SUBJECT:
CHECKING POLY-V-BELT DURING MAINTENANCE SERVICE ALL ENGINES WITH SINGLE BELT DRIVE
To detect any wear of the Poly-V-Belt at an early stage, it is very important that it be closely inspected every 15,000 miles during the maintenance
service*.
On diesel engines, also the belt tensioner should be visually inspected for proper seating and wear at this time.
Follow the illustrations and descriptions in Maintenance Manual Volume 2, Supplement 6, job number 1351 in order to assess the condition of the belt.

California version:
Recommended maintenance as defined by California Air Resources Board regulations. MERCEDES-BENZ urges that the maintenance be performed.
