Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
Warning | Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant. | Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. | |
Warning | Risk of injury caused by body parts being pinched or crushed 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 it with the safety strut. | |

| Install | ||
1 | Tilt cab. | ||
2 | Remove soundproofing. | ||
3 | Drain off coolant. | ||
| |||
4.1 | Remove coolant drain fitting (18) from crankcase and replace with connection fitting (19). | ENGINE 471.9, 473.9 | |
Connection fitting to crankcase | |||
4.2 | Remove coolant drain fitting (18) from oil/coolant module and replace with connection fitting (19). | ENGINE 470.9 | |
Connection fitting on oil/coolant module | |||
5 | Install coolant filter (1) with bracket. | ||
Connection fitting to coolant filter | |||
6 | Attach bracket (10) with the larger bore to bracket of the steering gear. | Use M8x20 screw/bolt. | |
7 | Attach coolant line (8) with clamp and washer (9) to bracket (10). | Use M8x25 screw/bolt. | |
8 | Attach coolant line (8) with clamp to coolant filter (1). | Use M8x120 screw/bolt. | |
9 | Cut feed hose (5) to desired length and push chafe protection (6) into area of the vehicle frame. | ||
10 | Attach connectors to feed hose (5). | ||
11 | Heat chafe protection (6) with a heat gun uniformly all around and shrink on. | ||
12 | Attach feed hose (5) to connection fitting (19) of the engine and connection fitting of the coolant filter (1). | At the coolant filter (1), use the connection fitting on the inside at the vehicle frame. | |
13 | Attach chafe protection (3) in the area of the bracket for the coolant filter (1). | ||
14 | Install a chafe protection (7) in area of oil suction pipe and a chafe protection (7) in area of soundproofing bracket. | ||
15 | Connect feed hose (5) and hose of the steering gear oil reservoir with bracket (4). | ||
16 | Cut return hose (2) to desired length and attach connector. | ||
17 | Attach return hose (2) to coolant line (8) and attach to coolant filter (1). | ||
18 | Cut through coolant hose (17) and cut to desired length according to the length of the junction (16). | ||
19 | Install junction (16). | Select installation position of branch (16) according to existing as-built configuration. If applicable, install according to alternative routing (A, B, or C). | |
20 | Attach return hose (15) to junction (16). | ||
21 | Attach return hose (15) with clamp to bracket (14) of the charge air pipe. | Only if the return hose (15) is not routed with the alternative routing (A), (B), or (C). | |
22 | Cut return hose (15) to desired length and attach check valve (12). | Note flow direction. The coolant flows from the coolant filter (1) to the branch off (16). | |
23 | Cut return hose (11) to desired length and attach to check valve (12) and coolant line (8). | ||
24 | Attach a chafe protection (13) to the return hose (11) and a chafe protection (13) to the return hose (15). | ||
25 | Heat chafe protection (20) on return hose (15) with heat gun uniformly all around and shrink on. | Only if return hose (15) was installed with alternative routing (A) or (B). | |
26 | Route return hose (15) with chafe protection (21) on exhaust gas recirculation line. | Only if return hose (15) was installed with alternative routing (A) or (B). | |
27 | Check all retrofitted component parts for unobstructed movement and lack of chafing. | Due to the variety of the variants it can be necessary to adapt the displayed routing of the coolant hoses to the existing as-built configuration. Furthermore collisions with already mounted assembly parts should be avoided. If necessary alter the holder or routing of the electrical line. | |
28 | Install soundproofing. | ||
29 | Check whether soundproofing chafes on installed component parts. | If soundproofing chafes on an installed component part, | |
| |||
rework soundproofing. | |||
30 | Tilt back cab. | ||
31 | Fill in coolant. | ||
| |||
32 | Perform engine test run and check coolant filter (1) and all newly routed hoses for leak tightness. | Visual inspection. | |
Update Vehicle Documentation (VeDoc) | |||
33 | Add number of the variant parts list (SAA) 54225425 for the coolant filter (1). | Enter variant parts list (SAA) in design group DG 50. | |
34.1 | Add number of the variant parts list (SAA) 54225430 for the connection fitting (19) on the crankcase. | ENGINE 471.9, 473.9 | |
Enter variant parts list (SAA) in design group DG 50. | |||
