Fig. 8.10.4 shows the scheme of belts location. To mount the new belts, first unscrew nuts (7), (8), and (9) such that it
is possible to rotate the tensioners (4) and (5) around central axle. Clean the washers and surrounding area, and
check all bearings of pulley units/tensioners for too much clearance or rolling noise. Rotating the tensioner will allow
the centre distance to be reduced in such a way that the timing belt may be fitted without any applied force. Installation
with the use of force is NOT permissible at any time as this can damage the high quality, low-stretch tension cord and
other components. This damage is often not visible.
Arrange the belts in pos.10 as per the
scheme,
paying
attention
for
their
correct
orientation at every pulley. Loosen the nuts (7) to
the end of the bolt, and loosen the nuts on the half
moon (8), allowing the rotation of the tensioners
with minimal force.
Using nuts (7) tighten the belt, verifying again the
correct position of the two belts, and the correct
gearing in every pulley. Rotate the gear while
tensioning to allow for regular tension distribution
along the belt. Control the tension using Frequency
tension Tester (Optibelt 3 TT) (Fig. 8.10.3). Tension
in the
span А of the belt should be 115-120Hz.
It is possible to use the pre-installed
supports (11) as a reference to stop the tensioner
at the desired belt tension, provided that the
supports have not been moved from their factory
position.
8.11 REPLACING THE PULLEYS
Fully loosen the belt and remove (see the previous section).
After removing the belts, unscrew the four bolts of the pulleys on
top of the disc (Fig. 8.11.1) and replace.
8.12 REPLAING THE FRONT KEY JOINT OF THE PLANETARY PULLEY
Find the driving pulley unit of the planetary movement. Dismount the holder (Fig.8.10-11) and the adaptor underneath
(Fig.8.10-11), this will clear the accees to the front key joint.Fig. 8.11.1)
