According to my owners manual on the 7.5 Diesel Onan generator the air filter is supposed to be changed every 500 hours, or once a year. I've been blowing mine our with air pressure (from inside towards outwards) every year and replacing it every 3years years with about 150 hours each time. Now with just under 500 hours and 10 years old I'm thinking about replacing it again. It has never been very dirty whether blowing out or replacing, but just wondering how many of you actually replace your air filter every year.
Also, can the engine V-belt be checked very good from underneath without actually removing it? And the manual says to replace it every 5 years or 1000 hours, is this really necessary. My 1991 Honda manual said to replace the engine drive belt every 6 years or 90,000 miles but mine was changed at 73,000 miles after over 15 years and the mechanic had a hard time finding a crack in the old one to show me.
