12.12.4 Diagnostic Information and Procedures
12.12.4.1 Diagnostic Information and Procedures

Vehicle Diagnostics

In the body repair process, professional technician will use panel calibrator, electronic measurement systems, sheet metal repair
machines, welding machines and a variety of cutting tools such as grinding. The repair will ensure that the vehicle will be restored
to the original conditions such as geometric dimensions and performance. However, some drive system faults or installation errors
that may lead to serious consequences may not be identified in the repair process. Therefore, in addition to make the necessary
body geometry inspection, you must pay particular attention to the following components:

–

Check to ensure that the steering mechanism and the steering rod can be correctly operated within the wheel turning range.
Visual inspect whether there are bent or cracked pieces.

–

Check all the running gear components (such as the fork tubes, vertical arm, sliding suspension arm, steering knuckle, stabilizer
bar, body frame and the overhang), whether there are bending, distortion and cracking.

–

Check whether the wheel and tire are damaged, rotating concentrically and unbalanced. Check tire tread and the sidewalls
incisions and tire pressure.

–

Check for damages in engine, gearbox and exhaust system mountings.

–

Road test to make sure the vehicle's driving performance, and then deliver the vehicle to the customer.

12.12.5 Removal and Installation
12.12.5.1 Removal and Installation

Note

Before  remove  any  key  components  from  the  vehicle
body,  you  must  use  a  universal-type  body  frame
correction  calibration  to  correct  body,  and  then
determine  the  damaged  components  that  need  to  be
replaced. Before welding, the parts must be accurately
positioned, and then you must measure to ensure that
components meet the body dimension requirements. In
the  welding  process,  you  must  measure  related
dimensions frequently to ensure proper assembly.
Before  removal,  you  must  understand  the  body  sheet
metal parts correlations. Please refer to the "Body Sheet
Metal Parts Map" below. It is not recommended to cut a
single part, as cutting and welding will affect the vehicle
stiffness, driving safety and maintenance convenience.

Removal Procedure:

1.

Remove  all  the  parts  relevant  to  the  component  that
needs to be replaced.

2.

Apply  sealant  and  anti-corrosion  material  when
necessary.

3.

Locate, mark and drill all the factory solder joints on the
component that needs to be replaced.

4.

Remove  the  damaged  component  that  needs  to  be
replaced.

5.

Remove material residue.

Installation Procedure:

1.

Treat the mating surface when necessary.

2.

According to the original welding type, you must choose
the correct welding techniques. Use shielded welding at
areas that are not convenient for welding. If you choose
to plug welding, please drill holes in the new components
for  plug  welding  seam.  Determine  the  diameter  and
spacing  according  to  the  original  plug  weld  hole  solder
joints.

3.

Temporarily put the new component on the vehicle.

4.

Install the new component with the correct mountings and
tighten (correct position the repair board).

5.

Frequently measure the location of the new component to
ensure that the assembly dimensions are correct.

6.

Weld.

7.

Clear all welded surfaces.

8.

Spray primer.

9.

If necessary, spray sealant and anti-corrosion material.

10. Install all the relevant sheet metals and components.
