Task for today was to remove a vac cylinder from a Grampus wagon and refit a newly overhauled one. Once I had the thing disconnected, undone, burnt off the trunnion nuts and on the floor no problem. Putting it back a bit more tricky trying to line up the bolt holes and fitting new bolts, but we got there. Then once I was on the floor on my back under the cylinder refitting the valve and hose, I noticed a slight problem. The valve was on the outer side of the cylinder and the hose would not reach, no problem, got a longer hose. That however was at its limit and would rub on the piston. Strings would need adjusting as well. Questions - Can a cylinder fitted with the valve on the outer side of the cylinder work correctly? Can it be rectified by fitting a longer hose? Or do I need to take the whole cylinder off again, turn it 180 degrees and refit with the valve in the centre of the wagon?
