The Rotax service manual calls for both magnetic plugs to be inspected
during an oil change, but apparently later engines only have one plug. I
mistakenly removed the plug on the bottom of the sump in line with the
bango bolt only to find that it was not magnetic, and has to be replaced
using locktite, which entails a thorough cleaning of mating surfaces -
not easy in situ.
I failed in my attempt to remove the real plug, which is located towards
the bottom port side of the gearbox and is apparently taper plug, and
so at the suggestion of Graham Singleton I have put a small magnet in
the oil reservoir. The magnet came from a magnetic catch, and it
conveniently had a hole which made it simple to bolt to the bottom plate
which holds the gauze filter in the reservoir. Removing the bottom plate
when doing an oil change is no bad thing as all the sludge tends to
collect under this plate. While doing this I decided to drill the bolt
which secures the clamp holding the top of the reservoir, in order to be
able to wire lock it, as I was not impressed by the security of this
bolt.
I hope these comments may be of interest to anyone like me doing their
first twenty five hour check.
