Isuzu Clutch Disc 1-31240-739-0

Description

Isuzu Clutch Disc 1-31240-739-0 is a key component of a manual transmission clutch assembly. meaning it’s a genuine part originally fitted on certain Isuzu trucks and engines. .

How It Works

Inside a manual-shift vehicle’s clutch system:

1. The clutch disc sits between two parts:

   • The flywheel (attached to the engine)

   • The pressure plate (bolted to the flywheel)

2. When the clutch pedal is released, the pressure plate squeezes the clutch disc firmly against the flywheel.

   • This allows engine power to travel through the clutch disc into the transmission and then to the wheels.

3. When the clutch pedal is pressed, the pressure plate moves away and the clutch disc separates from the flywheel.

   • This stops power transfer so you can shift gears smoothly.

The friction material on the disc’s surfaces is what lets it grip the flywheel without slipping.

Key Points about 1-31240-739-0

• OEM Isuzu part number — meaning it’s a genuine original part designation.

• Used in manual-transmission Isuzu trucks, particularly some medium-duty models with diesel engines where this clutch disc matches the flywheel and pressure plate design.

• Often matched by aftermarket equivalents (e.g., from brands like EXEDY) that list this number as one of the compatible OEM references.

Why It Matters

The clutch disc is one of the main parts that wears out in a clutch assembly. Over time, the friction material thins, which can lead to:

• Slipping clutch (engine revs rise without corresponding speed increase)

• Poor acceleration

• Difficulty shifting gears

• Clutch chatter or vibration

Replacing the clutch disc when worn helps restore smooth gear changes and proper power transfer.
