Bearing Sleeve

Discussion: Clutch Problems

For A-series engines, there are two lengths. One is 4.5 mm longer.

For use with A12 Flywheel on A14 engine, use the longer Sleeve:

Or make your own longer sleeve:

Or just use the A14/A15 flywheel. People like the A12 flywheel because it is lighter, but you can lighten the A14 type.[quote]Does the flywheel really make a difference?[/quote]
