Re: New owner of Hymac 580B

Thanks very much for the picture, i will compare this image to my pump and see :)
Yes i fitted cable control. I would estimate the cost for the whole rebuild to around 335£

Re: New owner of Hymac 580B

Finally the winter is over, the beautiful spring is here, i love it :) As i said before i wanted to rebuild the sliding door and make it to the more modern model with hinges instead. With the new controls it would also give some valuable extra space in the cab. Here comes some photos of the rebuild:...

Time for an update. Replacing the springs in the valves was a pretty tight job to do. Not much of a space to work on. 20180308_144747.jpg 20180308_144805.jpg 20180308_143753.jpg Connecting the wires to the valves 20180318_154737.jpg 20180318_173158.jpg Brackets for the joysticks 20180321_103905.jpg ...
