Limitations for work on the chassis

Limitations for work on the chassis
General
General When planning bodybuilding work, it is important to know at an early stage what is permitted and not permitted for a vehicle.

This document describes some of the limitations that apply when fitting extra equip-ment and during bodywork.

More information can be found in the document for each application:

• Example of a search term: Box trucks.• Examples of filters:

– Type of work: Bodywork assembly.– Type of product: Tipper trucks.

More information on locating chassis components can be found on the vehicle’s chassis drawing, ICD (Individual Chassis Drawing).

IMPORTANT!

Follow legal requirements regarding what modifications are permitted on the vehi-cle.

More information on what modifications are permitted on a vehicle can be found in the document “Modifying Scania components and systems covered by a certificate”.

Blocking of moving components


Blocking of moving componentsWARNING!

Ensure that no loose objects can fall down from the load. Also ensure that, for exam-ple, load securing equipment is fastened. Falling objects may obstruct moving com-ponents such as the gearbox’s gear shift linkage, propeller shafts and power take-offs.

Hot componentsIMPORTANT!

Hot components require a safety clearance or heat shield to protect components which are not heat resistant.

More information is found in the document Risk of fire and damage in connection with hot components.


Accessibility requirements


Accessibility requirementsIMPORTANT!

The design of the bodywork must not prevent or impair the following:• Maintenance.• Repairs.• Lifting the engine, gearbox, shafts or other components in and out.• Tilting the cab.


Ventilating valve on the automatic gearbox

Location of ventilating valve.

Ventilating valve on the automatic gearboxWater must be prevented from entering the ventilating valve on the automatic gear-box.

Move the ventilating valve to another location if there is a risk of it being splashed with water, e.g. on fire engines, military vehicles and refuse collection trucks.

When moving the ventilating valve, the following applies:

• Use an adapter that converts the original connection from M10 to M12.• Use a hose with internal diameter of at least 9.5 mm.• Position the ventilating valve in a location which is well above the water level.

Note:The new venting system must not impair the air flow.


The radar’s field of view must not be obstructed

Location of radar.

The radar’s field of view must not be ob-structed

WARNING!The radar covers must be protected during re-painting or anti-corrosion treatment. The vehicle's radar, located at the front and on the sides, is very sensitive to interfer-ence and must not be covered or painted over. Its functionality depends on the thick-ness of the radar cover and its material properties. Obstructing the radar's field of view by, for example, covering with paint or stickers risks negatively affecting the vehicle's safety functions, resulting in unwanted braking or no braking.

WARNING!• The radar’s field of view must not be blocked by, for example, the frontal protec-

tion system or auxiliary lights.• Snow or other obstructions can reduce the radar’s field of view.• It is not permissible to move the radar.• If the radar is temporarily removed from its bracket, the plastic bushings must be

renewed before the radar is refitted.




Systems that are affected by the radar:

• Option Advanced emergency braking (AEB) (variant code 4335A). AEB in vehi-cles with front-mounted equipment may be switched off before the vehicle is driv-en away. The system can only be switched off momentarily, and must therefore be switched off every time the engine is started.

• Option Adaptive cruise control (variant code 3583A) depends on the radar to work. If the radar’s field of view is blocked, AICC should not be used.

More information on AEB can be found in the Driver’s Manual.

An extended area must be left radar free if there is a risk of the area shrinking during operation, for example due to dirt, snow or ice. The size of this area depends on the prevailing conditions in which the vehicle will be operated and also on how the structure is designed, e.g. whether there are compartments or openings where snow can accumulate.

The camera’s field of view must not be ob-structed

WARNING!• Obstructing the camera’s field of view risks negatively affecting the vehicle's

safety functions, resulting in unwanted braking or no braking. • It is not permissible to move the camera.

The camera has safety-critical functions. Auxiliary equipment on the front of the cab and stickers on the windscreen must not obstruct the camera. Blocking the camera can impair functionality and may cause the camera to shut down.

A camera is fitted in vehicles with any of the following options:

• Advanced emergency braking (AEB) (variant code 4335A).• Adaptive cruise control (variant code 3583A).• Scania lane departure warning (LDW1(variant code 3601A).

The camera scans the following area:

• Horizontal field of view: ±25° (calculated from the windscreen)• Vertical field of view: +14°/-21° (calculated from the horizontal plane).

The rain sensor's and light sensor’s field of view must not be obstructed

Location of rain sensor and light sensor.

The rain sensor's and light sensor’s field of view must not be obstructedThe Rain sensor (variant code 5121A) and Automatic dipped beam (variant code 5058A) options comprise a combined rain sensor and light sensor. Both options have safety-critical functions. The field of view of the sensors must not be obstructed by auxiliary equipment on the front of the cab or stickers on the windscreen. A blockage can impair functionality and may cause the sensors to shut down.

The sensors are located in front of the driver area on the lower edge of the wind-screen; see illustration. Leave 100 mm free space around the sensors.

WARNING!Obstructing the rain sensor's and light sensor’s field of view risks negatively affect-ing the vehicle’s safety functions.


Air intakes must not be obstructed

Location of the air intakes.

Air intakes must not be obstructed

WARNING! If the air intakes are obstructed, there is a risk of the engine overheating.

The air intakes have safety-critical functions. Auxiliary equipment on the front of the cab must not block the radiator or the engine's air intake on the front grille panel. This can cause an increase in temperature and may overheat the engine.


The brake control unit must not be moved

Location of the brake control unit.

The brake control unit must not be moved

WARNING!Moving the brake control unit, EBS (Electronic Brake System), can cause impaired braking or no braking action at all. It can also negatively affect the vehicle's safety-critical functions.

Minimum of 100 mm free space between side skirt and bodywork.

Space above the side skirtsNote:To be able to remove the side skirts, there must be at least 100 mm of free space be-tween the bodywork and the side skirt attachments.

The bodywork must not hinder removal of the side skirts. It must be possible to re-move the side skirts, e.g. during maintenance of the vehicle.


Space above the silencer


≥10

Minimum of 10 mm free space between the silencer heat shield and the bodywork.

Space above the silencerNote:To be able to remove the silencer, at least 10 mm of free space must be present be-tween the silencer heat shield and the bodywork.

The bodywork must not prevent the silencer from being removed; it must be possible to remove the silencer during, for example, vehicle maintenance.

When removing the silencer, it should be angled up before being pulled straight out.


Space above the reductant tank

Space above the reductant tankNote:Scania recommends testing with a filler nozzle to ensure there is adequate free space.

Extra space is required between the reductant tank and the bodywork when filling re-ductant. The reductant nozzle requires more space than the fuel nozzle.
