Did BMW put sealed bearings in the swing arm on '88 - '93 R's?
My '93 RT had the same bearings as my R90s.
Pop the caps off the swingarm access. If there's a small hole, then use a tip insert on your grease gun to shoot some in.
Good time to check your swingarm clearances (frame to swingarm should be equal on both sides), as well as loosen and re-do the torque on the bearings. (Pre-load to 15 ft. lbs. Loosen and set to 7-9 ft. lbs.)
RPGR90s
What a conundrum, I'm pretty sure RPGR90s had his '93 since new and did all the wrenching on it. And 88bmwjeff brings out a number of probable reasons why he believes the swing arm bearings are sealed on my '93 RS and not repackable as with older models. So what's a guy to do? Here's a couple of early morning pictures, both left and right on where I plan to inject some moly to see what happens...just as soon as I buy the grease gun and Moly. However, first things first, so off for chemo then back to the priority of the day "problem". Thanks for all the input, this new to me bike has been great as it takes up time in a fun and sometimes mysterious way. See pictures in next post...
Is moly required or will moly do? Supposed if sealed it won’t matter.
