Maintenance schedule check/change intervals of major components list?
I am looking for a general list of recommended check/change preventative maintenance intervals based on mileage of major components such as bull gears, oil pumps, coolant change, fuel lines, transmission/gear oil, etc. I know there is varying opinions on when to check some, but I believe having a list available of generally accepted time frame to have these major components checked/replaced would be helpful to everyone in avoiding very costly damage to engine, expenses and downtime. I have heard stories of the bull gear alone just putting people right out of business before they know what even happened and learned it after the fact. This list could help out many of us survive these possible scenarios before they occur unknowingly.
Is this a good question?
