| Removing | ||
Danger! | Risk of injury caused by being caught or pinched as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure with the safety strut. | |
1 | Tilt cab | ||
| Notes on tilting the cab | ||
2 | Remove soundproofing on the right side of the engine | ||
3 | Detach coolant expansion reservoir from radiator and put to one side | Do not separate coolant lines. | |
4 | Remove charge air hose (8) | ||
5 | Remove noise encapsulation below the radiator. | ||
6 | Detach fan with viscous fan clutch (7) at intermediate piece | ||
Danger! | Risk of injury caused by pinching or crushing when working on springs or spring bodies that are under load | Use only approved tensioning devices; shield off hazard area if necessary. | |
7 | Swivel tensioning pulley of tensioning device (2) to the top and hold. | ||
8 | Remove alternator (6) poly-V-belt from belt pulley/vibration damper (3) and remove the belt pulley (1, 4) | On vehicles with code (H03) Air conditioning in front end, additionally on the belt pulley of the refrigerant compressor (5). | |
Danger! | Risk of injury caused by pinching or crushing when working on springs or spring bodies that are under load | Use only approved tensioning devices; shield off hazard area if necessary. | |
9 | Swivel back tensioning pulley of tensioning device (2) | ||
10 | Press fan with viscous fan clutch (7) to the front and take out poly-V-belt of generator (6) | Do not damage the poly-V-belt of the generator (6) when removing. | |
| Checking | ||
11 | Check belt pulleys and tensioning pulley for damage and smooth operation, replace if necessary | ||
12 | Inspect condition of poly-V-belt of generator (6), replace if necessary | ||
| Damage patterns of poly V-belt | ||
| Install | ||
13 | Push fan with viscous fan clutch (7) to the front and alternator (6) poly-V-belt on the belt pulley/vibration damper (3) and lay on belt pulleys (1, 4) | On vehicles with code (H03) Air conditioning in front end, additionally on the belt pulley of the refrigerant compressor (5). | |
Observe poly-V-belt routing plan. | |||
Danger! | Risk of injury caused by pinching or crushing when working on springs or spring bodies that are under load | Use only approved tensioning devices; shield off hazard area if necessary. | |
14 | Swivel tensioning pulley of tensioning device (2) to the top and hold. | ||
15 | Fit poly-V-belt of generator (6) onto the tensioning pulley of the tensioning device (2) and swivel back the tensioning device again | Ensure that the poly-V-belt of the generator (6) is seated correctly. | |
16 | Attach fan with viscous fan clutch (7) to the intermediate piece | | |
17 | Install noise encapsulation below the radiator. | ||
18 | Install charge air hose (8) | | |
19 | Attach coolant expansion tank on the radiator | ||
20 | Attach soundproofing to right side of the engine | ||
Danger! | Risk of injury caused by being caught or pinched as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure with the safety strut. | |
21 | Tilt cab back into driving position | ||
| Notes on tilting the cab |
