Alpha one gimbal ring bearing replacement

[Jwall26]

I’m replacing the bearing in my gimbal ring. I’ve got it pressed in but not sure how far to go there is a seal and spacer that go on bottom. I don’t know it the spacer is supposed to set flush with the bottom or what?

Post a pic so we can see the placement
Is this a Gen 1, 2 or MC?
There is a rear seal but what spacer are you talking about, the tolerance ring maybe?

The seal looks good, looks like its just barely below the ring surface. The spacer is for the most part a washer (flat bushing) to keep the ring spaced from the lower housing

MC makes a special tool to press in bearing. If female part is clean, it should bottom out. Make sure grease cavity lines up correctly with bearing and housing. Some bearings are sealed, and some are not sealed.

No grease cavity on lower pivot pin

Didn’t seem to bottom out. Grease hole aligned. I have a roller bearing didn’t see a sealed option.
