TIL checking the discharge line for wear can save your pump in Yuma
Last month I ran a job near Yuma and my cutterhead kept losing pressure around hour six. I checked the usual spots, suction screen, hydraulic fluid, even the relief valve, but nothing looked wrong. Turns out the rubber discharge hose had a slow internal blister that was collapsing under load, and I only caught it by feeling along the line while it ran. A 12 foot section of that hose cost me $340 and a full day of downtime. Now I run my hand over the entire discharge run every morning before start, especially in hot weather. Has anyone else had an internal hose failure that looked fine from the outside?

That kind of hidden failure shows up everywhere once you start looking for it, like a tire with a bubble you can't see until it blows or a phone battery that acts fine until it hits 20 percent. The outside looks great while the inside is quietly going bad, and the only way to catch it early is to check by feel or by habit instead of by eye. Your morning run over the hose is the same thing as squeezing your tires before a long drive, cheap and boring but it saves you a very bad day.
