hydro oil started coming at the back right, I traced the problem to a connection between a hose and a steel pipe. Which is in fact the bucket crown action hoses, from where it leaves the arm into the rear frame it appears to go into a short hose running down into a steel pipe, both of which cant be got at due to plate steel on both sides. Have you ever had to take these out ? I assume you have to undo steel pipes at valve bank and draw hoses and pipes out towards the bottom, even this looks like a mission just to get any movement out of the steel pipes as they do 3 x 90 degrees turns. I thought about cutting a hole in plate steel where the 5 is on vertical stickers of 753 Or do you know of any tricks or helpful hits on how to remove. cheers des
