Many years ago I when I was a new recruit at Nellis Air base training to be a crew chief we were required to do temporary duty on the flight line in the maintenance shops. I did repair big hydraulic jacks that lifted fighter jets. The floor jack video above is essential what we did, change 'O' rings. The video is slow and hard to watch, author needs a tripod, but does cover what to do. Only hassle will be hunting down proper size 'O' rings.
Thanks guys and thanks for the video Bob. I've been overwhelmed the last 12 hours changing web host providers for my website and another website I host and support. It's a huge hassle but necessary. Anyway....
The jack isn't a well known brand, don't even remember. Probably out of the same Chinese factory that makes them under many brands.
It isn't leaking fluid, it just leaks down (if that makes sense.) I might as well tear it down and see what I can do for it since it really isn't that useful at this point. I just had the second lift cylinder rebuilt on my 1998 Kubota loader, the other one started gushing fluid about three years ago. Fortunately seals were available for those cylinders.
You may be in luck with an easy fix. I think a jack that will not hold it's position and goes down has a bad release valve 'O' ring. At least try that first. Watch out there is probably a ball bearing that will also come out when you turn out the valve and that needs to go in or the jack goes no where.
Use plenty of petrolatum. We did that on the gear on the heavies. Extend the cylinder then slather it with petrolatum. O-rings aren't hard to find. You just need to any decent rubber company or even good year rubber. McMasters would likely have them also and they ship fast. Just remember the word slather when ya go back together with it.
My Scangauge II recently bit the dust. I liked that it recorded codes, but also engine values more accurately than the dash gauges.
Before I decide to do a direct replacement, what are you using that you like?
Has anyone else picked up Harbor Freight's newest, premium line of tools named Icon? I bought a long-handled 3/8 ratchet last weekend and put it to use yesterday for the first time. Its got a 90 tooth mechanism and seems just a smooth as my Snapon ratchet. Price was very reasonable at $50...
Oops, it looks like the sprinkler has been hitting the front left fender long enough that a golden haze is starting to appear.
The products I would use to remove these rust stains from stucco or concrete seem a bit harsh for auto paint.
Any suggestions for removing these stains?
All I have is Craftsman tools, probably if I had to guess at least thousands of dollars worth. Now the warranty my be gone:crying:
I made this multi-use bench top power supply from an old computer power supply I had lying around. It doesn't have variable voltages or anything a good store bought power supply would have, but it will work for a lot of general testing.
Computer power supply is advertised as 3.3VDC, 5VDC and...
