I want to emphasize the comments about working through the checklist. Why? I'm working through the front end on my '51 and got to the part about draining the oil in the steering gear. I popped the drain plug loose using the Shade Tree Plug Removal Tool and waited for the old nasty oil to drain into a bucket. And waited and waited.
There was no oil in the steering gear housing. Instead there was 50 year old sludge mixed with a little water. If I had been picking and choosing which things to check, the steering gear would have been low on the list. The steering was not bad, no binding, and after all who would run a tractor and not keep the vital fluids topped up?
Well, I guess that is the point. When I was learning to fly, I was told over and over that you only KNOW the condition of the aircraft if you have checked it yourself. Relying on the best intentions of a crew chief or previous owner is a one way ticket. Admittedly, you are not likely to die if you miss something on your Cub. Although just about everything on a Cub is part of a mission-critical system. So why take the chance of killing your Cub if you overlook an item.
This is not really a rant, rather a statement of how I approach machinery. Your approach may be more casual then mine, and I wish you all the Joy of your Cub.
