7.11 MOUNTING AND TENSIONING A NEW PLANETARY BELT
Loosen the two bolts of the tensioning device (Fig.7.10.1). Make 2 marks on the
dismounted (untensioned) belt exactly 10 cm apart from one another (Fig.7.11.1).
The purpose is to measure 10.2 cm on the belt under tension - tension of 2%; a
maximum of 2.5% is allowed. ATTENTION: NEVER “OVER” TENSION THE BELT, THE
BELT WILL BE DAMAGED AND IT WILL NEVER RECOVER ITS ORIGINAL TENSION
Mount the new belt around the planetary pulleys and the aluminum casting
(Fig.7.11.2).
Mount the belt around the planetary pulley; check that the belt is behind the driving pulley (Fig.7.11.3). Put the belt around
the tensioning device (Fig.7.11.3). Put the belt around the driving pulley
(Fig.7.11.4). Begin to tension until the distance of 10 cm between the marks becomes 10.2 cm (Fig.7.11.5) (Fig.7.11.6). While
turning the bolt, rotate the planetary head so the belt can slide. (Fig.7.11.7). Do not forget to lock the tensioning device
(Fig.7.11.8).
