6 - MAINTENANCE
Bucket teeth
The bucket teeth might be replaced because of either wearing or different operating needs.
NOTE: The wear of the bucket teeth depends upon several application factors. Examples of these factors are the
materials mainly handled on the jobsite and the operator's digging style.
NOTICE: some types of teeth have a symmetrical design that allows to flip them in case of uneven wear. Consult
the CASE CONSTRUCTION DEALER or the bucket supplier and make sure to understand the proper practices to
increase the service life of the teeth, as for example flipping and swapping.
NOTICE: Never work with a tooth that is completely worn: the adapter on the bucket will be seriously damaged.
The CASE CONSTRUCTION buckets are equipped with the SMARTFIT teeth system that allows either to easily
replace a worn tooth, or to easily switch between several types of teeth.
To replace a SMARTFIT bucket tooth proceed as fol-
lows:
1. Position the machine on a hard and level ground. Place
the bottom side of the bucket on a block so that the
bucket teeth are ahead of the block.

clockwise using an hexagonal wrench.

4. Extract the mounting pin.
5. Check the mounting pin for wear or damages.
6. Extract the tooth from the adapter on the bucket.
NOTICE: If the tooth does not easily come out from the
adapter, hit on its sides with a hammer as the mating sur-
faces come unstuck.
