Specifications

Problem:
The 6PK1140 ELAST V-ribbed belt (OE no. 03L903137G)
is being discontinued. The 6PK1070 replacement belt
(OE no. 03L903137) cannot, however, be installed directly.
Cause:
During plant trials the modiied design apparently contributed
to improved running properties, and because of that the new
design should now be used when the belt has to be replaced.
Solution:
The idler pulley (OE no. 03L145276) should be replaced with
a tensioning element with roller (OE no. 038903315AH).
Together with the new belt, the new tensioner is installed using
a new M8x50 hexagon head screw (OE no. N10640801).
