SYNCHRO SLEEVE AND HUB INSPECTION AND REASSEMBLY

2008 Honda Civic LX

2006-08 TRANSMISSION Manual Transmission (6-Speed)(Except Hybrid) - Civic

1. Inspect gear teeth on all synchro hubs and synchro sleeves for rounded off

corners, which indicate wear.

2. Install each synchro hub (A) in its mating synchro sleeve (B), and check for

free movement. Make sure to match the three sets of longer teeth (C) (120
degrees apart) on the synchro sleeve with the three sets of deeper grooves (D)
in the synchro hub.

NOTE:

Do not install the synchro sleeve with its longer
teeth in the synchro hub slots (E) because it will
damage the spring ring.

If replacement is required, always replace the
synchro sleeve and synchro hub as a set.

4. Inspect the cone surface (B) on each gear hub for wear and roughness.
5. Inspect the teeth on all gears (C) for uneven wear, scoring, and cracks.
6. Coat the cone surface of each gear with manual transmission fluid (MTF), and

place its synchro ring on it. Rotate the synchro ring, making sure that it does
not slip.

7. Measure the clearance between each gear (A) and its synchro ring (B) all

around the gear. Hold the synchro ring against the gear evenly while measuring
the clearance. If the clearance is less than the service limit, replace the synchro
ring and gear.
