gun and pump lithium grease (about 10 g) into 
the lubricating hole of the gearbox until old

grease exits into the cavity of the outer tube. 
Remove excess grease and put the gearbox 
housing into the outer tube. Make sure that the 
index screw is snapped into the outer tube lock. 
Tighten both screws.
