| Remove/Install | ||
1 | Unscrew floor plate in center aisle of passenger compartment and remove | ||
2 | Position vehicle with front wheels on turntables | The steering axle (front axle) must bear the vehicle weight, i.e. the vehicle must not be raised at the front axle. | |
| Inspecting, setting | ||
3 | Check center position of steering linkage and adjust if necessary | ||
4 | Check wheel stop and adjust if necessary | ||
5 | Connect oil pressure gauge | ||
Danger! | Risk of accident. Accidents may result if the vehicle starts off unintentionally with the engine running. Risk of injury as working around the engine during start-up or while running may result in contusions and burns | Secure vehicle to prevent it from moving. | |
6 | Start engine and run at idle speed | ||
7 | Turn steering wheel to stop | It must be possible to turn the steering wheel without much force. | |
8 | Turn steering wheel again briefly (maximum 5 second intervals) until a firm steering wheel stop is achieved | - Turning the steering wheel up to a firm stop overcomes the return force of the steering valve. - The necessary operating force at the steering wheel is approx. 100 to 200 N. | |
9 | Read oil pressure value on pressure gage | If the value is not within the permissible range, the steering limiter must be readjusted. | |
Set pressure of hydraulic steering limit for 100 to 200 N operating force at steering wheel to steering stop | |||
10 | Renew bolts (1, 2) and sliding bushes | This step is only necessary if - the oil pressure does not fall to the specified value (larger value of oil pressure than specified value), - the oil pressure falls to the specified value but there is no gap or too large a gap at the wheel stops. If not renewed, the sliding bushes would have to be pushed onto the press seating and that is not permissible. Before carrying out this step - stop the engine, - put the front wheels in the straight-ahead position. | |

Adjusting | |||
11 | Adjusting steering limiter | - To do this, the front wheels must be forced to the maximum right and left wheel locks. The steering wheel must be turned only with increased force with or without hydraulic assistance. - The sliding sleeves on the two bolts (1,2) are then pushed automatically into their respective switch-off positions on these bolts. - Check the steering limiter again. |
