Just hit 10,000 hours on our old cutterhead dredge and the numbers shocked me

We've been running the same machine on a channel project in Mobile Bay, and the maintenance logs showed we spent 15% less on wear parts this year than the last. Some guys say you should rebuild or replace before hitting that mark, but our foreman swears the old girl is just broken in. What's your take on pushing a dredge past major hour milestones?

Wow, 15% less on wear parts is a huge deal. That data seems to back up your foreman's "broken in" idea pretty solidly. What's the actual condition of the critical components like the main bearings or the cutter drive? I guess my big question is, are you tracking anything besides cost, like downtime hours or production rates, to see if the old girl is truly still efficient or just cheap to patch up?

You said "cheap to patch up" but that's not quite it. The cost savings come from known failure points and bulk buying, not from skipping needed fixes. We track downtime religiously. Last quarter, Machine 7 had 12% less unplanned downtime than the newer Model 12s. Production rate per shift is within 3%. The data shows it's reliable, not just a money pit.
