5. Set your hand against the frame down tube
with the end of your forefinger touching the
inside of the chainring (Figure 14).
6. Rotate the crank arm and note the amount
of wobble in the chainring.
7. Remove the crank arm by striking the arm
with the rubber mallet.
8. Rotate the spindle so the reference mark is
now at 3 o’clock, and repeat steps 3-7.
9. Rotate the spindle so the reference mark is
at 6 o’clock, and repeat steps 3-7.
10. Rotate the spindle so the reference mark is
at 9 o’clock, and repeat steps 3-7.
11. Note the position that produces the least
amount of chainring wobble. Install the crank
arm with the reference mark in that position.
PEDAL
The pedal on the right side has right-hand
threads. The pedal on the left side has left-
hand threads. Keep this in mind when remov-
ing and installing pedals onto the crank arms.
Removal
1. Rotate the crank so the arm with the pedal
being removed points towards the rear of the
E-Bike
®
.
2. Place a wrench onto the pedal flats so the
shaft of the wrench is horizontal and pointing
forward.
3. Break the pedal loose.
4. While facing the crank, hold the pedal with
one hand and the wrench with the other.
Rotate the pedal forward (normal pedaling
motion) and remove the pedal.
5. Repeat this procedure for the opposite
pedal.
Installation
1. Inspect the threads of the pedal stud. Install
the pedal with the right-hand thread onto the
right side of the E-Bike
®
. Install the pedal with
the left-hand threads onto the left side.
2. Grease the threads of the pedal stud.
3. Thread the left pedal onto the left crank arm.
Tighten the pedal stud as far as possible by
hand.
4. Face the pedal, and fit a wrench onto the
pedal flats. Hold the pedal with one hand and
hold the wrench with the other (Figure 15).
5. Rotate the crank arm rearward (opposite the
direction of normal pedal rotation) until the
pedal is snug.
6. Tighten the pedal to the torque specification
in Table 4.
CAUTION
Metal burrs are often created when the pedal
is tightened against the crank arm. Use a rag
to wipe up excess grease so you will not have
to deburr your finger.
7. Use a rag to wipe excess grease from the
crank arm.
8. Repeat this procedure for the right pedal.
BOTTOM-BRACKET CARTRIDGE
The E-Bike
®
uses a Chinhaur CH52-73 bot-
tom-bracket cartridge. This cartridge threads
into the right side of the bottom bracket. Its
adapter ring threads into the left side of the
bottom bracket.
The adapter ring on this cartridge has stan-
dard right-hand threads. The main body, how-
ever, has left-hand threads.
