SNOWPLOW ASSEMBLY
8.
Attach the main frame to the A frame using the two frame pins (7, fig 12). Lock
the pins into the A frame with an M8 x 52 mm gr.8 hex head bolt (42, fig 12)
inserted through an 8 mm washer, then the top of the frame at each end and
secured with M8 nylock nuts.
9. If not already attached, bolt the winch to the top of the main frame with 4 M8 x
30 mm gr 8 hex head bolts, 8 mm washers, and M8 Nylock nuts; the bolts being
inserted from the front through the winch base
10. Remove the gr.8 U-bolt from the top of the A frame, attach the lower end of the
winch strap to it and re-attach. The strap should feed over top of the barrel of
the winch toward the front and down to the attachment point on the A frame.
(fig.13). The U-bolt should not be tightened fully. It should have a little play.
11. Align the D frame’s 3 attachment points with the two vertical centre ribs of each
plow blade panel as well as the double, joined vertical ribs in the middle of the
plow (fig.14). Insert clevis pins through each attachment point and the vertical
ribs on the back of the blade. Secure the clevis pins (23, fig.15) in place with
cotter pins and bend them so they remain in place.
12.
If not already done, attach the 2 flip-down fixed castors to the inside edge of the
last ribs on each end of the snow plow blade by bolting them to the rib. When
plowing make sure to flip castors up and insert the pin to avoid damage while
plowing.
13. If not already done, attach the swivel castor to the castor holder shaft and
slide it from below into the shaft holder in the A frame. Lock it with the castor
adjustment pin so that the frame is horizontal and the blade vertical.
14.
Hook the trip springs (18, fig.15) into the holes in the top cross rib at the back of
each plow blade panel (37/38h, fig.15). Attach the springs to the angle plates on
the D frame (5a, fig.15) using for each an M12 gr.8 eyebolt (17, fig.15), M12 nut,
2 12 mm washers and an M12 Nylock nut.
15. Tighten the Nylock nuts to the point where the springs are just tight. Then turn
the Nylock nut, shortening the take-up by 6 mm (1/4 inch) further so the springs
open slightly. Snug up the inner M12 nut to hold the assembly tight.
