Finish machining of stem nut (output drive type A):

The output drive flange does not have to be removed from the actuator.

Remove spigot ring (80.2, figure C-1) from mounting flange.

Take off stem nut (80.3) together with thrust bearing (80.01) and thrust bear-

ing races (80.02).

Remove thrust bearing and thrust bearing races from stem nut.

Drill and bore stem nut and cut thread.

When fixing in the chuck, make sure stem nut runs true!

Clean the machined stem nut.

Apply Lithium soap EP multi-purpose grease to thrust bearing and races, then

place them on stem nut.

Re-insert stem nut with thrust bearings into the mounting flange. Ensure that

dogs are placed correctly in the slots of the hollow shaft.

Screw in spigot ring until it is firm against the shoulder.

Press Lithium soap EP multi-purpose grease on mineral oil base into the

grease nipple with a grease gun (for quantities, please refer to table):
