Installation notes
Check before installation that the bearing seat on the shaft and in the housing is free from burrs and damage. The bearing must be pressed with even pressure on the outer ring. Ensure correct orientation of the shield (Z-side). Lubricate the bearing if necessary before installation with suitable transmission oil or grease.
Compatibility

Note the difference between 6307Z (single shield), 6307ZZ (double shield), 6307N (with snap ring groove) and other variants - verify the original specification of your transmission.
Historical context
