4. If necessary, install bolt (11) and tension the new
belt. Refer to “Inspection” for more information.
5. When required tension is correct, tighten bolt (11)
to a torque of 47 N·m (34 lb ft). Tighten bolt (6) to
a torque of 70 N·m (51 lb ft). Then, install the
cover guards, refer to “Inspection” for more

5. The belt tension must be checked at position A.
Use a suitable spring balance and a suitable
straight edge to check the belt tension.
6. The belt tension should be 591 N (132.9 lb) with a
maximum deflection at position B of 16 mm
(0.63 inch).
7. Adjust the belts if the belt tension exceeds or is
below 591 N (132.9 lb). Refer to “Adjustment” for
more information.
