NISSAN 38153-82112 Adjusting Washer

The genuine Nissan (SKU: 38153-82112) adjusting washer (WASHER-ADJUST) is a precision-engineered fastening and adjustment component manufactured to strict tolerances. Its primary purpose is the precise setting and compensation of axial end play across various mechanical assemblies, particularly differentials, manual/automatic transmissions, and shaft connections.

Technical Features and Functions

• Premium Material Quality: Manufactured from high-strength hardened steel engineered to withstand continuous mechanical stress, elevated operating temperatures, and friction.
• Precision Thickness: Micrometer-accurate manufacturing ensures the optimal clearance setting between gears and bearings, preventing unwanted backlash.
• Wear Resistance: Treated with a specialized surface finish to prevent corrosion and premature component wear.

Why is using the correct adjusting washer important?

Within automotive drivetrain systems, tolerances measured in tenths of a millimeter can cause severe operational malfunctions. Incorrect shimming or clearance adjustment can lead to improper gear meshing (altered contact pattern), premature bearing failure, and elevated noise and vibration levels. The genuine Nissan adjusting washer ensures an exact fit to factory specifications and promotes drivetrain longevity.

Symptoms of Wear or Incorrect Adjustment

• Metallic, whining, or humming noises emanating from the differential or transmission, particularly under acceleration or engine braking.
• Increased drivetrain vibration.
• Abnormal or uneven contact wear patterns observed on gear teeth during inspection and maintenance.
