Hi Folks,



On The lower cowling i have is an outline, which seems to be intended to connect to the Rotax cooling air shroud. Is that correct, and what is the best method to follow to make a nice join between the two?



Kind Regards,



Jos Okhuijsen

Hi Jos,

 The scribe line you can see is where you cut a hole.... there is a splash  molding which sits on the outside of the cowl to lay up on the inside, which  makes a ''funnel shape scoop'' to direct air into the shroud inlet....this comes  [ or should] as part of the 912S firewall forward kit. [ If your kit was packed  by Maureen, at EMIL, chances are it is missing ?] I think I have a spare if you  need one?

 912 and 914 FWF kits do not have them as standard.

 Cheers,

 Nev.

JOs

make a tube same diameter as the shroud inlet tube and bond that to the 

cowling, then cut off the ends of the two tubes so that they mate but 

don't touch. The cut line needs to be at right angles to the plane of 

the vibration, so I guess in the same plane as the engine mount rubber 

faces.

Long time since I saw one of these so get a second opinion

Hi! Jos

I've "just been there".

Europa say that the imprinted lines on the Cowl front are only for the

"hood" to cool the barrels on the 912S. However I am having a hood on my

914 when it comes.( I've had 7 years of keeping an engine cool thanks,

this time I will enjoy blanking off if it is over cooled !)

 The best way (if you are having a hood ) is to cut out on the line and

use a specially produced mask, which is a mold. You give it two coats of

release agent and attach it with double sided tape then additional tape

over the mold to the outside of the cowl. With it fixed in place turn

over the cowl and put four layers of bid on the inside of the cowl by

25mm and mask, having prepared the area around by scuff sanding ready to

lay up in the normal manner. Cover with peel ply.

Allow to cure, remove all the outer tape, and prise off the mask.

If you have done a good job you will need a minimal amount of filling to

blend it all into the cowl and have a newly produced entrance for

cooling air to pass into the hood entrance.

Roger Cullum has a mold for this purpose which I have returned to him.

However I'm sure that Europa are able to provide it as an off the shelf

item.

If you contact him and he agrees to lend it to you I could probably

bring it to Gallivare over Christmas and bring it back if you had it

completed by the time I leave.

Thanks friends,

For all the quick and good advice. 



It's all in the 912 manual, not in the 914's. Don't understand why the factory assumes the shroud is not a 914 option. I called Roger this morning and the moulding is on it's way. 



Kind regards,
