Workshop: How to maintain Crank Brothers pedals

Eggbeater, Mallet and Co. are known for their excellent function, but not for the durability of their bearings. With the rebuild kit, you can maintain the Crank Brothers pedals yourself.

Crank Brothers Mallet DH in detail Completely disassembled, you can easily recognise the individual parts of the pedal and the order in which they belong on the axle and in the frame. Needle bearings (or plain bearings) are on the inside, the ball bearings are on the outside of the pedal.

Dismantling and removing the bearings

Pedal service workshop: Here the cover cap is being carefully removed.

You can now use a small ratchet and a figure-of-eight nut to unscrew the lock nut used to secure the axle. To do this, hold the pedal body and the spindle with your free hand.

The pedal axle can now simply be pulled out downwards. Remove the old sealing ring and replace it with a new seal. Then remove the old lubricant from the pedal axle.

For Candy, Mallet and 50/50 pedals, you now need to unscrew the pedal body. To do this, clamp the pedal body in the vice and remove the locking screws using a 25mm Torx.

Fitting the Crank Brothers pedal

First push the new seal onto the pedal axle. The thin side must face away from the thread. Then apply some fresh lubricant to the axle.

Grease the bearing seats and press the new bearings into their seats. Ball bearings on the outside, needle bearings on the inside. When hammering in the bearings, ensure that they are seated straight and avoid tilting the bearings.

The new O-rings are inserted into the pedal cage from the inside. Here too, a new O-ring is placed on the inside and outside. This usually slips into the correct position by itself.

Insert guide bushes The new guide bushes are inserted via the O-ring. Press in the wider bushing on the inside. The narrow bushing belongs on the side of the ball bearing, i.e. on the outside.

Put the wing spindle back in its place between the two halves of the frame. Here too, the side with the wider pin belongs on the inside of the pedal, where the needle bearing is also located.
