The Kubota genset in our 2001 has 4,000 hours as it was a NASCAR rig. That's where it got the hours. The manufacturer PowerTech calls the it a 10,000 hour unit but says it'll go longer with proper maintenance. I've friends using the Kubota engine way beyond 10,000 hours. As RVers, we'll never wear it out, adding about 50 hours each year which includes a one hour pre-arrival cool down of the coach in the summer. Using synthetic oil, replaced the radiator's core this year as it was running hot. Good to know of the Grainger ball bearing replacement fan assembly.
