8.4 DISMOUNTING/MOUNTING THE ENGINE AND CHANGE BELT
Separate the head from the carriage
(see previous chapter). Remove the
front and back belt protectors (Fig.
8.4.1-7) (Fig. 8.4.1-6). Loosen the
motor base plate (Fig. 8.4.2_5) and
release the tensioner assembly (Fig.
8.4.3_4). Take off the engine with the
motor base plate.
Reassemble in the same manner. (Fig.
8.4.5), Tension the belt with bolt (4) on
(fig. 8.4.4). The belt tension can be
tested with a Frequency tension Tester
Optibelt 3 TT. The readings should be
195...205 Hz.
If you do not have a
Frequency tension Tester, use the
already set limit of the movement of
the motor base plate
ATTENTION:
NEVER “OVER” TENSION THE

Reassemble in the same manner. Do not forget to mount the washer back on the shaft
(Fig. 8.5.4). The torque on the front nut (Fig. 8.5.3) to mount the pulley and
clutch should be 70 Nm or 52 lbf.ft (Fig. 8.5.2 and Fig. 8.5.3).
