The sideshift clamp nut is a key component that secures the mounting bolt of the rear arm carriage. In construction machinery, where vibrations are a daily occurrence, a standard nut is not enough. Symptoms of wear include the inability to torque the bolt correctly, damaged threads, or cracks. Using an incorrect or worn nut leads to the connection loosening, which results in arm "drifting" and risks a serious failure.

Using a dedicated high-strength nut prevents the loosening of a key connection in the excavator arm.
A secure fastening protects the sideshift frame and rams from damage that could result from operating with a loose bolt.
For 100% certainty, nuts in critical, high-load connections should be replaced with new ones every time the bolt is removed.
For 100% safety and reliability, this nut should always be replaced with a new one whenever the bolt (123/00928) is removed and reinstalled.
Answer: Absolutely not. Standard nuts do not have the required strength class and can crack under load, leading to a serious failure.
Question: Is this a self-locking (Nyloc) nut?Answer: No, it is a high-tensile steel nut. Its securing power comes from being torqued correctly and the quality of its material, not a nylon insert.
