⚙️ Key Features

• 0.034 kg
• Supersedes 21375755, catalogued before as a steering cylinder bellows
• 22 applications across the DPH, D, TSK and DPR ranges

🔌 Function

Covers the moving rod of the steering cylinder, keeping salt water and grit off it while allowing full travel.

⚠️ Common Signs of Failure

• Bellows split, perished or torn at a fold
• Water or grit found on the rod beneath it
• Clips loose so the ends have crept off
• Rod pitted or corroded where the cover has failed
• Steering feeling stiff or notchy from a scored rod

🛠️ Service Notes

• The number it replaces identifies it clearly as the steering cylinder bellows
• Renew it as soon as it splits - the rod and its seals are far more expensive than the cover
• Check the rod for pitting before fitting the new bellows, as a scored rod will destroy the seals
