PRONAR GP200 SECTION 5
5.10
If one of the belts is damaged, replace it. There are three serpentine belts (part number: 10
PL 1397) in the drive transmission system. To replace the serpentine belt, dismount the
covers (3) and (4) (FIGURE 5.5) and the tensioner bracket (2). To replace the drive belts
installed on the motor pulley, dismount also the motor shield (8), the hydraulic motor (7)
together with the motor spacer (10) and the cover plates (5). After dismounting the tensioner
bracket (2) and the motor, loosen the bolts (7) (FIGURE 5.4) that fix the pulley bracket and
then, move the pulley so far as to make it possible to remove the serpentine belt from the
pulley.
After mounting the new belts and tensioner brackets, the cover plate (5) can be mounted.
The cover plate (5) must be centred in relation to the motor pulley axle. To do this, use the
centring sleeve (9) included in the set of special wrenches. Install the centring sleeve (9) in
the opening of the cover plate (5) and the pulley, tighten the fixing bolts (6) and remove the
centring sleeve from the cover plate opening. Now, the hydraulic motor (7) and the shield (8)
can be installed.
After the replacement, adjust the serpentine belts according to Section 5.3.1.
