Image 24: Nut to Adjust Spring Preload on Throttle Pedal

By turning the nut (16 mm AF spanner), the threaded stud is moved and the

spring preload changed. The basic setting is shown in the following image. The
pin in the slot shows the actual setting. The pin at the top means the minimum
spring preload is set. The pin at the bottom means the maximum spring preload

is set.
