I think I am a little like Eugene about my skepticism regarding the care previous owner's have taken of their equipment. However I will admit to being REALLY REALLY ANAL about maintenance (old pilot). As an example when I buy a used car or truck I "zero" out all of the critical components and maintenance, inspection and service items by changing all lubricants such as engine, transmission, rear end, transfer case oils, belts, hoses, fluids such as brake, steering, coolant and lubricate, oil and grease all service items, rotate tires, align the front end, etc. Expensive yes but my equipment runs for hundreds of thousands of miles. I create an Excel maintenance sheet for the vehicle and track all of the line items of interest and the ones that have time and/or mileage frequency specifications. When the sheet opens the sheet reads the computer's system date and updates the date dependent cells and then after keying in the current vehicle mileage the mileage dependent cells update. Cell colors change to amber when an item is getting close to being due and to red when and item is due or past due. It is the only way I can keep track and "remember".
So, I am doing a similar "zeroing" out of my Cubs as I get to each (I am doing my first one of three). I believe that if I can keep my stiff joints off the floor, minimize the surprises and number of band-aids and blue language, and keep my Cubs functioning, safe, running, working and in one piece then that is "my self imposed cost of use or of my new hobby". Because hours and time are the initial unit's for the determination of when the component, maintenance, inspection and service item is due I will be installing an hour meter on all of my "new" cub acquisitions as I get to them. All Cubs will have an Excel maintenance sheet tailored to each that will help me keep track of their physical and mechanical health.
OK wake up, take a pill. I am done with my novel. Hey we are trying to work or play in the dirt or snow and be safe and have some fun while at it-right?
