Hein-Werner jack question

[brickG-man]

I own a Hein-Werner 2 ton floor jack Winner Series Model 68054. I got this jack in 1987 as a Christmas present from my folks. It has been a good jack even even though it's made in Taiwan product. Lately it has been acting up; not pumping a full stroke and limited in height. Before anyone asks or suggests, the fluid level is correct and it has been purged to make sure that there is no air in the system. I suspect that it may need rebuilding after 26 years. I have written to Hein-Werner to see if parts are still available. I haven't heard back yet however I have never had much luck with Chaiwanese tools especially after 26 years. I guess I am looking for opinions here as to if they think that parts will still be available or if there is someplace in which I can get the jack rebuilt. There is some sentimental value to this nice little floor jack since my parents gave it to me so I would really like to get it fixed.
Thanks

Contact Hiball on this forum or wait until he sees this.

No parts or seal kits available. If you need seals, you will have to measure them so you can order.

The current HW ownership won't be able to help you with sourcing any parts, based off the linked drawing above it appears its a smaller trolley jack. Obviously it doesn't have much monetary value, but I surely understand the value that comes with sentimental items, and the individual seals are available and to be honest very economical to replace. My recommendation is to rebuild it yourself, there isn't too much too those little jacks and if you take your time, work on one section at a time, follow the exploded view diagram, I think you will come away from the experience very satisfied. If you have any questions don't hesitate to contact me.

Just as a test, remove the oil filler plug and try raising it again. If it raises normally, then the problem is the seal in the pump piston. Being so old, the seal is no longer sealing properly. With the oil plug closed, there is a vacuum created inside the oil tank every time the arm is raised. This vacuum increases with every stroke and if the seal is leaking, it won't be able to overcome the vacuum created in the oil tank. The pump piston draws oil from the oil tank by suction, so with each stroke, less and less oil is drawn until the pump piston fails to move oil. Removing the plug prevents the creation of the vacuum. That type of pump piston has a small nitrile u-cup, which should be available in your local hydraulic shop and, if not, check a site called "theoring store".

The most common sizes for these pump pistons u-cups' outside diameters are 11mm OD or 12mm OD. The inside diameter is usually 5mm, but check this by measuring the actual part.

Thank you Edgar and others. I forgot to mention that I always keep owners manuals so I do have the original owners manual and 90 day Limited Warranty but thanks for sending JCRCnow. Does anyone know the best source in the Chicago area for hydraulic parts?

You can buy them from Hiball, ...I think.

I'm not for sure what area of Chicago your in, but there has to be numerous hydraulic shops in the area. I would simply open the phone book, make some calls and let them know your looking for some metric Ucups and would like to bring your old seals in to match up to New. It's always a good thing when you can patronize Local business's. With that said... Replacing both Ucups and Orings shouldn't cost more than $20, and that's with them making a profit.

I can, and Do ship seals out when requested, but always encourage local business patronage.
