43-003 HYDRAULIC SAND PLOW INSTRUCTIONS
1. Assemble Pusher Bars (Ref # 22 and 25) to Plow Blade (Ref # 16) using one 3 /
8
-16 x 1 Bolt (Ref # 19) and
one 3 /
8
-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.
2. 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.
3. Place Cylinder Lift (Ref # 26) into the tube on Lift Assembly (Ref # 10) with the tab pointing up hold with a
3 /
8
-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 3 /
8
-16 Nut. Using a 3 /
8
-16 x 2 Bolt mount the Hydraulic Cylinder (Ref # 12) to the Lift
Assembly and secure with one 3 /
8
-16 Nut. Connect the other end of the Hydraulic Cylinder to the Cylinder
Lift using ½ x 1½ Clevis Pin (Ref # 23) and 1 /
8
x 1 Cotter Pin (Ref #11).
4. 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 spacer (Ref # 8) between Rod End and Lift Arm and secure with ½ -13
Lock Nut.
5. Slide the Plow/Pusher Bar Assembly under machine and connect to machine. Secure using ½ x 1½
Clevis Pins (Ref # 23) and 1 /
8
" Bridge Pins (Ref # 24).
6. To connect Lift Rods (Ref # 15) to Pusher Bars start by lifting up the Plow Blade. Using one 3 /
8
-16 x 3
Bolt (Ref # 20) and two 3 /
8
" 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 3 /
8
-16 Lock Nut.
7. 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 de-
crease down pressure.
8. Thread four of the 45° Elbow fittings (Ref # 2) into the Single Bank Valve (Ref # 5), one each in the A port,
B port, IN port and OUT port. Thread the remaining two 45° Elbow fittings into the ports on the Hydraulic
Cylinder (Ref # 12). Make sure the fittings on the Hydraulic Cylinder are pointing towards the machine.
9. Connect the 57½" Hoses (Ref # 31) to the fittings on the Single Bank Hydraulic Valve (Ref #5). One to the
IN port and one 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.
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 OUT 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 57½" Hose (Ref # 31 a ) from the OUT port on the Single
Bank Valve to the top port on the Oil Cooler. Connect the other 57½" Hose (Ref # 31 b ) from the IN port of
the Single Bank Valve to the OUT port of the 2 Bank Valve. Tie up Hoses using 5 /
8
Loom Clamp (Ref #
28). Route 57½" 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.
