9. Assembly of driving chain
The parts assembly process is as follows:
(a) Put the driving chain sprocket at the rear end of the output
shaft, and the driven chain sprocket is put at the rear end
of the front output shaft on the worktable after the transfer
box housing assembly mount.
(b) Mount the chain on the sprocket.
(c) Holding the two chain sprockets parallel with the transfer
box in the space that the chain on the two sprockets are
straightened, and encase the chain and sprocket assembly
through the output shaft, it is required to run the chain
sprocket slowly to ensure that they engage with the front
output shaft and the spline.
(d) Mount the gasket and snapping ring on the front output
shaft.
10. Shift locking element assembly
The parts mounting process is as follows (for the electric shift
transfer box):
(a) Mount the return spring and locking hub on the locking
sleeve and fasten them with snapping ring to finish the
2W-4W locking sleeve assembly.
(b) Encase the shift guide shaft in the blind hole of the
housing through the deceleration toggle fork assembly
that is already assembled.
(c) Mount the shift toggle fork on the 2W-4W locking sleeve
assembly, which will slide through the shift guide shaft
and rear output shaft.
(d) Joint the combined external gear sleeve spline and the
rear output shaft spline as well as the 2W-4W locking
sleeve.
