Convert 914UL3 to 914UL2

Hi friends,

We have a 914UL3 engine with a variable pitch propeller. Planning to fit it with a fixed pitch propeller i.e convert 914UL-3 to UL-2. Is there any retrofit kit / Service instruction available from Rotax, in this regard? Couldn’t find anything in the IPC.

We referred Rotax manuals and gathered what we may have to do:

               1. Remove Governor from the mounting location, blank crankcase location.       

               2. Remove oil feed line to propeller shaft and blank off the opening.

               3. Not sure about propeller Shaft

     -Is it possible to unplug and reuse? or need to buy a new one?

     Existing Part No is 837284.

4. Drive gear/ RGB can remain as is?

5. Also any need to change/modify TCU?

It would be great to receive all possible guidance.

Has there been any prior discussion on the subject in this forum?

Best regards,

Ray
