9809729 Hydraulic Cylinder | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hydraulic cylinder 9809729, listed at 1.662 kg, and confirmed by Volvo's own special tools catalogue under that exact designation. It publishes an application list for the first time: the D9, D11 and D13 ranges together with the TAD11-series industrial engines. It supersedes 9996161. This is workshop equipment rather than an engine component, and it is listed alongside pneumatic hydraulic pump 9809726 and puller 9986173, which carry the same published range.

⚙️ Key Features

🔌 Function

Converts hydraulic pressure into a controlled straight-line push, so a component can be pressed or drawn without shock loading.

⚠️ Common Signs of Failure

• Ram creeping back or refusing to hold under load
• Oil weeping past the rod seal or from the coupling
• Rod scored, pitted or bent
• The ram binding or moving unevenly through its stroke

🛠️ Service Notes

• Inspect the rod and the seal area before use; a scored rod destroys the seal and drops the load
• Stay within the rated pressure and keep clear of the line of force while the cylinder is loaded
• Retract and store the ram closed so the exposed rod is protected
