I like to check my “hibernating” attachments once in a while to make sure that everything is as it should be. I noticed recently that under the right side (looking from the back side...non-sprocket side) that I’m starting to leak grease out of the seal. I believe the part is LVU14903 and is fairly inexpensive, but I’m not sure how I should proceed to fix this. Looks easy enough (4-6 bolts) to remove, but I’m concerned about proper bracing so that the rotor shaft doesn’t get jammed and do further damage (bearings).

Anyone replace one of these before and have any helpful suggestions? Or even torque specs would be helpful.
