III. Fixing and unfixing of output shaft 
Note: do not try repairing the output shaft but replace the assembly as a whole. Please 
replace the output shaft assembly if 1-2 synchronizers or gears have troubles.  
If the synchronizer’s synchronizing ring clearance is to be checked, please measure the 
clearance between the synchronizer and the transmission gear with a clearance gauge. 
The nominal values are:  
• 1st gear - 0.522-2.208 mm (0.021-0.087 in) 
• 2

nd

 gear - 0.522-2.208 mm (0.021-0.087 in) 

• 3

rd

 gear - 0.73-1.53 mm (0.029-0.060 in) 

• 4

th

 gear - 0.77-1.57 mm (0.030-0.062 in). 

• 5

th

 gear - 0.73-1.53 mm (0.029-0.060 in) 

Any synchronizing ring whose clearance does not comply with the above criteria must be 
replaced. If the abrasion of 1

st

 and 2

nd

-gear synchronizer’s synchronizing ring goes 

beyond the criteria, the output shaft assembly must be replaced (Figure 134).
