Hello,

 

Rotax 914 SN 9575296. I'm going over all the SB's and I'm trying to make sure I have them all done.

Any way to tell from the Manufacture date if these have all been carried out?

It would appear I may need to do the carb circlip and the floats (at least check). Or are the floats supposed to be replaced/inspected every 25 hours? Thank you.

    The Engine Logbook should tell you which SBs have been carried out. 

    Your engine 9575296 (914UL) was produced 02-Oct-2015, so you should check all bulletins issued since then. You can search by engine model and then select date range 10/2015 to 02/2021 on our SERVICE BULLETINS Page - that will provide you a list of all 'potentially applicable' documents. ( check the details of each to verify if they actually apply to your particular configuration)

    Thank you, that's a lot of info.

     

    Would this suffice & show what needs specific to the engine SN?

    You won't have to worry about the change of temperature measurement from cylinder head to coolant.  That was a big change in design, and it looks like your engine was made after that changeover.  You'll definitely want to change those carb circlips, and to weigh your carb floats (many of the latter have needed to be replaced).

    Awesome! Thank you!
