Two weeks ago, a gentle ride around Derwent Water in the Peek District almost never happened as one of my Clipless Pedals By the infamous Crank Brothers exploded.
The bike ride was saved by a £1 pedal from the bike shop there. The blokie there said that I would notice the difference, but luckily I had no plans on clipping in that weekend and rode with my trusty Converse All Stars.
Back to the Mallet rebuild.
I bought a rebuild kit from Chain Reaction cycles. I chose them over Wiggle as they had a mallet specific rebuild kit rather than a ‘Egg Beater’ kit. Who knows.
First hurdle was to remove the dust cap. As these were second hand pedals, the dustcap had already been attacked and I couldn’t get any purchase with a a large flat head screwdriver. I decided to drill most of it out and cut the remainder of the dustcap wall with a scalpel.
Note to self, Dustcap, 14mm with 0.5mm pitch thread.
Now the dustcap was gone, I could undo the 5mm Nyloc holding the shaft on the pedal to release the shaft. From here, I could see that the problem was that the bearing had disintegrated. The inner race was stuck fast on the shaft and the outer race was stuck fast in the pedal.
The inner race came out broke apart with a set of mole grips.
To remove the outer race, I was going to Dremel the hardened steel outer race, but instead had a moment of clarity. The outer shaft which the clipless mechanism is attached, is perfect to knock the outer race out from the opposite direction.
It just happens that two M6 Cap Head Screws are perfect for this job, as the head is 10mm in diameter. Just right to get passed the 11mm housing and 9mm through shaft! Just make sure you don’t go too far, otherwise you’ll have to rebuild the whol clipless mechanism, but if you just go far enough to push the bearing out pass the dustcap threads, all you need to do is turn the pedal back over and gently tap until shaft is back in position.
The rebuild kit comes with new bearings, bushes, seals, nylocs and dustcaps for two pedals. for £12, not as good as a £1 pedal, but better than throwing away £80 pedals.
