the bearing preload adjustment procedure. 
When repeating the procedure, rotate the 
inner spanner nut a little less during Step 
7 in the preceding instructions. 

NOTICE 

Do not over tighten the outer 
spanner nut because additional 
pressure can force the bearings 
even tighter against the races in 
the headstock and cause the 
headstock to compress, crack, or 
cause bearing failure.
