(Retrofitting hydraulic damper on vehicles built before 1998)
Problem:
The belt drive makes noise after operating for a short time.
Cause:
The newly installed tension roller is not the correct distance from the engine and allows the belt to rub on the side of the inner flanged wheel
Solution:
When refitting vehicles built before and during 1998, the old version stud bolt (1) must be removed. The new version is then screwed into the same hole with a pre-mounted spacer (2). The problem here is that the manufacturer has two different thicknesses of the spacer (3.1) + (3.2) which define the distance from the roller to the engine. Despite the vehicle Identification No. or (prod. Month: 01/96) it is still not absolutely definitive which kit must be used. Assure proper belt alignment after tension roller is replaced. If misalignment occurs, there will be noises and catastrophic damage to the engine.
