Structure and Function
5.3.4 Change and prestressing of synchronous belt
1. Uncouple screw and move injection cylinder to rear end
position.
2. Loosen fastening screws (Item 1; 3x) and hand-tighten so
that no gap can form between the guiding platen (Item 2) and
hydraulic motor.
3. Move hydraulic motor to upper end position by means of
cam (Item 3).
4. Remove synchronous belt wheel (Item 4) from shaft.
5. Put synchronous belt over wheel and position on shaft; in
doing so, take care to push the synchronous belt also over the
upper synchronous belt wheel.
6. Use cam (Item 3) to prestress synchronous belt (in keeping
with instruction item 2. above), with a pressure of 140 N acting
on the centre of the synchronous belt; depth of impression: 2
mm (0.08 inch).
7. Secure hydraulic motor with fastening screws (Item 1; 3x)
(maximum torque: 80 Nm; 110 ft lb).
