17501823 Shim | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta shim is a selective-thickness adjustment component used in the dual-PTO lower-gear shaft end-float adjustment. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it provides one of the selective shim options used to set shaft/gear end float in the dual-PTO flywheel-housing lower-gear assembly. Selection must be confirmed by OEM part number 17501823, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1170-72VE

• Engine Family: TAD

⚙️ Key Features

• OEM Volvo Penta part number 17501823
• Thickness-specific component - other thicknesses are separate part numbers
• Fits TAD-series industrial diesel engines

🔌 Function

Provides one of the selective shim options used to set shaft/gear end float in the dual-PTO flywheel-housing lower-gear assembly. Measure the assembled clearance with calibrated tools and select the exact required thickness; never substitute by part-number sequence alone.

⚠️ Common Signs of Failure

• Measured clearance or endfloat outside the specified tolerance
• Visible wear, scoring or polishing on the shim faces
• Distortion or dishing from over-tightening
• Corrosion or pitting reducing effective thickness
• Repeat failure of the adjacent component from an incorrect clearance

🛠️ 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
