⚙️ Key Features

• Genuine Volvo Penta IPS-D internal oil-pump sleeve
• Works with spring-loaded ball and companion sleeve components
• Precision-machined internal transmission component
• Requires clean assembly and exact drive identification
• Engine type: Volvo Penta IPS marine propulsion drive

🔌 Function

Guides and supports the spring-loaded internal oil-control components in the IPS lubrication pump so pressure and flow are regulated correctly.

⚠️ Common Signs of Failure

• Scoring or wear inside the sleeve bore
• Low or unstable drive-oil pressure
• Sticking spring-loaded ball or valve action
• Metal debris found during drive overhaul
• Incorrect oil-pump operation after internal wear

🛠️ Service Notes

• Check which way round the sleeve goes before the old one comes out — sleeves are rarely symmetrical, and one end is usually chamfered or stepped to lead into the bore
• Clean and inspect the bore it seats in; a sleeve takes its final shape and fit from that bore, so corrosion, scoring or an oval bore will spoil a new part
• Draw or press the sleeve in square with the correct tool rather than driving it in — a sleeve started crooked will nip, and the material displaced by a hammer blow never fully recovers
• Renew any O-ring, seal or gasket that seats against the sleeve while it is out, and lubricate on assembly as the manual for your engine specifies
• Confirm the sleeve is fully home to the depth or flush condition the workshop manual gives before reassembling anything on top of it
