This morning I went to the hangar and worked
on the oil shutter and radiator damper modification. I started by shortening the top pivot shaft
on the damper door. I also reduced the
length of the arm on the damper control. I then fabricated
a mounting angle for the controls. I
painted the angle black and mounted it below the master switch module under the
instrument shelf.
I also drilled two holes in the firewall next to the brake fluid resivour and installed some grommets for the control cables to pass through. I installed the lower cowl and determined a
path for a section of 3/8” tubing to pass through in the cooling duct. I installed the duct with Adel clamps. I also installed a section of tubing through
the firewall for the radiator shutter control to pass through. I installed the tubing and the control
cables.
I also labeled the control knobs. With the controls pushed in the oil shutter
and radiator damper and both open. By
pulling the control knobs the shutter and damper close. I put some high temp red RVT over the
grommets and controls cables where they penetrate the firewall. I will install the control wire swivel connections
tomorrow if they come in the mail today.
