I worked on my landing gear though it was so simple as most of the work is already done.
I started by bolting the axles to the gear.
Next I put the 1st wheel collar on the axle leaving just enough space to be able to slide the wheel pant on. I also put the set screw poing down.
Then I put the wheels on. The wheel fit really well. not to tight or to loose. of course next was the outer wheel collar and once again with the set screw pointing down for easy access.
It was only a matter of bolting the wheel pants on an the job is done
