 Posted: Sat Apr 04, 2015 1:34 pm Post subject: Ring mount to subframe question |
 |
|
I am mounting the rotax ring mount to the engine mounting frame using the M10x110 hex head bolts.
The issue is that the M10 bolts have quite a lot of slop in the rotax ring mount, my guess is that the rotax ring mount holes are about 1/2 to 1 mm larger than the bolts.
Is this normal?
The bolts fit perfectly in the Europa engine mounting frame.
thanks
Will

Yup....the rotax ring mount has an 11mm hole and the engine mounting frame is 10mm.
Can anyone help?

Gidday Will,
Have you inserted the short steel reinforcements in the fuselage engine frame, because if you have the wall thickness has now increased dramatically, and the attachment forces now are also shared by the bolts holding them in situ, as I vaguely recall. I'd be surprised if you couldn't open them out.
Regards

Thanks
Sadly thats not the problem...its the rotax supplied ring mount (suspension frame in rotax parlance) which has 11mm holes and should have 10mm holes...
I thinking I got the wrong part number...maybe there are two different frames...

Hi Will,
That is correct, the holes in the Rotax ring mount are 11mm, 10mm in the Europa mount, and 10mm bolts......... not clever ? I put a thin 10mm steel washer between the Europa mount and the Rotax ring mount, prevents the ring mount from getting chafed. Put grease or thick oil on the bolt shank, they are not plated ?
Cheers,
Nev.

Just for the general information of the group I spoke to Bud yesterday on the subject.
I measured everything again and definitely we have 10mm bolts going though a 11mm hole on the rotax ring mount (suspension frame).
He said that it's OK per design to put the 10MM bolt into the 11mm hole on the ring mount and he has 10 year old aircraft with no signs of fretting to prove it.
I guess it goes against every instinct - or at least my instincts - but there it is.
