Opposite steering

[johnik]

long shot but could they have put the ram back together wrong causing it to go in reverse ?

nope , they are just basically a syringe , with either one or two hoses , , single acting has one hose where the needle would be and can only push ,, you need a spring or gravity etc to return it to start position ,,
double acting has a hose at the very top too , so fluid can be put to the other side of the piston to force the rod back to its start place ,, hth

Change the hoses over on the steering wheel pump, probably/usually the same unions...

Changing the ram around won't make a difference.

Looks like a double acting ram same as on our old Cat fork lifts so either pipes swap or turn ram round & leave pipes.
If you decide to reverse ram check for fouling, There are a No of adaptors are you sure that's where they were.
Presume 1 end is on frame not between 2 links

then just swap the pipes.

The fittings will not allow me to swap around,as I said they’re non interchangeable,as in ones several mm larger.
Yes it’s on blocks to allow me access and to operate steering and bleed,no way I can go lock to lock without an airport runway,and it steers opposite wether up or not.

It will if you leave the pipes on the same!

@nickk, is this single or double acting cylinder!

If a double acting see below -

if you can leave the pipes on and swap the ram around do that!

For tom and zzr, if the LH pipe pushes ram To the left, then if you swap ram around, leaving pipes on the same fitting, It will then be that the previously LH pipe will now push to the right.

Leave the ram how it is. You don't ever want the body of the ram to be a moving part - it'll wear the pipes through. There are already marks where the pipes touch the chassis.

Which way the ram pushes makes no odds here. Extending the ram turns one way, retracting turns the other. The only difference is whether the rod moves or the body.

 

[eLuSiVeMiTe]

Yeah. Struggling to see what difference turning the ram will have

Il go with the fittings have been switched during it's refurmb

If has two two way rams it should be piped as below.

only one ram , covered in an earlier post.

 

[Ton-up]

Sorry fellas, I was looking on my phone and was thinking the ram was mounted in the centre and the centre rod went right through and out one side and then out the other side like all our ones at work

Now I'm on my laptop I can that its a single acting cylinder and one ends mounted to the chassis!

In the 18 years of working on fork lifts, I've done.

I've never seen the cylinder part of a steering ram connected to the stub axle, the cylinder is always the fixed end.

ie: to the axle casting.

Double acting cylinders are the normal type used.

It's not one of those assist rams is it ? The sort that use a conventional steering box/links and the ram attached senses movement and assists.

if that was the case there would e a shaft running into it , like on avling barfords , but from the pic , just two hoses .

I had one on machine that sensed the push/pull from one end. It went squiffy and when the engine was revved it would turn left on its own.

I’ve since swapped the hoses around at the steering wheel (the valve block that I replaced about 8 years ago). Couldn’t start it to try as all the ignition switch wires fell off and I haven’t a clue where they go,my guesses going by wear marks,were no help.

steering should now be fine ...
as for the wires
If you had a Duck it would drown ,,,, lol ,, thats not my department some one else will have to help you out on that one

Check out Clark c500 from the 80's the piston is anchored and the cylinder and valve moves. Crazy but true

A firm I worked for Purchased 3 Seddon Atkinson 180 Borders.

We fitted PAS systems that used the ram/valve units to replace the drag link between the steering box drop arm and stub axle arm.

The turning left syndrome is a weak spring usually in the control valve...

 

[nickk]

Corrected now,I swapped the hoses around at the wheel,mechanic confessed he may have got them muddled .
