Fig. 222
Rollers/cam follower rollers are subject to high mechanical stress in the feed packer drum.
Because of this, they must be replaced when there is increased wear (bearing play).
To do this:
• Turn the packer manually until the roller or cam follower roller to be replaced can be
loosened through the opening (3) with an Allen wrench.
• Loosen the roller/cam follower roller
• Turn the packer further until the loosened roller/cam follower roller can be removed
through the opening (4)
• Remove the roller/cam follower roller through the opening (4) and install the new
roller/cam follower roller in reverse order
Tightening torques:
Large guide roller: Ø 72 (M 24 x 1.5) = 250 Nm
Small guide roller: Ø 40 (M 18 x 1.5) = 120 Nm
