Synchronizer
Check items below. If necessary, replace them with new ones.
●Damage and excessive wear of contact surfaces of coupling
sleeve, synchronizer hub, and shifting insert
●Coupling sleeve and synchronizer hub must move smoothly.
●If any crack, damage, or excessive wear is found on cam face of
baulk ring or working face of insert, replace it.
Baulk ring clearance
●Press baulk ring against cone, and measure clearance between
baulk ring and cone. If measurement is below limit, replace it
with a new one.
Bearing
Check items below. If necessary, replace them with new ones.
●Damage and rough rotation of bearing
