5th gear synchronizer (Hyundai Elantra J2)

Examination

Clutch and synchronizer hub

1. Connect the coupling and the synchronizer hub and make sure that they slide smoothly against each other.

2. Check for damage.

3. Check for wear on the front surface of the hub (surface in contact with the fifth gear wheel).

Warning. Replace the hub and synchronizer sleeve as a set.

Cracker and synchronizer spring

1. Check the wear of the central protrusion of the synchronizer cracker.

2. Check the spring for weakening, deformation and breakage.

Assembly

1. Assemble the hub, clutch and synchronizer crackers, paying attention to their location.



2. There are missing teeth in six places around the circumference of the synchronizer clutch.



Install the coupling on the hub so that the coupling tooth located between the two missing teeth contacts the synchronizer cracker.



3. Install the synchronizer springs so that their protrusions interact with the grooves of the synchronizer crackers.

Warning. When installing the synchronizer springs, make sure that the front and rear springs are not positioned in the same direction.
