Servicing the Acros A-FLAT SL Pedals

Spread the love

I recently noticed a huge amount of drag while pedaling my bike through the woods. At first I thought badly adjusted brakes were the cause for it. But a closer inspection showed, that both pedals hardly moved at all. Relieved that it was not bad shape that lead to the slow ascends, I unscrewed the pedals for closer inspection.

Servicing them was pretty easy. With the proper tools it takes about 15 minutes to service them both.
An aluminum end cap protects the axle assembly. You start with unscrewing the end cap with a 6mm Allen key (regular right-handed thread on both pedals). A metal sleeve is placed on the inside. Its can be easily pulled out with a screwdriver or Allen key. This is because the purpose of this metal sleeve is to fix the pedal position on the axle. The end cap pushes the metal sleeve against the ball bearing.
After the sleeve is removed the axle nut is exposed. The axle nut can be unscrewed with a 6mm socket wrench. Keep in mind, that the axle nut on the right hand pedal is unscrewed clockwise (left-handed thread)! On the left hand pedal the axle nut has a conventional thread and is unscrewed counterclockwise (right-handed thread).
Having removed the axle nut the axle can now be remove from the pedal. The inside of the pedal still holds a ball bearing. You can push it out with an Allen key without much force.
The disassembled pedal looks like this:

Clean the axle thoroughly and reapply a generous amount of grease. Mind the seal on the axle! Its the seal the keeps the mud out. Clean it well and replace it if its damaged. A conventional o-ring or a combination of different sized o-rings should do the trick if you can’t sort an original seal.
In my case the ball bearing was fine on both pedals. Should yours be stuck replace it. Grease it as well before pushing it back into the pedal.
Reassembly is pretty straight forward. Push the axle into the pedal:

Screw on the axle nut. Push the metal sleeve in and screw in the end cap. Et voila.
Hope it helps!
