978917 Shim | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta shim 0.50 mm thick, listed for 54 applications across D, TMD, AD, IPS, HS and TAMD engines. A second 0.50 mm shim, 978915, is listed here against a narrower application set that does not include IPS, so check the engine family carefully — the thickness alone will not tell you which of the two you need.

🚤 Compatibility

• Engine Family: D, TMD, AD, IPS, HS, TAMD, KAD, KAMD
• HP Range: 260-480 HP

🔌 Function

Takes up a measured amount of endfloat or clearance in an assembly, so the stack can be set to specification by selecting a thickness.

⚠️ Common Signs of Failure

• Endfloat or clearance measuring outside specification on assembly
• Shim found dished, bruised or picked up on strip-down
• Bright fretting marks on the shim faces
• Whine, knock or rumble traced to a slack stack
• Shim cracked or broken into pieces

🛠️ Service Notes

• Two 0.50 mm shims are listed here — check the engine family, not the thickness, to pick between this one and 978915
• Order shims by measured thickness rather than by weight; the published weights in this thickness range do not follow the thickness

📦 Condition
