How fill an Old Bottle Jack

[sierramike]

I have old bottle jack that is part of long jack you use on a lift. It does not work. So I thought I would try get it to work by refilling it with oil. But it looks like the refill port is on the base and not 3/4 the way up the cylinder like on a modern jack. Does anyone know how to fill this type of jack?

Some pictures would be helpful.

tip it on it's side, remove plug, add oil.

Well you wouldn't be the first one to try and fill a hydraulic jack thru the valve system.. Normally the next thread starts out something like this.

"I tried to fill my jack, and ended up losing some valve components. Does anyone know what size of ball/springs and there order?"

OP.. Again pictures would be beneficial, but also look on "top" of the tank nut for a threaded Allen, some older jacks utilized a fill hole there.

Some of the old jacks used a rubber plug also but it should be in the outer tube shell as usual...

Ditto on needing the pics

OK here are some photos. The second photo shows what I think is the fill port. The third photo shows the check valve on the lower right. I think.

Very Cool.. Ive never seen a Stabilizing Lift with a Hydraulic Pump, Im assuming the Top part threads UP/Down to get it close then the Hydraulic part puts the finishing Pressure on? I looked thru my old manuals here at the House and didnt see anything that resembled it, But to answer your question. Yes.. I believe the Fill port would be the "Standard Screwdriver Plug". Obviously you will have to fill it either Inverted or on its side.

Thanks for sharing..

The correct oil level is about 1/8" below the fill port when the unit is laying on it's side IIRC.

That wouldn't leave much head room.. Do you have that jack? Trying to find a model number.

There was a similar one in a shop I worked at years ago and saw how an older tech filled it. No clue on model number or manufacturer. when it's laying on it's side with 2 legs in contact with the ground, the tube should be pretty much horizontal, maybe even tilting down a bit. The fill plug will be facing upwards at an angle about halfway between veritcal & horizontal.

I have no clue if he was actually doing it right or not.

Well its not rocket science I suppose.. Too much oil and it will have performance issues, too little and it will allow the ingestion of air and limit the lift. Is a fairly small jack, probably has somewhere around 6-8 inches of lift. There are some blackhawk tendencies with the base, but I can't find it in my books. Maybe he was filling it all the way up because it was a leaker? Lol.

I added some jack oil and now works fine. I over filled it at first and it would not go all the way down. So I remove some of the oil.

Glad you got it working..
