AE92 Nachi Self-Aligning Clutch Release Bearing (1987-91 Corolla Coupe)

Nachi Self-Aligning Clutch Release Bearing

For 1987–1991 Toyota Corolla AE92 coupes equipped with naturally aspirated engines and five-speed manual transmissions.

Overview

This Nachi self-aligning clutch release bearing and hub assembly transfers force from the release fork to the rotating clutch during disengagement. It is offered for 1987–1991 Toyota Corolla AE92 coupes with naturally aspirated 4A-GE, 4A-F or 4A-FE engines and five-speed manual transmissions.

The two fork-guide spans, 70.15 mm and 79.2 mm, match different original release-fork arrangements while sharing the same 33 mm bore. The installed bearing's fork-guide span and matching original fork determine the correct option, not model year or transmission code alone. May 1991 production overlaps both arrangements.

Key Features

• Self-aligning bearing design for the matching diaphragm-spring clutch.
• Combined bearing and release hub supplied as one assembly, separately from a complete clutch kit.
• Outside fork-guide arrangement in two different fork-guide spans.
• Shared bearing dimensions of 33 mm bore, 50 mm contact diameter and 22 mm fork-to-contact width.

Vehicle Fitment

79.2 mm Fork-Guide Span — Original Wider Release Arrangement

• 1991: Levin / Trueno (JDM) / Naturally aspirated 4A-GE / Production May 1991–June 1991
• 1991: GT-S (U.S.-Market) / 4A-GE / Production May 1991–June 1991 / Matching late release fork
• 1991: SR5 (U.S.-Market) / 4A-FE / Production May 1991–June 1991 / Matching late release fork

U.S. year ranges are model years; production ranges refer to vehicle build dates. May 1991 overlaps the two release arrangements, so the original bearing and fork determine the correct span.

Fitment Notes

• Does not fit factory supercharged 4A-GZE release assemblies or automatic transmissions.
• The 70.15 mm and 79.2 mm spans describe the fork-guide width, not bearing bore or outside diameter. They are not interchangeable with the same release fork.
• Engine/transmission conversions or altered clutch-release hardware must match the fitted bearing, hub and fork; the vehicle's year alone is not sufficient.
