STEP 1  POSITIONING & MOUNTING

 

The Model SS675 is designed to mount behind the truck cab across the frame rail sides. 

 

A)  Diagram A describes two mounting options available. Allow a minimum of 4” on both sides 

of the unit for proper airflow.

 

 

 

STEP 2  INSTALLING THE PTO & HYDRAULIC PUMP
 

 

A)  Install the PTO to the transmission and mount the hydraulic pump according to 

 

 

     the instructions included with the PTO.

 

 

HELPFUL HINT

:  

If you are using a direct mount hydraulic pump/PTO combination,  

 

 

be sure that the pump splines are well lubrication with a heavy grease.  This grease  

 

 

will prevent premature spline wear on the PTO and pump shafts.  A small packet of  

 

 

this grease is available through STAC Inc P/N 300980.  Also available from both  

 

 

MUNCIE and CHELSEA is a new option for a greaseable shaft.  This option allows  

 

 

you to grease these splines without pulling the pump off the PTO.
