Floor jacks are remarkably similar, despite small differences. Some of these things would be very helpful for the proper assembly, too. There is a very helpful link at the e-How page that takes you to a set of photos and some useful notes on critical stages for doing work on a low price imported hydraulic floor jack. e-How does offer a step-by-step procedure for rebuilding a hydraulic jack in text, but it is quite general. The Blackhawk Parts web page offers a few cautionary and a few safety notes, but no helps on the rebuild procedure for the Saturday mechanic. The rebuild kit does not include any instructions. And, I do not want to risk losing any parts by opening the bag early and having something roll out. It will help, too, if an exchange were necessary. In the photo you can also see the paperwork that came with the parts kit. I will have less difficulty exchanging an unopened parts kit than I would have trying to exchange a kit I had opened, in case the wrong one was shipped to me. I decided not to open the parts kit until I was certain the parts it contains match what I see on my jack as I dismantle it.

There are also some steel balls and copper washers. Some are of neoprene molded to special shapes. There are 19 separate parts in the kit, including a number of "O" rings. The photo shows the parts kit I received. Some suggest saving money by simply buying a few new "O" rings at a local hardware store, but that would not be a sufficiently complete rebuild. That is a fairly typical price for a rebuild kit.

I paid about $45 for the parts kit, plus $11 shipping. Although my jack has the Fleet name, it was actually made by someone else. The kit I need is not the one I would have thought, but is actually for a Lincoln/Walker jack. So, I sent an e-mail to Blackhawk Parts with the name of the manufacturer and the model number.

It should have been easy to find my jack among the listings for Fleet jacks on the Blackhawk Parts web page and order the appropriate rebuild kit, but it was not. I found Blackhawk Parts and ordered parts on-line. Several firms sell rebuild kits for hydraulic jacks. The procedure is to place the jack over a large pan, remove the filler plug, turn the jack on its side and let it drain.

#GRAY TRANSMISSION JACK REBUILD KIT MANUAL#

I did find one manual for a floor jack that said the fluid should be changed every year. Brake fluid makes the seals swell.Īt this link you will find one man's description of how he rejuvenated his twenty-five year old jack by flushing its insides with a solvent, letting it dry completely, and filling it with fresh hydraulic jack fluid. When putting fluid into a jack never use anything other than hydraulic jack fluid.

Doing that will allow you to download a PDF of this Instructable for printing, or to view at any time later on your computer, assuming you wish to consult what I have done as a guide.

If you want to attempt rebuilding a jack and you are not a member of Instructables, I would encourage you to pick a password and a screenname, and join. Further, I had to make several special tools to get the job done. Rebuilding this jack was much more difficult than simply replacing a few "O" rings, and it required more than the very few hours some say are required for rebuilding a jack. A word of caution: Rebuilding this jack presented several challenges that seemed almost insurmountable at the occurrence of each. From what I have read, forty years of service is a reasonable time for a hydraulic jack to operate before it needs a rebuild. If filling with fluid and purging air from the system do not restore function, there is probably internal leakage, even though fluid is not leaking from the jack. Finally, one day, the lift arm would not rise at all. At that time I raised the lift arm with the handle, released the jack's valve, and let the arm fall slowly several times to purge air from the system. A few months before this problem, there were bubbles coming up through the vents at the filler plug. I checked to be sure it was adequately filled with fluid, but that was not the problem. (I was able to pull the lift arm up by hand and it settled slowly enough that I could make a photo with the arm partially raised.) The lift arm no longer rises when the handle is pumped up and down. It began to leak down a little a few months ago. This is a 1 1/4 ton hydraulic floor jack my father passed on to me.
