Tension Arm Installation
2)
Remove the long bolt (with its nut and washers) from the pulley
end of the tension arm.
3)
Put one of the washers back on the bolt and push the bolt through
the upper hole in the left rear vertical from the outside.
4)
Put another washer on and slip the tension arm (with its metal
bushing) onto the bolt.
5)
Add another washer, then the hex nut, and tighten it down.
6)
After tightening, check to make sure the arm swings freely.
Attach the Tie-up (Cord or Cable)
1)
Find the tension arm cable (#38S) for the one yard sectional beam
or the tension arm cord (#38P) for the ½ yard sectional or plain
beam.
2)
Attach the cable or cord to the tension arm by removing the
shoulder bolt (the bolt near the wooden pulley) using a 5/32" Allen
wrench and place this bolt through the looped end of the cable or
cord and replace the bolt into the tension arm.
3)
The cable comes from the bolt in the tension arm, over the top of
the tension arm pulley, and down around the front of the sectional
beam brake drum.
