It is possible to replace a defective steering gear cuff without dismantling the steering gear. To do this, it is enough to dismantle the head of the transverse steering rod. After loosening the fastening clamps, you can remove the defective cuff from the steering gear and replace it.
The head (2) of the transverse steering rod is easily removed from the steering arm (1) using a cam puller (3).
The photograph shows the transverse tie rod (3), the lock nut (2) of the transverse tie rod head (4) and the steering knuckle (1), into which the conical pivot pin of the transverse tie rod head is screwed.
Removal the servo pump
If the pump has to be removed due to installation work in the engine compartment, the pressure and return lines remain connected to prevent dirt from getting into the hydraulics. If the lines have to be removed from the pump, extreme caution is required. Even the smallest dirt particles in the hydraulic fluid can cause functional disturbances.
Remove the air pump housing, see chapter on the air filter.
Loosen the tension of the poly V-belt and remove it, see the chapter on the generator.
