List:

   

  Anybody know a trick for removing the 3 hex screws that hold the rubber donut on the flywheel? Those puppies are loctited and torqued pretty good and the whole crank wants to turn with them. Rotax probably has a $200 tool for the job that I'd rather not buy for occasional use.

Marco,

Hopefully, you don't have thre rubber donut removed yet.  There is a trick to 

getting it off so that is is easily reinstallable.

First, get a large hose clamp that goes around the outside of the donut.

Tighten the clamp around the circumference of the donut.  This will stop it 

from expanding when the bolts are removed.  It will lso make sure it keeps it 

shape so the bolt holes line up when you reassemble.  Don't remove the clamp 

until the donut has been re-installed.



Second, the proper was to lock the crank is by inserting a ROTAX locking pin 

into the impulse port on the engine (this is the $200.00 tool that costs 

$2.97).  One of these pins should have been in the Rotax tool kit.  You will 

have to insert the pin into the impulse port and slowly turn the engine over 

while lightly pushing on the pin.. There is a hole in the crankshaft that the 

pin will slip into..This will lock the crankshaft in place.  Do not use a 

drill bit or any brittle metal rod.  If it snaps you are looking at an engine 

dissasembly to get the broken part out.  On a 582 thats a 10 hour job as the 

engine usually has to be completely broken down.

There is another tool that bolts onto the flywheel that wil also lock the 

flywheel.  It's quite a bit more money, but its's also used to pull the 

flywheel.



Once you have the engine locked up you can easily remove the allen bolts.

You should note the position of the washers under the bolts.  One of the flat 

sides should face the outer edge of the donut and the other flat should face 

towards the center of the donut.  This positioning is important so that the 

washer does not contact the bodt of the gear drive.



The allen bolts on the C & E drive rubber donuts are fairly shallow.  You will 

need a good quality allen wrench firmly pressed into the bolts in order to 

safely ermove them. Get a new wrench if yours is any way sloppy.



Hope this helps
