That's good info, and makes a lot of sense as many industrial pumps and equipment use hours as the maintenance metric.

Changes at 60k feels a bit early for proactive replacement, but if you really don't want to be stranded it could be worth it. If I make it to 90-100k without failure, it will definitely get replaced.
