2.4 Flexible Tip Wiper (If applicable)
The intake chamber has a flexible tip wiper
bolted to the left hand side (viewed from the
driven end). The tip wiper levels material as it
moves out of the intake area into the casing.
This leveling action ensures even flow,
reduces wear rates and avoids' out-of-round'
wear within the casing.
- Check the flexible tip wiper during every
scheduled tip servicing –

housed in a sealed housing. The housing must
remain sealed and slightly lubricated to prevent
corrosion that will prevent these bearings from
floating. Remove the cover plate only if
operational problems are suspected.
Ensure that the housing is slightly lubricated before
replacing the cover.
Tapered bearing type: Each rotor shaft bearing is
housed in a sealed grease box and does not require
routine lubrication. Remove the cover plate only if
operational problems are suspected. Ensure that
the grease box is fully packed with grease before
replacing the cover.
