I have an old floor jack that won't lift anymore.. I have added Hydraulic oil and still won't work. Like I said it's an old jack and well used. I need to know where I can't find the (how to rebuild) a floor jack. I sure there's not much to it but I like to have step by step instructions for something I haven't done before. If anyone can help it would be great.
The jack an AUTO SPECIALTIES MFG.CO. PRODUCT. ST. JOSEPH MICH. USA
It is a 3 Ton jack.
The Model #5-51215
Serial #03 81
I bought it at NAPA about about 29 years ago.
If anyone can help it would be great.
