Hi Rowland,
I removed my Vacuum Pump for a glass screen Instrument Panel last year.
What I did and as you say,
"Add another little piece of aluminium plate thick enough to allow the nuts
to be done up."
I sealed it with a gasket sealant and it covered the Vacuum Drive slot.
Cheers,
Tim

Subject: Europa-List: rotax vacuum pump query
I disposed of my vacuum instruments before I got around to installing them,
and have also sold the vacuum pump before I ever installed it.
I have now got my engine out of the dark box where its been hiding and hung
it on the Europa (just for a trial fit to sort out wire and cable runs etc -
havent got the firewall sorted out yet). Now that I can get a good look at
it, I see theres a spacer plate on the vacuum pump pad - see pictures:

However, as you can see in the 2nd picture the nuts that hold it dont screw
onto the studs far enough to secure the spacer before they become
threadbound, so the spacer will be rattling around and the nuts wont be
secured. So, what should I do? Add another little piece of aluminium plate
thick enough to allow the nuts to be done up? Remove the spacer, nuts and
spring washers leaving the studs empty and the drive splines exposed (doesnt
sound quite right!)?
It appears from the Rotax illustrated parts catalogue that there is a plug
which fits inside the gearbox aperture when the vacuum pump drive is not
fitted, but obviously Id have to do quite a bit of dismantling to use that.
in friendship
