# 3809982 Cylinder | Genuine Volvo Penta Part

## 🔧 Product Description

The strength required to steer a boat with a hydraulic steering system is inversely proportional to the number of turns of the wheel lock-to-lock. Wheel turns are determined by the ratio between the cylinder volume, the pump displacement and the free movement of the steering device. A large cylinder volume with a small pump displacement gives more wheel turns; a small cylinder volume with a large pump displacement gives fewer. Fewer wheel turns means quicker steering response but more effort; more wheel turns means slower response but less effort. Three steering cylinders are available, all for rudder installations, with volumes of 116 cm3, 168 cm3 and 215 cm3. This is the 168 cm3 cylinder: 682 kg output force, 178 mm stroke and 87 kgm torque, with three-eighths inch (9.5 mm) fittings for high pressure flexible hose.

## ⚠️ Common Signs of Failure

-   Hydraulic fluid weeping at the rod or end glands
-   Rod scored, pitted or bent
-   Air in the circuit giving a soft helm
-   Travel uneven between port and starboard

## 🛠️ Service Notes

-   The middle of three: it shares the 178 mm stroke with the 116 cm3 cylinder 3809981 but the same 682 kg output force as the 215 cm3 cylinder 3809983, so volume and stroke together are what separate them
-   Match the cylinder volume to the helm pump displacement before ordering, since the pair set the number of wheel turns lock to lock
-   Bleed thoroughly after fitting and check for leaks with the steering held hard over
-   Three cylinders are listed and volume, stroke and output force are what separate them: 3809981 is 116 cm3, 178 mm stroke, 455 kg output force; 3809983 is 215 cm3, 228 mm stroke, 682 kg output force
-   Cylinder volume and helm pump displacement together set how many turns the wheel takes lock to lock
-   High pressure flexible nylon hose 3/8 inch is 1140584, air bleed hose is 192618 and the hydraulic oil is 22618337
