Now and then, someone asks for specific photos
of the 5623. Unless they fit one of the existing pages, they will
view of the retention tank shows the overflow pipe exiting the side of
the tank near the top, making a right hand bend and heading downwards,
below the tank. This vent serves 2 purposes. Without it, the tank would
pressurize and the airboxes would not drain, just like having the airbox
drain valves shut. And should the tank fill up, there will be a noticeable
trail of oil on the ground. One added benefit is that I can tell if there
is any water appearing in the airboxes without removing the airbox inspection
covers. The large hose seen on top of the tank is the sump drain.
This is the drain arrangement on
the tank. The tank is mounted high enough in the air so I can get a 3 gallon
pail under it when drain time comes but I have to keep an eye on the process
as the tank holds about 12 gallons. The tank is made of 1/4" plate and
is of welded construction.
