The slew column cover is a key bodywork component of an excavator. Its job is to protect expensive and sensitive components – the slew motor, planetary gearbox, and the rotary joint – from water, dust, impacts, and debris. If your cover is cracked, has holes, is missing pieces, or is completely missing, it is a sign that it needs immediate replacement. A faulty cover leads to rapid wear of the slew ring, corrosion and failure of hydraulics, and poses a hazard to personnel working around the machine.
Before fitting the new cover, thoroughly inspect the condition of the threads and brackets on the machine's frame. Damaged mountings will prevent a secure installation.
Any additional brackets, holders, or other elements must be transferred from the old, damaged cover if they are not part of the new kit.
We recommend using new mounting bolts with rubber washers to ensure a secure fit and to dampen vibrations.
Access to the slew motor and rotary joint is a perfect opportunity to clean them of dirt and inspect for any leaks.
Answer: Yes. Even a small crack allows water and dirt to enter, which act like a grinding paste on the slew ring and rotary joint seals, leading to very expensive failures.
Question: Why is replacing this cover so important?Answer: The cover protects components worth thousands (slew motor, rotary joint, slew ring). The cost of a new cover is negligible compared to the potential repair costs of these components.
