Time: 8 Hours
Since I have to wait on the canopy project until the backordered parts arrive I decided to move onto the wheels. First up was to an package the parts I needed, which included the cool looking machined blue anodized axles.
With the axels temporarily installed I was able to check for either toe-in or toe-out conditions. That means the tires are both in line with the centerline of the fuselage. I did this by running a fishing line across both axels and checking the spacing between the axels and the line. All was perfect which meant I could move on and don’t need any shims at this time. First up I needed to drill the holes for the wheel pant attachment brackets.
After I drilled the holes I cleaned up the parts and primed them before riveting the nutplates on.
Once apart I prepped the tire and inner tube with talcum powder (baby powder) and coated the inside of the tire and all over the tube. I put in a bunch inside the tire to help the tube move around during installation as well during landing/taking off as the tires get side loads.
I then installed the tube and aligned the valve stem with the red dot on the tire. I inflated the tube to around 25psi just to give it shape and prevent the tube from getting pinched when I put the wheel together.
You can see the tire isn’t set on the bead or put to the edge of the wheel yet. I’ll be able to do that with air pressure. Before I do that I need to finish up the bolts on the wheel but I need to make sure the tube isn’t getting pinched with a small mirror.
I had purchased a bearing greasing tool that I needed to used to push some Aeroshell 22 grease inside the bearings. The idea is you load up the cup with the grease then slide a plunger inside the cup. The plunge has holes in the center area for grease to come up through as the plunger is pressed. There is a top to the plunger that seals the top of the bearing as you push down forcing the grease to go into the bearing and out of all the openings.
I found that it was pretty difficult to push by hand with enough force to squeeze the thick grease. Based on a review I tried putting the greaser sideways in a bench vise which worked like a charm. With the bearings done it was time to install all the parts on the gear legs. First I needed to separate the two brake pads so I could install the brake caliper before the wheel.
The last two bolts get installed but in the opposite direction as they have clearance issues with the wheel pants the plans say. So with the bolts torqued the axels at on for good. I the slide on a wheel spacer and put the wheel on. After the wheel was in place I bolted on the second brake pad.
There is another spacer on the outside of the wheel followed by a large axle nut. This nut get snugged down to the point where the wheel just rotates freely. At that point you drill through existing holes in the nut down through the axel. Once the holes are drilled you put in a large cotter pin to secure the nut. I didn’t drill yet as I want Glenn to look and the amount free spin I have first.
