11711243 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta adjusting washer for the fuel system, supplied in the 1.84 mm thickness (TH=1,84mm). Adjusting washers of this type are used as calibrated shims to set the correct clearance or preload within fuel system components, so the exact thickness must be matched to the specification called for during assembly or adjustment. It supersedes the earlier 1.85 mm washer, part number 870274.

🚤 Compatibility

• Engine Family: TWD, TID, TD, TAMD, TAD
• HP Range: Approximately 300-700 HP
• Year Range: Approximately 1970s - early 2000s

🔌 Function

The adjusting washer acts as a precision shim that sets a specified clearance or preload within a fuel system assembly. Its exact thickness determines the final adjustment, so it is selected to suit the measured requirement during service.

⚠️ Common Signs of Failure

• Incorrect clearance or adjustment measured during fuel system service
• Visible wear, scoring or dishing on the washer faces
• Deformation or cracking from over-tightening or vibration
• Corrosion or pitting causing loss of effective thickness
• Loss of setting or component play developing after reassembly with a worn washer

🛠️ 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
