🔌 Function

Sets the final axial position of the bearing or shaft assembly so the specified preload or end float is achieved.

⚠️ Common Signs of Failure

• Gear or bearing whine after assembly
• Excessive shaft end play
• Bearing overheating from excessive preload
• Premature roller-bearing or seal failure
• Metal debris caused by incorrect shaft alignment

🛠️ 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
