bottle jack (stupid question)

[rmuller]

Okay, this is definitely a stupid, but important question.. where exactly do you position the bottle jack to lift the disco to change a tire? The last time I changed a tire, I was 12 and it was on my dad's audi.. the trucks manual is very ambigious.. just want to make sure I know exactly where, just incase.

thanks

under the axle, that should work

For a Disco II the correct place to jack from is the notch on the radius arm. The top of the bottle jack will fit in there. The picture on the previous post looks like a disco I it might be different.

It is a D1, but I don't see why the instructions would be any different at all. That is what my manual says.

I wouldn't put the jack under the radius arm!
That's a lot of weight for a support piece.

Put it under the axle, the slight "U" on the piston top fits the axle nicely.

Or, you can dig a big hole and hang the wheel into it.

what he said.

radius arm bad idea. especially since its a D1 and your jack is old and probably hasnt been used in awhile. those hydraulics can break pretty easy.


i wouldnt lift my truck with anything less than 4 ton floorjack. sure it cost me a hundred bucks.

but it's your fuckin head under there.

To that point, I don't care what the jack is, you shouldn't ever get under a vehcile that's only supported on a jack. Jacks by their very nature raise and lower a vehicle, which means if they fail, in all likelyhood the vehicle will come down. (some heavy duty professional quality jacks have dogs in them to prevent that, and they are excepted)

Use a jackstand to support the vehicle if you are going to be under it.

Now lets get back to the point, he is only changing his tire.

back to the point. The axle where you have the jack is a fine location and close to where I place my jack stands (unless they need to be on the frame that is.

Where do I get one of these?

From Muskydisco's post:

I understand it's to raise the bottle jack up a couple of inches, but where do I get one?

Hi-lift makes them to go with their jacks.

This is an internet forum. Get back to the point? You anarchist!!

Crap Anyway, yes that is the offroad base for the hi lift jack. You can get them just about anywhere.

I have a hard time trusting a bottle jack that lives under the hood next to a very hot internal combustion engine. That just ain't right.

I don't think I'd carry a 4 ton floor jack around to change a flat tire.

Nope, wouldn't use floor stands to change a tire in the Kmart parking lot either.

Let's see...I'm back to digging a big hole and hanging the tire in it or using my bottle jack!

Seems strange to put a hydraulic piston, sealed with rubber rings, next to the heat of the engine. But that's just MHO.

Anyone ever experience the failure of their bottle jack?
Does it come down all at once, or is it a creeping let-down?

Survey of one, but...

I've changed tires on my D2 twice, both exactly according to the instructions in the manual (kind of guy I am, all anal retentive and stuff). The notch in the radius arm is correct; that's where they want you to put the jack, and it works fine. As for the speed with which the truck drops when you release the jack, you can control that by how fast you crank the valve open when you're done. Finally, my bottle jack lived under the hood, undisturbed, for four years before called upon, and seemed none the worse for wear.

A bit of unsolicited advice: the wheel chocks are a good idea.

YMMV.

Good luck!

 

[MUSKYMAN]

I agree...use the notch on a DII and the axle on the D1

also dont fret the bottle jack it will out live all of us

Wasn't suggesting jack stands for tire changing. I was responding about not getting under the vehicle with less than a 3 ton jack. If you're getting under the Rover to change a tire, you have other issues.

Not the rover one, but have seen hydraulic jacks fail. Usually won't raise the vehicle, but have seem them lift the vehicle, but then slowly lower it. If you're under there working, you might not notice it in time. But conceivably it could be a sudden lowering, which was what I was mainly addressing.

On the question, for my DI I put the bottle under the axle, never any problems.
