43-003 HYDRAULIC SAND PLOW INSTRUCTIONS

Assemble Pusher Bars (Ref # 22 and 25) to Plow Blade (Ref # 16) using one

-16 x 1 Bolt (Ref # 19) and

one

-16 x 3 Bolt (Ref #21) per Pusher Bar. There are 2 holes to bolt (Ref # 19) hardware in. Using hole closest

to the blade will result in a shallow cut, whereas using the hole furthest from the blade will result in a deeper cut.
The slot on the pusher bar is for a more fine tuned adjustment.

Assemble the Lift Assembly (Ref # 10) to the Main Frame using the two studs that are under the frame and
below the front of the console.

Place Cylinder Lift (Ref # 26) into the tube on Lift Assembly (Ref # 10) with the tab pointing up hold with a

-16 x

2 Bolt (Ref # 13), assemble the Valve Mount (Ref # 6) onto this bolt on the outside of the tube and secure both
with one

-16 Nut. Using a

-16 x 2 Bolt mount the Hydraulic Cylinder (Ref # 12) to the Lift Assembly and

secure with one

-16 Nut. Connect the other end of the Hydraulic Cylinder to the Cylinder Lift using ½ x 1½

Clevis Pin (Ref # 23) and

x 1 Cotter Pin (Ref #11).

Thread one ½ - 20 Jam Nut (Ref # 14) onto each Lift Rod (Ref # 15) followed by the Rod Ends (Ref # 9). Adjust to
equal lengths. Bolt Lift Rods to Lift Arms on Lift Assembly (Ref # 10) with Rod Ends to the outside. Bolt from
outside with the ½” Machine Bushing (Ref # 8) between Rod End and Lift Arm and secure with ½ -13 Lock Nut.

Slide the Plow/Pusher Bar Assembly under machine and connect to machine. Secure using ½ x 1½ Clevis Pins
(Ref # 23) and

" Bridge Pins (Ref # 24).

To connect Lift Rods (Ref # 15) to Pusher Bars start by lifting up the Plow Blade. Using one

-16 x 3 Bolt (Ref #

20) and two

" Washers assembly the Lift Rods to the Right (Ref #22) and Left (Ref # 25) Pusher Bars using

the bottom hole in the Lift Rods as illustrated. Secure each with one

-16 Lock Nut.

To fine tune the height of the blade off ground; turn the Rod Ends (Ref # 9) on the Lift Rods (Ref # 15). Turning
the Rod Ends counter-clockwise will increase down pressure. Turning them clockwise will decrease down
pressure.

Thread two of the 45° Elbow fittings (Ref # 2) into the Single Bank Valve (Ref # 5), one each in the A port, B port.
Thread two of the 90° Elbow fittings (Ref # 29) into the Single Bank Valve IN port and OUT port. Thread the
remaining two 45° (Ref # 2) Elbow fittings into the ports on the Hydraulic Cylinder (Ref # 12). Make sure the
fittings on the Hydraulic Cylinder are pointing towards the machine.

Connect the 57½" Hose (Ref # 31) to the inlet on the Single Bank Hydraulic Valve (Ref #5). Connect the 75"
Hose (Ref # 34) to the OUT port. Next connect the 18" Hose (Ref # 27) to the fitting in the B port and connect the
20" Hose (Ref # 28) to the fitting in the A port.

10.

Mount the Single Bank Hydraulic Valve (Ref # 5) to the Valve Mount (Ref # 6) as illustrated using the two ¼ - 20 x 2
Bolts (Ref # 4). Secure with the two ¼ - 20 Flange Whiz-Lock Nuts. Connect the Straight Handle Kit (Ref # 3) to
the Valve. Reference Single Bank Hydraulic Valve Drawing on page 6 for a detailed view of the Valve. The Single
Bank Valve is used in some other applications, therefore the handle housing may need to be reversed. Remove
the two screws holding the housing assembly onto the valve body, turn it over and reinstall the screws. The
handle must be pointing upward (reference drawing on page 44) when the valve is sitting on a table.

11.

Route the 18" Hose (Ref # 29) from the B port on the Single Bank Hydraulic Valve (Ref # 5) to the rear port on the
Hydraulic Cylinder. Route the 20" Hose (Ref # 30) from the A port on the Single Bank Hydraulic Valve to the front
port on the Cylinder.

12.

Disconnect the negative (-) ground battery cable from the battery. Place a drain pan under the valve on the
machine. ENGINE MUST BE COOL BEFORE DISCONNECTING THE HOSES.

13.

Disconnect the hose from the T port on the 2 Bank Valve (Ref # 32) and the top port on the Oil Cooler. Discard
this hose, it will not be used. Connect the 75" Hose (Ref # 34) from the T port on the Single Bank Valve to the top
port on the Oil Cooler. This hose may be a bit long on the Gasoline Models so you may have to loop the hose
around the back of the pump to use up some hose. Connect the 57½" Hose (Ref # 31) from the P port of the
Single Bank Valve to the T port of the 2 Bank Valve. Tie up Hoses using

Loom Clamp (Ref # 28). Route the

57½" & 75" Hoses under the body and along the frame avoiding any pinch points. Fasten to the frame using the
14½" Nylon Ties.

14.

Reconnect the negative (-) ground battery cable to battery.

15.

Make sure that everything is clear of the machine. Start the machine, work the valve so that the plow will both
raise and lower. Also, do this with both the attachment lift and the rake lift. Work the lift a number of times until all
air works out of the plow circuit and the cylinder works smoothly. At this time look for hydraulic leaks. If there are
leaks, turn engine off and repair, start up and check again.

16.

Check the hydraulic oil level. The level should be 2” to 2½” below the top of the tank. If more is
needed, use SAE 10W-40 API service SG motor oil.
