2009 550 H1 - Changing Front U Joint
I am in the process of changing the front U-Joint. I hammered it apart in place using an air hammer. In the process of doing this, a small metallic disk and spring fell to the ground. It came from inside the front yoke (not the yoke on the engine, but the opposite one). I think it is used to seal the shaft so fluid doesn't travel up it. I've attached a picture. That yoke is splined and can slide on a splined shaft. It's not what a parts diagram for this quad shows.
Has anyone else had this fall out? Do you have suggestions on how to get it to stay in place? Perhaps silicone it in place and try and "stake it" with chisel so it sits there? Its a terribly awkward place to work as this is still all in the ATV. I can't imagine why it would need the spring. The spring is working against me.
I assume the differential has seals, so the only purpose of this disk would be to keep the splines free of crud (correct)?
Thank you in advance for the help!
