ST 1503 Manuel D'installation page 29

Pre-assemble the pulley (29) on the lever (31) pin (30),
making sure that the Seeger ring that retains the bearing
remains on the lever side, and fasten in place using the
screw (32), the washer (33) and the nut (34) using a tighten-
ing torque of 20-25 Nm.
Fit the lever with the tightener on the lifting module frame,
positioning the spacer (35) and the washer (36) in the se-
quence given.
Check that the belt remains centred on the tightener (29)
and, where necessary, insert the washer (36a) to achieve
perfect alignment.
Fit this ensemble using the screw (37), and the nut (38) with
a tightening torque of 20-25 Nm.
Grease the joint and check for correct movement of the
lever (31) and rotation of the tightener (29).
4. MOUNTING THE COMPLETE INTERFACE (Lifting +
PTO) ON THE MACHINE
▶ for NJ 92:
Remove the left side guard.
Unscrew the nuts (1) and (2), remove the steering rod (3)
and replace it with the rod (supplied separately) marked
with a red band.
NOTE - The replacement is required to prevent the
movement of the rod from interfering with parts of the
interface.
On completing the replacement, check the steering ge-
ometry as seen in the machine "Workshop Manual" .
Loosen the engine pulley fixing screw (4) and remove it to-
gether with the toothed locking washer (5).
Fit the supplementary pulley (6) using the same screw (4)
and washer (5), making sure the two drive planes coincide.
Use a power screwdriver, with a tightening torque of 45-50
Nm.
● Fit the complete interface on the machine, follow-
ing the procedure provided in Chap. 2.
Wind the transmission belt (7) around the pulley (6), making
sure that the left side remains inside the tightener (8).
Attach one end of the spring (11) to the tightener lever (12)
and the other to the adjuster (13).
Adjust the two nuts (14) until the spring (11) reaches a
length of 65 mm, measured on the spring assembly.
