Distinguishing between high-pressure pump and balance shaft bracing wheel
CAUTION
Hot components
•

Risk of burns



Let hot components cool down.



Wear personal protective gear.

Information
•

To prevent unnecessary repairs, it is important to distinguish between the high-pressure pump and
balance shaft bracing wheel when trying to pin-point the source of the noise.

•

A Nr.172 - stethoscope, for example, can be used to pin-point the noise sources.

•

If you cannot be sure that the high-pressure pump is causing the noise, the noise analysis
must be carried out using the stethoscope on the high-pressure pump of a comparable
vehicle.

Work Procedure: 1
2

Start the engine.
Nr.172 - Stethoscope must be used on the high-pressure pump  Contact point on high-pressure
pump -1- and then on the engine housing  Contact point on engine housing -2- in order to find the
rattling noise.
If you can clearly hear the rattling noise at the contact point on the high-pressure pump  Contact
point on high-pressure pump -1-, stop the engine and continue fault finding. Something else is
causing the fault.
