Assembling the GFA Module
To assemble the GFA module:
1.
Grease the inside of the idler gears and place over the shafts.
2.
Repeat for all idler gears. The number of idler gears depend on the configuration of the GFA module.
3.
Insert the needle roller bearings. Make sure to insert as many needle roller bearings as there is
space for. There should not be any gaps.
4.
Make sure that the parallel pin is inserted.
5.
Apply grease to the idler gears.
6.
Apply grease to the socket gear and place it in the housing. Make sure to place it in the right direc-
tion, according to the specification.
7.
Place the upper part of the housing on top of the lower part. Use a press tool and press evenly over
the housing.
8.
Make sure that there is no gap between the upper and lower parts of the housing.
9.
Grease the inside of the input gear and the needle carrier. Place the needle carrier in the input gear.
10. Use a press tool to push the ball bearing onto the input gear. Use a cylinder with the correct mea-
surements to make the ball bearing go all the way down.
11. Insert the input gear into the bearing housing.
12. Place the nut over the bearing housing.
13. Place the cover plate on the collar back latch. Grease the pawl and spring and insert into the collar
back latch.
The collar back latch can include a torque arm flange depending on the configuration.
14. Push in the pawl and put the collar back latch over the bearing housing. The pawl should go into one
of the two grooves of the input gear. Depending on the gear stage and the desired rotational direc-
tion, the collar back latch can be placed either with the cover plate facing downwards (A) or upwards
(B).

15. Turn the input square all the way to locked position. Make sure that the output gear is in open posi-
tion and insert the input gear into the housing. The teeth of the gears should mesh. Push the input
gear all the way down until the input gear is flush with the housing. Make sure that the output gear is
in open position when the input gear is in locked position.
16. Secure the housing in a vice and insert the cover cap into the housing. Push the input gear up from
below while tightening the cover cap.
17. Tighten the screws.
18. Use a grease gun to fill the housing with grease through the grease nipple. Note that the GFA mod-
ule can have a different amount of grease nipples depending on the model.
19. Screw the adapter onto the bearing housing until it stops. Secure the housing in a vice and tighten
the nut.
