Landing gear O-ring conversion
« on: March 28, 2012, 04:54:42 PM »
If anyone is considering converting the oil seals in their landing gear from the chevron type, to O-rings, you can refer to Burke Bell's drawing.  The thing to keep in mind is that the bore diameter of the bronze gland should be determined by the actual diameter of your individual oleo struts.  I've found quite a lot of difference in O.D. between some old struts and some newly produced ones which actually measure 1.125"  The old ones ranged from 1.119" to 1.123".  The fit of the new struts was too tight for a gland also measuring 1.125".
