Installing your crank arms and pedals, these are the all-time practices and tips to avert mistakes:

Crank Arms:

  • Be sure to orient the crank artillery in opposite directions (180 degrees autonomously) when installing.
  • Tighten the crank arm bolts to 39nm.
  • If they are installed at the incorrect orientation to each other, you lot will demand a creepo puller tool to remove 1, rotate information technology, and reinstall it. Please see the video at the lesser of this page, it illustrates how to use it.

Pedals:

  • Be certain the left crank arm is on the left with the left pedal and the correct creepo arm is on the right with the right pedal.
  • Thread the pedals in past mitt to start, carefully, yous should non accept to forcefulness them. Once they are threaded in properly to start and you are sure they are properly aligned, you can use a wrench with a thin caput (see movie below) to finish tightening them. Failure to properly thread the pedal into the crank arm will cause cross threading to the creepo arm.
  • While bike mechanics often use this manner shown below, it does not require one this thin. Whatsoever wrench no wider than the flats shown here will work properly:
  • If you lot employ a wrench that is too wide, it volition be in the way equally you lot tighten the pedal. This will crusade it to not be fully tightened which can so damage the threads in the crank arm once ridden.

Unfortunately, this is a common assembly error and if your pedal has come off or at that place is another issue, it is probable due to one of these mutual mistakes.

Often if installed improperly it results in the crank arm being stripped, at that point the creepo arm will need to exist replaced. Typically, the pedals are ok, because they take steel threads, where as the crank arm is aluminum and the threads are softer and frequently damaged beyond repair. Depending on the bike & which side is stripped, you may be able to replace but one. For non-drive side cranks (50) You can order unmarried replacements (make certain information technology matches your other crank, diamond style or foursquare shown beneath). The drive side (R)/ Side with chainring, by and large come in a gear up of both Left + Right cranks.

If replacing left or correct crank, PLEASE VERIFY, is yours Foursquare or DIAMOND. The new office needs to be the same as the one y'all take. Or alternatively, both tin can be replaced, but tin can be more expensive and you will need a crank puller tool (about $x.00).
