Pedal cranks
Pedals
Verify regularly that the pedals (4) are firmly screwed
to the pedal cranks. Keep in mind that the pedals
have different threading.
The left side pedal is equipped with a left-handed
thread; it is tightened counterclockwise. The right
side pedal is equipped with a right-handed thread; it
is tightened clockwise.
The pedal axles are marked accordingly: (L) for the
left side, (R) for the right side.
Tighten the pedals (4) with a fork wrench SW 15.
The pedal cranks are tightened to a max. moment
of 35 Nm.
Tightening:
- Remove the protective caps (3) on both sides
and have the screws located underneath them
tightened.
NOTE
If the pedal cranks are already loosened then the
internal square drive is generally already deflected.
The pedal cranks and eventually the axle must then
be replaced. Disassemble well seated pedal cranks
only with a crank extractor, do never use force to knock
them out.
Before proceeding with the installation, the square
bearing surfaces of the crank and axle must be
completely oil and grease free.
WARNING
If you determine that the pedal cranks or the bot-
tom bracket are loose please consult your daum
electronic dealer.
The pedal cranks (1) can get loose with time and
extended driving. Check regularly if the pedal cranks
are firmly seated. There should be no perceivable
play (slack) when you strongly laterally pull the
pedal crank.
The bottom bracket (2) must also present no play
(slack) and the pedal crank must rotate easily, in that
case the bearing is in proper condition. Verify the
bottom bracket regularly. To perform this verification
move the pedal cranks laterally back and forth.
