979138 Spacer Sleeve | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta spacer sleeve weighing 0.051 kg and listed for 6 applications across the D and TAD series. It is one of three spacer sleeves in this run, alongside 979117 and 980935; none of them publish a bore or length, so the engine fitment and part number are the only reliable way to separate them.

🚤 Compatibility

• Volvo Penta D8A5-A MH
• Volvo Penta D8A6-A MH
• Volvo Penta D8A1-A MP
• Volvo Penta TAD1381-85VE

⚙️ Key Features

• 0.051 kg
• Listed for 6 applications across the D and TAD series
• Narrower fitment than sleeve 979117, which covers 28 applications
• Bore and length are not published - order by part number

🔌 Function

Maintains a set distance between two parts so the bolt through it can be tightened to full torque without collapsing the joint.

⚠️ Common Signs of Failure

• Joint slackening off and the fastener needing repeated retightening
• Bore scored or ovalled where the bolt has moved in it
• Sleeve ends flared or peened
• Seizure between sleeve and fastener from corrosion

🛠️ Service Notes

• Compare against the old part rather than against the other sleeves in this run - the listings give nothing to measure
• Renew the fastener as well if it has picked up on the sleeve bore

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
