I have a shimano FC-5603 i.e. 105 triple 30 speed hollowtech crank. At 1k ks it started to tick at 1 o'clock when pedalling standing, the lbs pulled it apart, regreased, tightened, & put it back together. Problem solved.
Since then I've added 6k ks, & again I have a similar tick which was intermittent to begin with but is now consistently occurring when pedalling standing. This persistent tick occurs on both sides around 4 or 5 o'clock which is when I start to rock the bike back the other way.
Lbs stripped it down, regreased again, but this attempt failed on the second hill. Pedals have been swapped, greased & tightened. Bottle cages removed & frame welds checked. When it starts I sit down & the ticking stops with the load off the pedals. Have checked left crank arm bolts, chainring bolts, derailleur clearance, and headset play. Creaking is also apparent by putting sideway weight on the pedal when off the bike.
Lbs is suggesting maybe to reface the BB shell. I'm suggesting maybe some locktite type compound as well on the cup threads.
Do this type of BB create more problems than older style BB?
One guy from "over there" has suggested thread tape solved his ticking BB. Any thoughts????
