34-149 HYDRAULIC SAND PLOW INSTRUCTION
(FACTORY INSTALLED)
1. Bolt bracket (Ref 21), to the bolts welded in the bottom of the main frame. Use 3 /
8
washer and lock nut (Ref 20) to
hold in place.
2. Fasten pusher bars (Ref 3 and 12) to the sand plow (Ref 4), as shown. Leave loose.
3. Fasten lift bar (Ref 5) to the pusher bars, as shown. Leave loose.
4. Put the plow in front of the trap rake and slide it back so that the pusher bars can be connected to the tabs on the
frame with clevis pin and bridge pin (Ref 13).
5. Tighten the bolts and nuts holding the left bar to the pusher bars.
6. Set the plow at the desired angle and tighten the bolts and nuts holding it to the pusher bars.
7. Attach the hydraulic cylinder to the cylinder bracket with the 5 /
8
x 1 3 /
4
clevis pin and one 1 /
8
bridge pin. The ports on the
cylinder must point to the right side of the machine.
8. Thread the jam nut and the rod end onto the cylinder rod end and leave them loose to find the required length.
9. Either extend the rod or raise the plow up and fasten them together with 1 /
2
x 2 clevis pin and 1 /
8
bridge pin (Ref 6).
Place oilite bushing (Ref 15) in rod end and slide clevis pin through.
10. Remove the handles from the 2-bank valve and put them on the 3-bank valve. The extra handle shipped with the plow
goes on the outside.
11. Mark the hoses on the 2-bank valve that is on the machine so that they can be put in the same position on the 3-bank
valve.
12. Disconnect the negative (-) ground battery cable from the battery. Place a drain pan under the valve in the machine. Be
sure engine is cool before disconnecting the hoses. Remove the 2-bank valve.
13. Remove the fittings from the 2-bank valve and put them into the 3-bank valve (with the outside bank for the sand plow).
Put the 16-169 adapters in first and then the 18-168 elbows and the 18-202 elbow.
14. Put the 3-bank valve into the machine and reconnect the hoses. The outside bank is for the sand plow; middle bank is
the rake lift; the inside bank is for the attachment lift.
15. Drill a 3 /
8
diameter hole in the right floorboard , 12 inches from the rear edge and 3 1 /
2
inches down from the top.
16. Connect the two hoses to the cylinder using the ridge end first. Route the hose along the right floorboard and in front of
battery up to the valve being careful to leave clearance by moving parts. Tighten all fittings.
17. Secure the two hoses to the inside of the right floorboard using 13-099 hose clamp. Place the 5 /
16
- 18 x 1 1 /
2
truss
machine screw through the hole you drilled with one hose on each side of the screw. Place the hose strap over the
screw and hoses, tighten
5 /
16 - 18 lock nut.
18. Reconnect the negative (-) ground battery cable to battery.
19. 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.
20. Double check all fasteners and fittings, be sure they are tight.
21. Check the hydraulic oil level. The level should be 2” to 2 1 /
2 ” from the top of the tank. If more is needed, use SAE 10W-
40 API service SJ or higher motor oil.
