Removing Throttle Potentiometer
1. Undo air conditioning compressor and set it aside with the hoses connected so that coolant cannot escape.
CAUTION: Do not tower engine too far.
To avoid damage to the noses, tines and engine, the engine must only be towered by approx. 30 mm - 40 mm.
NOTE: Observe installation position of the components.
2. Lower engine. Secure the engine against falling down with a workshop jack. Undo both hexagon nuts on the engine mounts on the right and left.
The engine can now be lowered by 30 mm - 40 mm.
