🔧 Product Description

Genuine Volvo Penta shim 0.98 mm thick, from the Fuel System group and listed for 24 applications across the TWD, TID, TD, TAMD and TAD ranges. Thickness is the whole point of the part, as shims of this family are supplied in steps, so order by the stamped or measured thickness rather than by eye. It supersedes part number 6231520, catalogued earlier as an adjusting washer.

⚙️ Key Features

• 0.98 mm thick
• 24 applications across the TWD, TID, TD, TAMD and TAD ranges
• Supersedes 6231520, catalogued earlier as an adjusting washer
• Ordered by measured thickness

🔌 Function

Sets the working clearance or height of the assembly it is fitted under, by its measured thickness.

⚠️ Common Signs of Failure

• Pump or injection timing found outside its setting figure
• Hard starting, smoke or rough running traced back to a setting error
• Shim pitted, scored or dished on either face
• Shim measuring under its nominal thickness when checked with a micrometer

🛠️ Service Notes

• Measure the old shim with a micrometer and work out the change needed before ordering, since the steps in this family are finer than anything that can be judged by eye
• Fit one shim of the correct thickness rather than stacking thinner ones
• Supersedes 6231520, which was catalogued as an adjusting washer, so the old description will not match a search
