INSTALL DRIVE COLLAR
Procedure is similar to install a drive
collar at the forward or aft head.
Clean splines (1) of drive collar (2) and splines
(3) of drive shaft (4). Use cloth (E120) damp with
toluene (E423). Wear gloves (E184.1).
Apply a thick coat of grease (E190) to splines
(1 and 3). Use brush (E86). Make sure spline
grooves are full of grease.
Align master splines (5 and 6) of drive collar (2)
and drive shaft (4). Slide the collar onto the shaft.
Wipe off excess grease with cloth (E120).
Connect upper drive arm (7) to drive collar (2).
Check clearance at drive arm lugs (Task 5-112).
