I have a M739 that has those "sealed" pulleys that squeaked. They pulleys were quite stiff to turn by hand. I had never done any So I decided to "play nice" and take one apart, clean thoroughly and relube with some Phil oil. I put it back on the bike and it was still stiff. Well sheesh. So the other one I decided to just squirt some WD-40 and both sides and work it in, so to speak. That one started spinning freely quite quickly, so I sprayed the other one too and it was now spinning freely. Three cheers for squirting WD-40 directly in the pulleys.... zero cheers for taking them apart and trying to be all "proper" about it.
So try squirting some WD-40 on both inner sides and spin 'em around. On Saturday, August 29, 2020 at 12:55:28 PM UTC-4, Litho wrote: > > Quick question for everyone.
