Read before you buy

As a consumer, you are asked to check the goods immediately upon delivery for completeness, obvious defects and damage and to inform us and the shipper about any complaints as quickly as possible. Failure to do so will not affect your statutory warranty claims in any way.

It is in your own interest, in particular, to be sure to adhere to the procedures outlined below for

– overt transport damage
– concealed transport damage.

1. Overt transport damage

In the event of overt transport damage, please unpack the consignment in the presence of the lorry driver making the delivery and have the damage noted and certified on the proof of delivery or delivery note with the date and time. Photographs of the damaged consignment and damaged goods have proven to be useful for preserving evidence. Please also note the licence plate number of the lorry. Then please inform us immediately

2. Concealed transport damage

Concealed transport damage exists if it is only recognised after acceptance of the consignment.
Check the goods immediately after receipt. You must report the damage to us immediately. Defects due to improper handling during transport that are discovered later will no longer be recognised by insurance providers, and they will not provide compensation. When making your report, describe the damage that has occurred as accurately as possible and be sure to always keep the goods, including the outer packaging and shipping packaging, for checking the transport damage. Photographs of the damaged consignment and damaged goods have proven to be useful for preserving evidence. We will then contact you promptly and arrange for further steps to be taken.

3. Other information

Please note that carriers often try to refuse to accept the damage. Therefore, please pay attention to what you sign on the damage form.

If the shipment was visibly damaged from the outside and you have accepted the shipment without any complaints, then all liability is excluded, and you will have to bear the damage alone.

If the shipment was not visibly damaged from the outside, carriers will often try to refuse to process the damage. They then justify this by saying that no transport damage can have occurred precisely because of the damage that is not identifiable from the outside. This indirectly implies that you, as a rule, have damaged the goods or that we have intentionally shipped damaged goods. In these cases, look for signs of external forceful impact on the package, such as slight dents, and have them recorded in the damage report. Photographs of the damaged consignment and damaged goods have proven to be useful for preserving evidence.

ENGINE INSTALLATION

Be sure to observe the following installation instructions for the motor

 

Severe damage often occurs following an engine repair. Faults that are not resolved in the periphery of the engine, whether mechanical or electrical, can lead to costly consequential faults. With the following checklist, the majority of possible sources of trouble can be eliminated during engine installation.

Engine mechanics

Components

Activity

Background

Intake system

Check, clean

There may still be fragments, metal chips or other soiling in the intake system from engine damage.
If these are not removed, they can cause more engine damage or premature wear.

Charge air cooler

Clean or
replace

Following engine damage, there are often large quantities of engine oil in the charge air cooler.
If a new engine is connected, this can lead directly to engine damage.

Turbocharger
connecting lines

Check, clean,
replace

Supply and return lines are blocked with carbon due to thermal influences, the resulting inadequate oil
supply leads to turbocharger damage. Mechanically clean the lines (with a metal brush), or replace them.
Blowing out lines with compressed air is not recommended.

Turbocharger

Check, replace

The turbine and compressor impellers must be in impeccable condition, they must not be deformed or
cracked, or have ground against the housing.

Oil filter, oil cooler and
oil lines

Clean or
replace

Metal chips resulting from engine damage can be flushed to the clean side of the oil filter. Thoroughly
wash out and clean the oil cooler and filter housing. Blowing out lines with compressed air is not
recommended. The oil cooler and connecting lines should be replaced completely.

Oil system

Fill

After you have connected it to all components supplied with pressure oil (oil cooler, turbocharger,
hydraulic pumps, etc.), fill the engine with pressure oil to prevent dry running and damage to bearings.
This process is described in detail in Service Information SI 1639.

Exhaust system

Check, clean,
replace

As a result of engine damage, fragments of pistons, valves and the turbocharger, as well as fuel and oil,
enter the exhaust system and cause further damage on the catalytic converter or particulate filter.

Fuel filter and filter
housing

Check, clean

Injectors and high-pressure pumps in diesel engines are extremely sensitive to fuel contamination.
It is therefore advisable to also check these following engine reconditioning and to clean or replace them
if necessary.

Fuel/
contents of the fuel
tank

Check, replace
if necessary

Filling the tank with the incorrect fuel frequently leads to engine damage. If there is any uncertainty
regarding the composition of the existing contents of the tank, empty the tank completely and fill with the
specified fuel.

Cooling system

Clean

Before installing the engine, rinse cooling system components remaining in the vehicle with clean water.

Coolant agent

Replace

Only use specified coolant agent in the correct dilution. Do not start up the engine, even briefly, without
filling the cooling system. If the water pump runs dry, the sliding ring seal burns immediately and the
pump starts to leak.

 

Before starting the new engine

Components

Activity

Background

Electric
Cables and hose
connections

Check

Check correct connections using a circuit diagram of all vacuum lines and electrical plug-in connections.
This also applies to earth cables between the engine and the body/starter battery. This prevents damage
to electrical components and cables due to overstressing.

Engine

Start

Before starting up the engine, oil pressure must be built up. If necessary, take suitable action to ensure
that the engine does not start up before oil pressure has built up.

Engine

After start-up

After start-up, do not damage the engine through repeated early acceleration. The oil system needs some
time until it has vented completely and all components are supplied with fresh oil.

 

Electronic components

Components

Activity

Background

Engine control unit(s)

Fault check

Read out the fault code memory, note the diagnostic trouble codes and then delete the fault code
memory.

Engine electronics with
components

Actuator test

The actuator test is used to check the function of the relevant components.
This is helpful for flagging up interchanged plugs and faulty actuators, for example.

Carry out
adaptation

Adapt, teach in

Today, many components have to be adapted following replacement. These include, for example:
Air mass sensors, stepper motors, throttle valves, regulating throttles and EGR valves.
Also see Pierbug Service Information SI 0090 and SI 0092.

Common rail injectors

Programming

After being swapped or replaced, common rail injectors must be programmed in the control unit
separately for each cylinder. This is essential in order to compensate for manufacturing tolerances. To
this aim, a code is printed on every injector, which must be saved/entered in the control unit using a
diagnostic tester.
The injectors from some manufacturers do not have a code, and programming is not necessary. These
injectors program themselves via an installed invariable resistor. They can be identified via a 4-pin plug
and the lack of an imprint.

 

Test run/finishing work/final inspection

Components

Activity

Background

Test run

Note OBD
driving cycle

The test run should incorporate a cold start, warm-up, urban traffic, driving on a highway and a
motorway.
In addition, please bear in mind that in passenger cars, for example, some components are no longer
monitored by the OBD at velocities in excess of 120 km/h.

Fault code memory

Check, delete

Always check and delete the fault code memory before and after the test run, even if the MIL (malfunction
indicator lamp) does not light up during or after the test run. With OBD systems, the malfunction indicator
lamp is often only activated after a fault has occurred twice. However, a diagnostic trouble code is stored
in the fault code memory the first time this fault occurs.
