991097 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shim, 0.10 mm thick, listed for 30 applications across the D and IPS series. It is the thinnest step of a three-part graded family: 991098 is 0.15 mm and 991099 is 0.35 mm, all three on the same 30 applications. Do not confuse this family with the 35-application family, which runs the identical steps under numbers 991100, 991101 and 991102.

⚙️ Key Features

• 0.10 mm thick
• 30 applications across the D and IPS series
• Graded family with 991098 at 0.15 mm and 991099 at 0.35 mm
• Distinct from the identically stepped 35-application family 991100 to 991102

🔌 Function

Packs out an assembly stack by a measured amount so the clearance or preload falls inside specification.

⚠️ Common Signs of Failure

• Whine, rumble or growl from the assembly the shim sits in
• Noticeable end float or free play at the shaft
• Clearance or preload measuring outside specification on reassembly
• Shim found fretted, bright-polished or dished when stripped out
• Measured thickness down on the stamped size

🛠️ Service Notes

• Order by the stamped or measured thickness — that is the only reliable way to separate a graded shim set
• Check the application count as well as the thickness: four shim families in this run use the same three thickness steps

📦 Condition

• Genuine Volvo Penta part
