Synchronizer Rings
- Do not interchange them. When reusing synchronizer rings, always install on the same gear wheel.
- Check for wear and replace if necessary.
- Check the grooves -arrow 1- on the synchronizer ring -A- and the inner race for flat areas (grooves are worn).
- The coating on the synchronizer rings must not be damaged.
- If an intermediate ring -B- is installed, check this intermediate ring on the outer friction surface -arrow 2- and inner friction surface -arrow 3- for »grooves«, »wear grooves« and »blue coloring (from overheating)«.
- Check taper of drive gear for »grooves« and »scoring«.
- Coat the synchronizing with transmission fluid and then install.
