What does this part do and what are the symptoms of wear?

The slew shaft housing is a key structural component that supports the pinion shaft in the "old type" slew mechanism. Its function is to keep the shaft in alignment and withstand enormous forces. If you hear loud "cracking" or metallic grinding during slewing, the slew is jerky or jams, and you find large metal shavings in the oil, this may indicate a cracked housing or worn bearing seats. This failure leads to the destruction of the pinion gear, rack, and the loss of the slew function.

Important Fitting / Service Tips

1.Diagnose the Cause of Failure

A cracked housing is usually a consequence, not the cause. It typically results from a worn-out pinion and slew rack. Always replace these components as a set.

2.Check Bearings and Bushes

Before installing the new housing, you must replace the bearings or bushes on which the pinion shaft operates.

3.Clean and Inspect Bores

Before installing new parts, thoroughly clean the entire kingpost frame of old grease and metal shavings.

4.Ensure Proper Lubrication

After installation, generously grease the teeth of the rack and pinion. Use high-quality grease, such as HYPTRON, and regularly check the lubrication status.

Frequently Asked Questions (FAQ)

Question: My slew is cracking and jamming. Will replacing the housing help?

Answer: No, replacing the housing alone will not solve the problem. Loud noises and jamming most often indicate broken teeth on the pinion gear or the rack. A cracked housing is usually a result of this failure.

Question: What's the difference between the "old type" slew and the new one?

Answer: The old type of slew (in machines before 1997) is based on a rack and pinion mechanism. The newer type uses hydraulic cylinders acting directly on the slew pins.

Question: Do I need special tools for installation?

Answer: Yes, overhauling the slew mechanism requires specialized tools (presses, pullers) and extensive knowledge. We recommend entrusting this repair to a qualified mechanic.
