11705737 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta adjusting washer for the fuel system, supplied in the 1.70 mm thickness (TH=1,70mm). Shims like this are used to set the correct clearance or preload within the fuel injection assembly, so selecting the exact thickness is essential - siblings of this part carry identical names but different thicknesses. It fits a wide span of Volvo Penta 2000-series, 30-series and 40-series marine diesel engines.

🚤 Compatibility

• Engine Family: TAMD, AD, TMD, KAD, KAMD
• HP Range: Approximately 7.5-300 HP
• Year Range: Approximately mid-1970s - 2005

🔌 Function

The adjusting washer acts as a calibrated shim that sets the correct clearance, height or preload in the fuel injection assembly. Its specific thickness determines the resulting adjustment, so it must match the setting called for during service.

⚠️ Common Signs of Failure

• Visible wear, scoring or pitting on the contact faces
• Deformation or flattening that reduces effective thickness
• Fuel weeping or leakage at the sealing or seating surface
• Injection timing or delivery out of specification during setup
• Rough running, hard starting or uneven cylinder performance after a fuel system rebuild

🛠️ Service Notes

• An adjusting washer is a precision-thickness shim: the correct one is whichever thickness gives the dimension called for in the workshop manual, so it is chosen by measurement rather than by simply matching what came out
• Measure the washer itself with a micrometer before fitting — thickness is the whole function, and markings or part numbers are no substitute for a measured figure
• Do not reuse a washer that is dished, indented, scored or corroded; a shim that has been distorted under clamp load will not restore the original setting
• Clean the seat and the washer of oil, old sealant and burrs so the stack sits dead flat — a trapped burr is thicker than the tolerance you are shimming to
• Where washers are refitted rather than renewed, keep each one with the component and position it came from, and record the thickness used so the setting can be reproduced later
