Maintenance
Changing and adjusting the unaligned double discs
The maintenance of the unaligned double discs must be done when a clearance between
the discs are noted.
Remove the bolts (A) and spring washers from the hub (B).
After changing the discs (C), retighten both sides of the hub.
After assembling the hubs, be sure that they can swing freely. If there is any contact
between them or if they are being forced, add a thrust washer (D) on the side with more
wear. To do so, remove from one side of the disc and place on the other side.
After this procedure, the disc blades (C) will work free and there will not have any
friction between them.
