993813 Spacer Sleeve | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta spacer sleeve from the Fuel System group, weighing 0.016 kg and listed for 27 applications across the D, TAD and MD engine series. It supersedes part number 21272491, which earlier records carried under two different names - as a ring and as a spacer - so an older parts list may describe the same item either way.

⚙️ Key Features

• 0.016 kg
• Listed for 27 applications
• Fits D, TAD and MD series engines
• Supersedes 21272491, listed earlier as a ring and as a spacer
• Fuel System group

🔌 Function

Sets and holds the gap between two components, carrying the clamping load so the joint is not drawn up further than it should be.

⚠️ Common Signs of Failure

• Fastener losing torque or the joint working loose
• Sleeve found crushed, dished or worn on its end faces
• Bright fretting rings where it has been moving against the mating face
• Cracks or splits in the sleeve wall
• Fuel weeping at the joint the sleeve sets up

🛠️ Service Notes

• If your paperwork calls for 21272491 - whether it names it a ring or a spacer - this is the number that now covers it
• Renew a crushed sleeve rather than reusing it, as a shortened sleeve will not restore the clamp
