Disc gangs assembly sequence
IMPORTANT Check the correct side of the bearings and spacer spools according
to the concavity of the disc blades.
Place the outer lock (A) along with the axle (B).
Tighten the nut (C) passing 5 mm from the axle face.
Place the disc blades (D), bearings (E) and spacer spools (F), following the instructions
on the previous pages (14 to 16).
Place the inner lock (G) and nut (C-1).
Place the bolt (H) that holds the lock nut (I), along with the spring washer and nut
(only on the outer side of the gangs).
Use the wrenches (A) from page 13 to tight the gangs, as follows:
1) Place one of the wrenches on the outer side of the gang (locked side), supporting
it on the ground.
2) On the inner side, use the other wrench and tighten the gangs to get maximum
torque.
3) To tighten, the gangs must remain underpinned with a piece of wood or another
object, preventing it from moving.
Lastly, put the bolt (H-1) and place the lock nut (I-1), fixing with a spring washer and
nut.
