857624 Hydraulic Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hydraulic hose from the Marine Propulsion group, weighing 0.222 kg and listed for 112 applications across the AD, D, TMD, B, BB and DP ranges. It supersedes 854752, which was catalogued earlier both as a set and as a hose - so the older number may have supplied more than the single hose now issued against it, and it is worth checking what else the job needs.

⚙️ Key Features

🔌 Function

Carries hydraulic fluid under pressure between two points in the propulsion circuit while absorbing the movement between them.

⚠️ Common Signs of Failure

• Hydraulic fluid weeping at an end fitting or through the hose wall
• System slow, heavy or unresponsive under load
• Fluid level dropping with no obvious pool
• Outer cover crazed, chafed or cut back to the reinforcement
• Hose swelling or ballooning under pressure

🛠️ Service Notes

• The old number supplied a set - check whether the job needs more than this single hose
• Bleed the circuit fully after fitting and check operation through its full range before the boat is used
• Route and clip the hose exactly as the old one ran; chafe is the usual cause of failure
