6.5.INSTALLING THE 160T i=2.1 BELT
TRANSMISSION
1. Remove the PTO guard and install to the cover plate
(1). Remove the mounting bolts of the small cover
plate and remove the cover plate (2) from the
mounting frame. These components will not be
needed later. See Figure 10.
2. Attach the upper belt pulley assembly (3) and the
regulator plate (4) to the chipper with the M12 bolts (5).
Tighten the bolts lightly so that the bearing housing
can be moved. See Figure 11.
3. Install the belt tightener (6) with the pin (7) and the
adjusting assembly with the pin with hole (8). Secure
the pins with cotter pins.
4. Install the belts on the upper belt pulley.
5. Push the lower belt pulley (9) onto the splined shaft
without the tightening cone (10) while placing the belts
into the grooves of the lower belt pulley.
6. Install the lower belt pulley tightening cone, NordLock
lock washer pairs, and tightening cone bolts (M12)
(11). Tighten lightly so that the lower belt pulley can be
moved on the splined shaft.
7. Check the alignment of the belts --- see Figure 12.
Adjust the alignment of the belt pulleys by moving the
upper belt pulley bearing housing and the lower belt
pulley.
8. Tighten the bolts of the upper belt pulley bearing
housing and the bolts of the lower belt pulley
tightening cone (5 and 11) M12 to 80 Nm.
9. Re---check the alignment of the belts and adjust if
necessary.
10.Adjust the belt tightener so that the roller touches the
belts lightly, then tighten the adjusting bolt (12) by two
to three turns. See Figure 13.
Be careful not to over--tighten, as this could
damage the belts!
11.Attach the plate (1) to the mounting frame with bolts
M8 (13).
12.Mount the chipper on the tractor. To check that
everything is in order, run the chipper for a while at
slow speed.
13.The belts must be run in, first without load for about ½
hour and then with the chipper loaded lightly for the
first 8 hours of actual use.
14.Observe the tightness of the belts and, if necessary,
adjust with the adjusting bolt (12).
