23.4 Replacing Rolls
Fig.
Rolls are subject to high mechanical stress in the packer drum. Therefore it is necessary to
replace them in case of increased wear (bearing play).
To do this:
• Turn packer manually until the roll to be replaced can be released through the opening (3)
by means of hexagon wrench.
• Loosen roll.
• Turn packer until the released roll can be removed from the opening (4).
• Remove roll from opening (4) and mount new roll in reverse order.
Tightening torques:
Big guide roller: Ø 72 (M24 x 1,5) = 220 Nm
Small guide roller: Ø 47 (M20 x 1,5) = 120 Nm
