Before removing position indicator (1-220), record or mark its position. Remove 
position indicator (1-220).

NOTE:  

Step 2.3.4 is used only on G01, G2 and G3 drive modules. Drive modules G4 through G10 
will skip steps 2.3.4 and continue with step 2.3.5.

2�3�4 

Remove one vent check assembly (13) from top of housing cover (1-20).

2�3�5 

Unscrew and remove hex cap screws (1-160) with lockwashers (1-170) from yoke 

cover (1-150).

2�3�6 

Remove yoke cover (1-150) from housing cover (1-20).

2�3�7 

Mark and record the orientation of the position indicator assembly (1-140) in 
relation to the top of yoke (1-70).

2�3�8 

Remove position indicator assembly (1-140) from top of yoke (1-70).

2�3�9 

Remove spring pin (1-100) from top of yoke (1-70).

2�3�10 

Remove hex cap screws (1-110), with lockwashers (1-115) or with lockwashers 

 

(1-170), from housing cover (1-20).

NOTE:  

Steps 2.3.11 and 2.3.12 are used only on G7, G8 and G10 Drive Modules. Drive modules 
G01, G2, G3, G4 and G5 will skip steps 2.3.11 and 2.3.12 and continue with step 2.3.13.

2�3�11 

Remove hex cap screws (1-120), with lockwashers (1-115), from housing cover (1-20).

2�3�12 

Using hex cap screws (1-110), install into holes vacated by hex cap screws (1-120). 
Use these hex cap screws to jack the housing cover up for removal. Alternately rotate 
the hex cap screw clockwise until housing cover (1-20) is clear of housing (1-10).

NOTE:  

G01, G2, G3 and G4 model housing cover (1-20) will have cast tabs for placing prying tools 
to aid in cover removal.

2�3�13 

Remove housing cover (1-20) from housing (1-10).

NOTE:  

Groove pins (1-130) will remain in housing cover (1-20) when housing cover is removed 
from housing (1-10). Groove pins (1-130) should not be removed from housing cover  
(1-20) unless they are damaged and require new replacements.

2�3�14 

Refer to assembly drawing page 2 of 2 Detail "B". Remove guide bar (1-90) from
