NISSAN 32202-B950A Input Shaft Pilot Bushing

The genuine NISSAN (SKU: 32202-B950A) input shaft pilot bushing (OEM designation: BUSHING GEAR or pilot bushing) is a critical precision component in the vehicle drivetrain. This bushing ensures precise centering and stable support for the transmission input shaft inside the end of the engine crankshaft or the flywheel.

Function and Operating Principle

The primary function of the input shaft bushing is to minimize radial play in the input shaft while accommodating the rotational speed difference between the crankshaft and the input shaft when the clutch pedal is depressed (disengaged). A precise fit is essential for proper clutch operation and to relieve mechanical stress on the transmission internal bearings.

Technical Specifications and Material Quality

Manufactured to the strict tolerances characteristic of genuine Nissan parts, this bushing provides outstanding wear resistance and thermal conductivity. It is typically produced from self-lubricating sintered bronze or a specialized alloy, ensuring durable and maintenance-free operation even under severe mechanical loads.

• Manufacturer: NISSAN OEM
• Part Type: Input Shaft Bushing (Bushing Gear / Pilot Bushing)
• Material: Premium self-lubricating bronze alloy for minimal friction
• Installation Location: Crankshaft bore / Flywheel pilot bore

Common Symptoms of Wear or Failure

Wear of the input shaft pilot bushing can trigger a chain reaction of wear throughout the drivetrain. A worn bushing may produce the following symptoms:

• Abnormal squealing or growling noise when the clutch pedal is depressed (when the crankshaft and input shaft rotate at different speeds).
• Difficult gear shifting, especially when engaging gear from a standstill.
• Clutch judder or vibration when starting off.
• Premature failure of the transmission input shaft seal, resulting in oil leaks.

Whenever replacing the clutch assembly or the flywheel, replacement of the input shaft pilot bushing is strongly recommended to prevent future issues.
