Clutch Release Bearing 1-31310012-0 / 1-87610110-0 for ISUZU ELF 4HK1 — OEM Clutch Release Bearing Assembly

The Clutch Release Bearing Assembly with OEM reference numbers 1-31310012-0 and 1-87610110-0 is a verified direct-fit replacement for the ISUZU ELF series trucks equipped with the 4HK1 engine. This bearing is a critical component of the clutch system, mounted between the clutch and the transmission to engage and disengage the clutch.

When the clutch pedal is depressed, the release bearing moves along the transmission input shaft to press against the clutch pressure plate's diaphragm spring, disengaging the clutch and allowing for smooth gear changes. A worn or failing release bearing can cause noise when engaging the clutch, difficulty shifting gears, vibration, and eventual clutch failure.

This OE‑spec replacement bearing assembly restores factory clutch performance and smooth operation. Manufactured to meet or exceed original equipment standards, this assembly delivers reliable and consistent clutch disengagement for your ISUZU ELF truck.
