Timing Belt Tensioner: Description and Operation

Mechanical Camshaft Belt Tensioner 

-

All B52XXX engines are equipped with a mechanical camshaft belt tensioner which replaces the old hydraulic tensioner (as of week 32 1997).

-

Rationalization: quality improvement.

-

The camshaft belt tensioners are adjusted using an eccentric to obtain the correct belt tension.

Check belt tension at every 30,000 mile / 45,000 km service.

The timing belt and camshaft belt tensioner replacement interval is 80,000 miles / 120,000 km as before. 

There are 2 new timing belts for the new belt tensioner depending on engine variant:
-

For 10 valves = Yellow text (138 teeth x 0.9 in.)

-

For 20 valves = Red text (142 teeth x 0.9 in.)
