Pedal Major Service (PD-6800)

I just decided to do a major service for the Ultegra pedals (PD-6800). So this will be a complete tear down of each pedal =D

These tools are needed:

  • Bike stand
  • 7mm spanner
  • 10mm spanner
  • 17mm spanner
  • Torque Wrench
  • Grease
  • Anti-Seize
  • Towel
  • Degreaser

No warranty in ANY case of damage!

First of all is to dismount the pedal. After that head for the pedal body to free the axle and bearings. To open up the alignment just unscrew the two nuts. Then the bearing-balls will be freed.

Note: Keep in mind the alignment as well as the direction of the gasket/seal. The nuts are also bonded to the direction (left/right handed thread).

I cleaned up everything with a degreaser so every thing is in “like new” condition. I also check the wearing… nothing all balls are good as well as the axle. So it is time for re-assembly. First for that is to grease up the bearing groves so the balls will stick in its place (total 1,5g). This is sometime tricky but nothing special.

Final step before the pedal body will be installed is the bearing alignment/clearance.

Everything done? So put the pedal body back on the axle (10NM) and go for the final assembly. The Torque on the crank arm is 35-55NM for each pedal.

Note: Right pedal is right threaded, left pedal is left threaded! And do not forget the anti seize!
