Accelerator pedal Removal / Installation; C30, S40, V50, and C70
In order to remove / replace the climate system (pollen) filter on C30, S40, V50, and C70 vehicles, the accelerator pedal needs to be removed / reinstalled. While removing the pedal, the bolts (studs) used to hold the accelerator pedal assembly in place may become loose when the "compressed nuts" are removed by the technician. The installation process of the bolts (studs) was modified to reduce the possibility of this from the following chassis numbers; S40-92141 / V50-91193. The nuts holding the accelerator pedal changed from compressed nuts to "regular" M6 nuts from the following chassis numbers; 544-276806 / 545-291234 / 542-14430.
IMPORTANT NOTE:
Many of the bolts (studs) loosened from their mounts have been caused by the use of pneumatic tools (i.e. air ratchets). Regardless of the chassis number or production modifications, pneumatic tools should never be used to remove / install the accelerator pedal mounting nuts!
During accelerator pedal reinstallation, any previously installed compressed nuts should be replaced with regular M6 nuts, P/N 985919 (x3).
