Hit 5,000 hours on the old cutterhead pump without a major rebuild, which honestly makes me question all the new 'maintenance schedule' talk.
We ran that thing on the Columbia River project for three years with just basic fluid changes and it never missed a beat, so maybe the book time for a teardown is more of a suggestion than a rule, right?

Five THOUSAND hours? That's absolutely wild for a cutterhead pump. The book time on those is what, half that for a full teardown? Makes you wonder if the schedules are just for the guys who run their gear into the ground. Some of that old iron just had a different build to it.

Yeah, the book time is for worst case stuff. If you're running clean fluid and not beating on it, you can push those hours way out. Just keep an eye on the pressure and temps.

Haha yeah for real, I had an old 4-inch cutterhead pump that I ran for almost 6000 hours before even thinking about a full rebuild. @fisher.mason is right, the factory manuals are super conservative. I think they write those numbers for guys who run sand and water all day without caring. If you keep your fluid clean and don't run it dry, that old iron just keeps going. Maybe it's just me but I'd trust a well-maintained pump over the book numbers any day.
