Wheels
Conventional wisdom....
1. When installing a wheel, always assume it is a weapon.
2. Always deflate said tire during assembly and dis-assy.
3. Red dot on tire goes where the valve stem exits the rim.
4. Use baby powder to dust the tube prior to placing tube in tire.
5. Always have someone else around to be able to call for help or render assistance.
6. Never just swap bearings without swapping the race as well.
7. If anything catches your nails on the race, swap the race and the bearings.
8. Muffler tubing from auto store works great for pressing the race out/in with the assistance of an oven and a freezer.
9. You pack the bearings and when you place them in the wheel assy, put some grease on top by hand prior to placing seals on it.
10. The bearing is torqued down to seat the bearing in the race, then it is backed off and re tightened to place everything back together. If you just torque it down, maybe it could mis-align slightly.
11. During tightening back down, you want the wheel to spin about 1.5 times and come to a complete stop. Then cotter key it.
12. Always treat it like a weapon. If you don't belive me, look up over inflating wheels on YouTube and watch them blow the safety cage apart.
13. Feel free to use new hardware when you reassy the wheels. Cheap insurance for sure. If you see discoloration, time to swap out your bearings.
14. Always follow the appropriate instructions and don't be afraid to ask questions.
15. If you have toe-in/out problems, put wax paper on the floor and roll over it to see what your wheels are doing.
16. If using multi-leg jacks, place a piece of paper under each leg during jacking to see if the jack is tilting to avoid your aircraft falling off the jacks.
17. Close the hangar doors as much as possible when you are jacking an aircraft.
18. If you are having shimmy problems, try lowering the tire pressure.
19. Never conect a high pressure bottle to your tire. Always have a low pressure regulator on a bottle.
20.Wear appropriate protection for what might happen.
Treat it like a loaded weapon. People have died doing this.
