9998580 Sleeve | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta special tool 9998580, listed at 0.073 kg and catalogued here simply as a sleeve. Volvo's own special tools catalogue is more specific: it designates the item a protective sleeve, so its job is to shield a component during fitting rather than to drive one home. It publishes an application list too, the D9, D11 and D13 ranges together with the TAD11-series industrial engines. A second plain sleeve, 9998598, is listed at 0.372 kg.

⚙️ Key Features

• 0.073 kg

• Published for the D9, D11 and D13 ranges and the TAD11-series industrial engines

🔌 Function

Covers the splines, thread or step a seal or component has to pass over during assembly, so the sealing lip is not cut or turned back on the way on.

⚠️ Common Signs of Failure

• Outer surface scored, burred or picked up, so it marks what it is meant to protect
• Ends bruised or belled over
• Split or cracked along the wall
• Sleeve no longer a snug fit, letting the component enter off square

🛠️ Service Notes

• Check the outer surface is smooth before use; once it is burred, the sleeve damages the seal it was fitted to protect
• Leave it in place until the seal is fully over the step, then withdraw it rather than pulling the seal back
