110 Steering pump

110 PU ongoing project have rebuilt front end twice really first started with putting 90 front parts On 110.
Included HD axle of which seemed not to work so moved everything back that was moving three differentials twice.
Now almost have rear end rebuilt.
And looking at steering rods that were frozen now working shape.
But when I went to fit steering arm with steering damper I could not move steering wheel.
This is a steering pump 90 is all manual, does the truck need to be running for this to work or move?
This truck has not moved in? A few years?
Of which I also suspect?

Bit confusing here your pic is of a power steering unit. Above it is the reservoir for the fluid [ black can ] The power steering unit needs to connect to the pump which is mounted on the engine. Engine needs to run to make system work. However if wheels were off the ground it would be possible to move steering wheel by hand only.
The only HD front axle I know of was the Salisbury that was fitted to special duty military Land Rovers.

With the steering arm unattached the steering wheel will not move, besides a little each way then comes to hard stop.
Worked when I drove into shed some years ago none of which was touched.

Is the steering lock on?

You mean that thing with the key?
Had not thought of that, I will need to get battery from other truck test it out.

You don't need to start engine to test the steering lock. Just turn one click and try. You'll feel it disengage

Okay I tried the key & yes since this truck is civilian model it does have a steering lock needs key.

other truck 90 Xmod has no such things as steering lock.
At some point the dash will be apart & will see what that looks like.

thnx.
