Well its that time to change the leaky seal on my 650 Outlander. I have read a bunch of posts regarding this I just have a couple questions. What parts need to be ordered to complete the job? Looks like I can order the oil seal and O ring but there looks like a sleeve that goes with the O Ring that can not be ordered. It looks similar to the wear ring that is replaced when you do the seal on the Differentials. Is the sleeve necessary or do you guys just replace the oil seal and O ring? One last thing how are you guys getting the oil seal out?
