Prior to removing the steering pump, it is necessary to
remove the fender assembly.
CAUTION: Slowly remove the hydraulic lines from the
hydraulic steering pump. Test for pressure in the lines
before removal.
1. Place an oil pan directly under the hydraulic
steering pump. This will catch the hydraulic fluid
that will be drained from the lines and the pump.
2. Remove all four of the hex head tapp screws from
the drive shaft to the pump adapter using a 3/8
socket.
NOTE: Removal of the drive shaft from the pump
adapter is necessary to allow access to the four
hydraulic steering pump mounting bolts.

9. Remove the port plate from the hydraulic lines.
NOTE: Pivot the top edge of the port plate
backward (towards the left frame rail), bringing
the plate to horizontal. Push the port plate up and
rotate the port plate counter-clockwise 90
degrees using the main pressure line as the pivot
point. Slide the port plate towards the left frame
rail until the port plate clears the hydraulic lines.
