11700454 Shim | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta shim in the 1.70 mm thickness, part of the fuel system group on TAD520VE and TAD720VE engines. Shims are supplied in graded thicknesses so the correct one must be selected for the required setting - this item is the TH=1.70 mm size. Fitting the wrong thickness will alter the clearance or timing it is meant to control.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD720VE
• Volvo Penta TAD520VE

• Engine Family: TAD
• HP Range: Approximately 160-300 HP
• Year Range: Engine family introduced from 2001; final fitment is controlled by engine model, specification number, injector number and measured calibration requirement

⚙️ Key Features

• OEM Volvo Penta part number 11700454
• Thickness: 1.70 mm (TH=1,70mm)
• System group: Fuel System
• Fits TAD-series industrial diesel engines (TAD520VE, TAD720VE)
• Supplied as an individual shim - thickness must match the specified setting
• Engine type: Volvo Penta 4-cylinder and 6-cylinder turbocharged, direct-injected industrial diesel with individual unit pumps and mechanical injectors

🔌 Function

The shim acts as a precision spacer within the fuel system assembly, setting the correct clearance or height between mating components. Its graded thickness allows the installer to bring the assembly within the specified tolerance during fitting or overhaul.

⚠️ Common Signs of Failure

• Measured clearance or height outside the specified tolerance during service checks
• Visible wear, scoring or deformation on the shim faces
• Rough running, hard starting or poor fuel delivery traced to an incorrect shim thickness
• Fretting or pitting where the shim contacts the mating surfaces
• Component looseness or movement indicating the shim has worn or was mis-sized

🛠️ Service Notes

• Shims are supplied in graded thicknesses and exist to bring a setting into specification, so measure with a micrometer and select the thickness the setting procedure for your engine calls for rather than matching one by eye
• Note which shim came from which position on removal and keep them identified — once an assembly has bedded in, shims are not interchangeable between positions
• Check both faces are clean, flat and free of burrs, corrosion and old sealant before fitting; dirt trapped under a shim shifts the setting as surely as the wrong thickness does
• Discard any shim that is dished, cracked, pitted or fretted rather than reusing it, and make sure no old shim has been left behind in the recess
• Recheck the clearance or setting after the assembly is tightened down, because clamping load can change the measurement you took loose
