work. Great tool either way. Bet it works fine when you are done RK...
that pump looks exactly like a hydraulic knock out cutter set made by greenlee even down to the thumb screw just red not green colored they make parts for them try seals for that if you cant find them for yours
If all else fails finding sealing parts call Rodger's Industrial in Bettendorf IA. If you mailed him a rubber part he will have a replacement. He warehouses thousands of seals of all types, and I have never been told no there. He is very honest and intelligent. Message me if you need more info Roadking, and I will try to help if you need. I have no involvement with Rodger, just sharing the info.
Thanks alot Caleb!! I really appreciate your willingness to help!! I was able to pick up some seals and have it working now but thanks for the tip on Rodger's!! It sounds like a place that I might need in the future!!☺
Rodger still writes invoices with a pen and paper. Its a special place. Glad its workin, looking forward to part 2. Your welcome, its a community, and I like doing my part when I can.
I'm wondering if MVP11489 might be on to something too. I would think there should be 2 check valves, or at least a double valve. Anyway, I'm sure you'll get it straightened away. This is an interesting repair.
Thanks Reg!! Nah nothing wrong with the check valve, they're just ball bearings and springs!! I just had to replace those piston seals and now it's good for another 40 years!!☺
There you go then, well too, it is a Hein Werner after all ! I know that brand too,..there is no doubt at all they, like the older Ridgid plumber's and pipe fitter's tools, are the very best quality and built to do the job with very long life. Good ol' "Made In The U.S.A. ' quality,...like 'The Boss' signs's that title song.
What did you do for most of your working career, EJ? Good investigation. I dare say that you could get a rebuild kit for that since they were pretty standard and haven't changed much over the years.
We owned a Body and Paint Shop in the mid 70's, painted Battleships, Subs and Aircraft Carriers in the 80's and owned a Trucking Co in the 90's!! Packed it all in, in 98 and been retired ever since!!☺
Yeah, if it wasn't leaking out the plunger, that wasn't the problem. I would say check valve as well unless that release valve was not seating properly. Other than that, Could be the lack of paint ; --)
Washers for the porta power, they look exactly like my pressure washer seals. I bet if you get the specs you could find them at a pressure washer repair joint. ok buddy!
