How do i remove the rear drum from a 1990 chevy silverado 1/2 ton 4x4


After jacking the truck up and removing the tire look on the studs for the bolts to see if you see little flat wire clips on the tire studs if so remove them and then you should be able to pull the drum and it should come off. If it don't then you will have to release the pressure from the brakes against the drum. If the truck has had brakes put on before and the back plate adjustment hole have been cut out you can hold the automatic adjuster out of the way with a screwdriver and back the adjustment cylinder off with another screwdriver to release the brake pressure. Hope this helps.

Look for a rubber or plastic grommet on the cylinder in the jack. That is the fill hole.

What is a jack lift?


"A jack lift is a mechanical device used as a lifting device to lift heavy loads or apply great forces. Jacks employ a screw thread or hydraulic cylinder to apply very high linear forces.
A mechanical jack is a device which lifts heavy equipment. The most common form is a car jack, floor jack or garage jack which lifts vehicles so that maintenance can be performed.
More powerful jacks use hydraulic power to provide more lift over greater distances. Mechanical jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons)." (Wikipedia)

I have a 3 1/2 ton floor jack it is a craftman it will lift, but whene i put weight to it it will not lift anything where do you put the oil in to it. thanks gerald


Hi, Gerald -

You either need to top up the oil, or change the oil. Both of these are easy to do.
You'll need some high-grade jack oil, an Allen wrench, a rag or two, and a funnel.

1.) Relieve the pressure and lower the jack arm all the way down.
2.) Remove the tool tray from between the two rear wheels.
3.) Wipe the oil fill plug clean. (You don't want any gunk or debris falling inside.)
4.) Remove the plug with the Allen wrench.

Look inside. If the oil level is at or below the inner cylinder wall, you'll need to add oil. Don't go more than 3/16"-1/4" above the inner cylinder wall.

With the pressure still off, gently raise & lower the arm two or three times. Check and adjust your oil level again. Then screw the plug back in & tighten it with your Allen wrench.

Everything OK? Great. If not, repeat 1 through 4, then lay the jack on its side & drain ALL the oil out (into a container). When it's empty, set it upright & fill it. Again, raise & lower the arm several times.

Replace the plug, tighten it, then test. Raise the jack all the way up, then lower it all the way down, without any load on it. Repeat this two more times. (This helps to dissipate the air bubbles in the oil.) It should now be ready to use.

Craftsman 3 ton floor jack will not stay up


you need to bleed the air from the cylinder. there should be an air bleed or else you bleed it at the relief needle. also, if it still leaks down after you bleeed out the air, the seat for the relief valve or the seals at the relief valve cartridge are worn

How do you fill a ac delco hydraulic 3 ton floor jack model 34123 with hydraulic fluid


DONT KNOW WHO BUILT THIS JACK- AC DELCO JUST PUT STICKERS ON IT. TYPICALLY YOU REMOVE A PLASTIC SCREW IN PLUG OR A POP IN RUBBER STOPPER FROM THE TOPSIDE OF THE CYLINDER. WITH THE JACK ALL THE DOWN, FILL IT COMPLETELY UP AND IT SHOULD WORK. SOMETIMES THEY GET AIR IN THEM - JUST LEAVE THE PLUG OUT AND JACK IT UP A FEW TIMES, THEN INSERT PLUG. USUALLY 10 WEIGHT HYD OIL. OR "JACK OIL" AT THE STORE.

Hydraulic jack wont move.


Hi, A hydraulic jack is a pretty simple device, consisting of a piston/ cylinder, an oil reservoir, and a valve. You close the valve, pump the handle, which pumps oil into the cylinder and raises the jack. When you open the valve, it allows the oil to flow back into the reservoir and the jack will lower. If it still has oil in it, ( or is still in the up position) start with the valve, you should be able to remove it an clean it up. If you need more help, let me know. Good Luck, this should Fixya!
