CHECKING THE TENSIONER SPRING TENSION:
Belt drive systems equipped with automatic (spring)
belt tensioners cannot be adjusted or repaired. The
automatic belt tensioner is designed to maintain proper
belt tension over the life of the belt. If tensioner spring
tension is not within specification, replace tensioner
assembly.
The belt tensioner is designed to operate within the limit
of arm movement provided by the cast stops (
A
and
B
)
when correct belt length and geometry is used.
Visually inspect cast stops (
A
and
B
) on belt tensioner
assembly. If the tensioner stop on swing arm (
A
) is
hitting the fixed stop (
B
), check mounting brackets
(alternator, belt tensioner, idler pulley, etc.) and the belt
length. Replace belt as needed.
CHECKING THE BELT TENSION WITH A SMARTPHONE:
Nowadays, it is possible to check a belt tension in using
an application on a smartphone. Several applications
may be tested and used. In the majority of cases, results
are very performing.
The principle consists of the comparison of the belt
vibration against an algorythm stored in the application.
Among the applications freely available, one may
consider one of these :
•
Tension 2Go APP (Continental)
•
PT Toolkit APP (Gates)
• Easy tension APP (Hutchinson)
MISCELLANEOUS
CAMSHAFT TIMING
From the two camshafts down to the crankshaft,
N6.CR2 engine timing is ordered through a gear system.
The complete assembly is service free. Inspection is
occuring only during a major service on the engine.
