11.2 Oil cooling
Note that the engine may contain some oil, be prepared for this when removing caps
etc. Ensure that all oil hoses are properly rated for use within an engine compartment
if not using the hose supplied by Rotax / Flylight.
a) Fix the oil tank mounting brackets on the firewall with 4mm aluminium rivets.
Pilot holes are pre drilled in the firewall for this. Then fix the oil tank to the
brackets using the two large diameter ‘jubilee’ type clips.
There are two rows
of holes running laterally across the firewall at the top and bottom of the
brackets. These can be used to fix 2 strips of L section to stiffen the firewall.
The Uk firewall spec is thicker than the prototype so these are not necessary,
but are supplied in the kit
– your choice!

b)
The oil cooler ‘piggybacks’ behind the water radiator, and attaches to it with
three brackets. The water radiator itself fixes to the cowling with 4 brackets
attached to the 4 mounting lugs on the radiator. The oil cooler brackets fit
outside of these.
Loosely fit the attachment brackets to the Water Radiator. The right angle
brackets fit on the top and the acute angle brackets the bottom. Lay the oil
cooler in position over the water radiator. Space it away from the water
radiator by 6-8mm at its lower edge and 2-3mm at its upper edge. using
cardboard or similar. Align so both lower edges are level, and with right hand
edge 65mm from side tank on water radiator.
