I'm looking at the rotax oil purging procedure and also the video at rotax-owner.com. Three questions:
1. It says to replace the valve cover o-rings after performing the initial purge procedure and checking that the valve lifters are properly purged. This is a $67 set of gaskets! Is anyone doing this?
2. The oil drain at the bottom of the oil tank has a crush washer. It is a $1.71 part to be replaced each change. The Rotax parts manual shows this as P/N 250010, a 12x18 (mm I assume).
If 12x18 means IDxOD, then it is 0.47" ID and 0.71 OD. That is a ring width of about 1/4 inch - wider than the AN ones linked below which are 1/8 inch.
Anyone know the AN900-XX designation for this so I can get it at AC Spruce? (AN-900-8 is 1/2 inch ID) If anyone has an uninstalled extra and can measure the ID and OD, I can figure it out at http://www.aircraftspruce.com/catalog/eppages/an900.php
3. Has anyone put on an oil quick drain? This one maybe?
