11705731 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta adjusting washer from the fuel system group, supplied in the 1.50 mm thickness. Adjusting washers of this type are used as calibrated shims to set the correct clearance or height within the fuel injection assembly, so the stated thickness is the key detail that separates this washer from otherwise identical siblings. It supersedes earlier part number 243477 and is used across the 2001/2002/2003, AD31, AD41, TMD31, TAMD31, TAMD41, TAMD42 and KAD/KAMD42-43 engine families.

🚤 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 precision shim within the fuel injection system, setting the correct clearance, preload or protrusion height during assembly. Selecting the appropriate thickness allows the injection components to be brought to the specified factory tolerance.

⚠️ Common Signs of Failure

• Incorrect injection timing or fuel delivery after component replacement when the wrong shim thickness is fitted
• Fuel weeping or leakage at the sealing face caused by a worn, dished or damaged washer
• Visible flattening, scoring or reduced measured thickness on removal
• Corrosion or pitting on the washer faces preventing a clean seal
• Rough running, hard starting or reduced power traceable to out-of-specification injection clearance

🛠️ 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
