I continued working on the main gear today. I removed the right hand axle from the gear leg and carefully marked the location for the cotter pin hole. I did this with the wheel and brake assembled to the axle and marked the location of the notch in the nut on the axle using a sharpie. The hydraulic brake drawings (SNX-L07) indicate that the hole for the cotter pin should be located after assembly. The SNX-L01 drawing shows this hole horizontal with respect to the axle assembly. I drilled the hole for the cotter pin and re-installed the axle stub on the gear leg. Next I greased the wheel bearings and installed the wheels. I left the cotter pins unbent in case I need to take the wheels off to work on the brakes.
