991010 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shim, 0.35 mm thick, listed for 19 applications across the D and IPS series and weighing 0.011 kg. It is the thicker of a graded pair — 991009 is the 0.15 mm step on the same 19 applications. Three other shim families in this run run the same 0.10 / 0.15 / 0.35 mm steps on different fitments, so check the application family as well as the thickness: 991097 to 991099 cover 30 applications, 991100 to 991102 cover 35, and 993258 to 993260 cover 18.

⚙️ Key Features

• 0.35 mm thick

🔌 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 — published weights are not a reliable guide across a graded shim set
• Build the stack up from measurement rather than replacing like for like; a worn shim rarely still measures its marked grade
