Service Manual SIPLACE D1/D1i/D2/D2i 67
► Loosen the two M3 x 8 hexagon socket-head screws (6) and remove the "Y-brake outside" (5).
► Loosen the two M6 x 10 hexagon socket-head screws (7) and remove the deflection unit ’X’ (8).
► Remove the elastomeric spring (10) from the deflection unit.
Installing the deflection unit ’X’
Replacing the deflection unit (D4 shown as example)
► Fit the elastomeric spring (10) on the new deflection
unit (8).
► Fix the deflection unit (8) to the gantry, with the two
M6 x 10 hexagon socket-head screws (7).
► Align the "Y-brake outside" (5) so that it is parallel
with the braking surface and fix it to the deflection unit
(8) with the two M3 x 8 hexagon socket-head screws.
► Run the toothed belt (9) around the synchronizing
disk of the deflection unit (8).
