I am talking about my old sears floor jack -
I had to add a 2x4 to get it high enough to get the T wheel off the ground today.
It has been getting worse over the last few months
The up movement gets less and less as it gets higher so I think it needs oil.
Does anyone know where to add oil.
if you raise the arm so that you can see the assembly underneath you should see in the "bottle"
either a rubber stopper or an allen screw (depending on the age) open that up and put in 1 oz of fluid and slowly pump to get any air out then put the plug/screw back in unless it has been obviously leaking that should be about it needs if it needs more then you may have bad seals.
Remove the cover plate and it should expose the cylinder. There should be a plug on top of the cylinder. Remove the plug, install hydraulic oil. Pump (raise) the jack as far as it will go then release. Check the oil level again.
The labeled cover should just snap off.
Yes. you are low on hydraulic fluid. If you can find the model number, you should still be able to find an instruction manual online since Sears is such a prevalent name. The manual will show you how to service the jack and what the best oil is to use. On my floor jack, the steel screw-in plug sealing the hole where the hydraulic fluid goes in is located on the side of the base of the cylinder at the opposite end from where the shaft comes out.

Thanks guys - I will add oil this AM before we we head to the annual Memorial Day Parade
Had one of those Sears jacks for 40 yrs. Made in USA. Finally puked. Bought another Sears jack just like it. It was junk. Made in China. Took it back and got another one. Works great. Found a tag on this one telling me if it don't work to do something but I can't remember what the tag said. (Senior moment)LOL
You can open up the cylinder and drop in a Viagra tablet but you have to wait a while before you can get your car down. If it stays on the jack longer then four hours then contact your mechanic.
It worked. I found the rubber plug, added oil, and jacked up the car.
Good thing I didn't use Viagra because I needed to get it on the ground so we could go to a parade
BTW. The Sears instructions said to add oil through the fill hole but didn't say where it was
Here are a few pictures from the parade that my wife and grand daughter took.
We were the only "old car" but there were a bunch of old tractors
Woops missed this one
