Bottom shaft, Back-guard, Channel X-bracing:
Bottom shaft
: a 1" diameter shaft with two large sprockets. One
sprocket is fixed and the other is loose.
Back-guard:
a long flat piece with wing ends.
X-Bracing:
5/16" rod with a turnbuckle at one end.
Place the shaft
into the two bearings at the bottom of the
channels, loose sprocket to the right. Slide the bearings all the
way on - up to the stop-collars.
Tighten the bearing setscrews
, but leave the bearing bolts
loose so that the bearings can slide up and down in the slots
Make sure the setscrews are fully retracted before trying to insert the
shaft. Also, if the shaft doesn't go in easily, unbolt the bearings from
the channels and slip them onto the shaft. It's often easier and faster
in the long run.
The back-guard attaches between the channels at the back near the
bottom. It is shipped bolted together to the spacer bar. The back-
guard mounting bolts are temporary. You will replace them with
longer bolts that hold on the photocell and reflector brackets later.
Note the ends of the back-guard. The straight edge goes up. The
angled edge goes down.
Bolt the back-guard
temporarily onto the two channels with 3/8"
bolts. You will replace these bolts with the photocell bolts later.
The
x-bracing
goes between the two channels -
turnbuckles
at the
bottom.
Attach the x-bracing
to the shackles in the channels. Tighten
the turnbuckles evenly so that they are the same length and
make them finger tight. Tighten the locknuts on the turnbuckles
and fasten a piece of tie-wire through the shackle and turnbuckle
body to keep them from loosening up.
