how much is 1 ton of pressure?

[matt 2LT]

i need to push some bushes into a rear subframe on my E46.

now im trying to find a suitable press to buy, for as cheap as possible.

so would something like this, have enough force, to push them in.

I would of thought you would be hanging off that thing to get any pressure behind it but I may be wrong. Could a local garage or engineer do it for you if you could get the suspension component to them?

IIRC a ton is a force, not a pressure, but 1 ton is equivalent to 2000 lbs. Hope that helps

Would it have enough force maybe

Would you be able to get it into position No chance


You need to learn how to be clever with some bits of pipe and some sockets and you can pull the bushes into place.

[anonymous-user]

your question doesn't make sense. 1 ton is a mass. pressure is mass per unit area

[Swarley]

Try using your jack. Put it between your jack and something heavy, eg another car.



Oh and watch your fingers!

Try one of these wedged against something solid.

i take it thats a no then.

i will be back to the rod and nut method then.

the problem is the bushes hang over about 1/4 inch, so im going to have to try something clever to get it into the correct position.


and ive tried all the local garages and they are either not interested/want £10-£15 for each bush (there are 7) or say there press is not suitable.

Not to be too pedantic but pressure is a force (or weight, but not mass) per unit area.

hmm i like your thinking, if i could find something very heavy i could wedge ontop of the subframe i think that might just work.

You can get something similar with a frame for not too much money IIRC, we had a hydraulic press at sea which was 6t and was basically a bottle jack on a steel framework.

Like this

Clarke do them I think.

Go to your local fabrication place and get them to chop you off a inch long piece of pipe just bigger then the bush put a strongback over it and a piece of stud bar, correct sized socket and the jobs a good one

[T89 Callan]

Pffft, get a couple of hammers and some drifts. It's not difficult.

i think this is what i will try now, quick question though.

with the bush, do i wan't to be putting the pressure on the metal centre part (that the bolt goes through), or the entire bush.

as i don't wan't to damage the bushes.

[Doofus]

I use a hub puller. Take it to bits, replace the spacer arms with steel discs, and use a long extension on a spanner to do it up, squeezing the bush into place.

force is a lot more complicated than a unit of mass too... the amount of effort required to exert a given constant acceleration to an object of given weight

[Political Pain]

From memory.

1 metric tonne/force is 9800 [and something] Newton [1000/0.2205]

Hopefuly you will have a guide to the force needed to do what you want expressed in Newton.

By the way newton is shown as 'n' and kilonewton [a 1000 Newton] as 'kn'

Hope that is of some help.

[Snoop Bagg]

You just need to go to a local engineers or garage and ask them if they've an Iron Man press you can borrow for ten minutes or if they'll do it for you.

I'd be reluctant to shell out money on something that looks like an "El-Knucklerashio" special!

Or could even be 2240 lbs.

[The Wookie]

1000kg weight is 9,810 N of force

Over 5 square centimeters (guessed area of a subframe bush) that's 3.924 N/mm^2

HTH.
