Fit the fuel gauges
Remove the masking tape from over the fuel gauge boss in the wing root and clean the area.
Test fit each fuel gauge – feed the float unit into the wing tank
and hold the gauge in place with 2 screws. Check the empty
indication – the needle should sit slightly below the “E” or
“Empty” mark as shown in the photo at top right.
If it does not then the gauge will need to be adjusted.
The gauge needle is driven by a magnet that is turned by the
action of a float that sits inside the fuel tank. The gauge can be
disassembled by pulling the black nylon float drive out of the
aluminium gauge body and the magnet can be twisted slightly
by hand. See the photos below for detail of the gauge unit.
The gauge can then be reassembled and rechecked (and readjusted if necessary) until it reads
correctly.
The nylon drive unit barrel should be a firm fit into the gauge
body: if the fit is not entirely to your satisfaction then a smear of
Loctite 577
Sealant
should be applied to the barrel.
When the gauges are fitted each of the 4 retaining screws and
the top and bottom gauge face screws should have a small drop
of Loctite 242
Threadlocker
applied before fitting.
Carefully bend the electrical spade terminals out so that they are
parallel to the face of the gauge as shown circled at right.
