Example: bearing puller (15112017000) During assembly, use new parts to replace parts that cannot be reused (e.g. self-locking screws and nuts, expansion screws, seals, sealing rings, O-rings, pins, and lock washers). In the case of certain screws, a screw adhesive (e.g. Loctite®) is required. Observe the manufacturer’s instructions.
