Snowplow Assembly Procedure 

 

 

Figure 7.

 Assembly of Hydraulic Connections. 

G10013 

 
24.  Attach one end of Hydraulic Hose (49) to the 

lower port of Lift Cylinder (42).

 

 Attach the 

opposite end of Hydraulic Hose (49) to the center 
Hydraulic Fitting (54). Tighten connection 
securely. 

 
25.  Apply thread sealant compound (do not use 

Teflon Tape) to the threads of the 3/8” MNPT end 
of 

HYD07042 

Hydraulic Hose (52). Thread the 

hose into the port on Angle Cylinder (40) and 
tighten securely.

 

 

Note:

  Do not apply thread compound to the ¼” end of 

the hose. 

 
Note:

  Do not get thread compound on the end of the 

hose since the compound will contaminate the 
hydraulic system. 

 

26.  Attach the loose end of 

HYD07042

 Hydraulic 

Angle Hose (52) to the corresponding fitting on 
the hydraulic manifold. Tighten all hydraulic 
connections securely. 

 

Figure 8.

 Light Bar Assembly. (Standard) 

G10132 

 
27.  Attach Light Bar (13) to the top of Coupler 

Assembly (1) using two Hex Head Cap Screws 
(91) and Hex Head Self Locking Nuts (109). 

 

Note:

  The light bar should be positioned as close to 

the Coupler Tower as possible. Only two holes will be 
aligned for normal installations. Only two bolts per side 
are needed to secure the light bar. 

 

Figure 9. 

Light Bar Assembly Adjustment. 

G10131 

 

Note:

  Figure 9 illustrates that the Coupler Assembly 

and Light Bar have two sets of 1 inch adjustment holes 
for mounting on different vehicles. These adjustment 
holes may be needed in order to move the light bar 
away from the vehicle’s hood.
