Drilling for relief tube and gear weldment installation
After some more thought today I decided to drill a 7/16" diameter hole in the lower flange
of the left gear weldment for the relief tube to pass through. The quick disconnect barbed
fittings are for 1/4 inch ID tube, so I figure the OD will be about 3/8 inch. However, since
the tube runs at an angle the hole needs to be slightly larger to be able to pass through.
I drilled a matching hole in the forward lower skin.
With the weldment held in place it looks like the holes don't match up! Eeek!
Not to fear...I actually planned it this way. When you look along the gear socket, the
holes do indeed line up. This is the path the relief tube will take on it's way out the plane.
I spent some time getting the right gear leg installed, then torqued all the bolts on both
gear legs. I had to borrow Tom's torque wrench for the AN4 bolts since mine didn't go to
high enough torque. After getting everything torqued correctly I set about applying torque
seal to all the nuts. These two nuts on each side looked like they were going to be tough
to do, though, since they're at the bottom of the gap between the forward and aft halves of
the center section.
Actually, it wasn't as difficult as I thought it might be. Torque seal applied. How?
Needle nosed pliers to the rescue. :-)
Here are both of the gear weldments installed. I'm really glad I did the fitting of these
weldments way back when the fuselage was in clecos. Most folks have lots of trouble
getting them to fit, but since they had been fit previously, this installation was a snap.
