1

Remove transmission bracket screws  (4) from transmission bracket  (3).

2

Support transfer case using telescopic lifter and transmission plate.

3

Unscrew rear engine mount nuts  (2) and screws of transmission bracket  (1), remove transmission bracket  (3).

4.1

If the articulation angle of the transfer case relative to the front of the rear propeller shaft  ( K3) should be larger.
Fabricate transmission bracket spacers  (6) with required thickness by means of geometry of transmission bracket  (3).      

 For each 3 mm sheet thickness, the articulation angle of the transfer case relative to the front of the rear propeller shaft  ( K3) becomes approx. 0.20 larger. During this the:
 articulation angle of the front axle differential relative to the front propeller shaft  ( K1) increases by approx. 0.3°;
 the articulation angle of the front propeller shaft relative to the transfer case  ( K2) decreases by approx. 0.33°;
 and the articulation angle at the front of the rear propeller shaft relative to the rear of the rear propeller shaft  ( K4) decreases by approx. 0.2°.

 With a spacer thickness of more than 2  mm, the screw length of the screws of the transmission bracket  (1) must be extended by 5  mm.

 If spacers more than 5 mm thick are required, the front and rear engine mounts must be checked for signs of settling or wear and be replaced if necessary.

4.2

If the articulation angle of the front axle differential relative to the front of the rear propeller shaft  ( K1) should be smaller.
Fabricate rear engine mount spacer  (7) by means of geometry of transmission bracket  (3).      

 For a spacer thickness of more than 2  mm, the screw length for the screws of the rear engine mount nuts  (2) must be extended by 5  mm.

 If a spacer more than 5 mm thick is required, the front and rear engine mounts must be checked for signs of settling or wear and be replaced if necessary.

 For each 3  mm sheet thickness, the articulation angle of the transfer case relative to the front of the rear propeller shaft  ( K3) is reduced by approx. 0.20. During this the:
 articulation angle of the front axle differential relative to the front propeller shaft  ( K1) decreases by approx. 0.3°;
 the articulation angle of the front propeller shaft relative to the transfer case  ( K2) increases by approx. 0.33°;
 and the articulation angle at the front of the rear propeller shaft relative to the rear of the rear propeller shaft  ( K4) increases by approx. 0.2°.

5

Insert transmission bracket spacers  (6) between frame floor assembly and transmission bracket  (3) or rear engine mount spacer  (7) between rear engine mount and transmission bracket  (3) and install transmission bracket  (3). Tighten transmission bracket screws  (1) and rear engine mount nuts  (2)   .
