9.2.3 Cautions
• The pedelec should be stored in a ventilated dry room. Avoid storing the
pedelec near strong mag-
netic objects.
• Should not be used for a long time overload.
• Should avoid wading to use.
Do not contact magnetic materials with products (mainly axes)
It is forbidden to be knocked during product transportation and installation.
At installation and disassembly it shall be carried out in accordance with the
prescribed proceduresto prevent break line.
9.3 SENSOR INSTALLATION
9.3.1 List of Tools to be used
| Use of the Tools | Tools |
|---|---|
| Locking ring (left cap) Bracket locking ring | Spanner (TL-UN65) |
| Left and right cap | Spanner |
| Check BB | Internal hex wrench |
| Check | GO – NO GO GAUGES |
9.3.2 Installation Drawing
- Left cap
- Locking ring (left cap)
- Shaft Sensor (including right cap)
- Chain wheel
- Bracket locking ring
- Rubber grommet 7. BB
- Right crank
- Left crank 10. M
- socket hexagon screw
9.3.3 Check BB
heck whether there are any iron chips, paint or burrs on the inner thread of
the BB. If any, please clean it up.
② The spec. of the inner thread of the BB is BC1.37’’×24, please must use the
tool (GO – NO GO GAUGES) to test. ③ Must check the parallelism and
concentricity of the BB, the
requirement refer to the figure below:
Check the length of the BB, it shall meet the
requirement of the tolerance (±0.2mm).
Section1: 0.15mm
Section2: 0.10mm
Section3: 0.05mm
Section4: 0.01mm
The concentricity of BB must meet requirement of section 3 (0.05mm)
9.3.4 Install the Sensor
-
Use spanner to fasten the left cap (non-sprocket side) into the BB. Max.
torque is 30N.m.
NOTE: If the form and position tolerance of the BB is at 0.1mm – 0.15mm, it is recommended that the wrench torque is controlled at 30 – 40 N.m during the installation of the locking cap.
Use spanner to fasten the right cap
(sprocket side) into the BB, max.torque is 30N.m.
NOTE: If the form and position tolerance of the BB is at 0.1mm – 0.15mm,
it is recommended that the wrench torque is controlled at 30 – 40 N.m during
the installation of the locking cap.
-
Use spanner (TL-UN65) to fasten the left locking ring into the left cap, max. torque is 8N.m, please make sure that the shaft can rotate smoothly, test method: place the crank (with pedal) horizontally, the crank can freely droop.
NOTE: If the form and position tolerance of the BB is at 0.1mm – 0.15mm, it is recommended that the wrench torque iscontrolled at 10 – 20 N.m during the installation of the locking cap. Please make sure that the shaft canrotate smoothly. -
Use spanner (TL-UN65) to fasten the left locking ring into the left cap, max.
torque is 8N.m, please make sure that the shaft can rotate smoothly, test
method: place the crank (with pedal) horizontally, the crank can freely droop.
NOTE: If the form and position tolerance of the BB is at 0.1mm – 0.15mm,
it is recommended that the wrench torque is controlled at 10 – 20 N.m during
the installation of the locking cap. Please make sure that the shaft can
rotate smoothly.
6. Push the chain wheel onto the sensor along the spline. 7. Use spanner to
fasten the support locking ring into the external thread of the sensor, max.
torque is 35N.m.
NOTE: It is recommended that the wrench torque is controlled at 25 – 35
N.m during the installation of the locking ring.
8. On both ends of shaft, use
Internal hex wrench to fasten M8x15 screws onto left and right crank sets,
max. torque.is 35N.m. NOTE: It is recommended that the wrench torque is
controlled at 25 – 35 N.m during the installation of the screws.
