Firewall forward systems continued…

Oil cooler tray assembly ready for installation.

Yep, you’re right – there’s no way to put a wrench, socket, or other tightening implement on that bolt head without removing the lowest Camloc flange. I tried everything that came to mind, but eventually had to do just that.

Camloc flange removed, bolt tightened, and flange about to be replaced.

Oil cooler tray installed.

I just set the oil cooler in place to check that its flange holes lined up with the tray nutplates.

Oil cooler and inlet assembly installed.

Oil cooler lines installed along with oil pressure line.

Oil cooler lines installed along with oil pressure line.

The oil pressure line needs to have its Adel clamp replaced (a ‘tomorrow’ task!) due to the firesleeved Aircraft Specialty line being too large, diameter-wise, for the original clamp.

Looking down at the two oil cooler hose connections.

Firewall forward systems progress

Two of three duct tee SCAT hose hookups in place.

Final fuel line (from firewall to engine-driven pump) connected!

Last of the duct tee SCAT hose hookups in place. The large Adel clamp suspending the hose from the engine mount is another of those cantilevered clamp arrangements and its screw/washer/nut were a first-class bitch to get started, even with all of the usual “tricks” in play.

Various oil cooler inlet and support components being primed.

Cooler inlet assembly riveted together.

Cooler inlet assembly tape masked for application of RTV.

Oil cooler fittings installed.

Oil cooler ‘P’ seals installed.
