11. Place the contact support assy. into the outside
beam & tighten the fasteners (3). (Fig. 2)
12. Install the woodruff key, contact sheave, flat
washer, and new lock nut.
13. Tighten the lock nut by holding the sheave with a
strap wrench, then verify freedom of rotation.
14. Place the take-up shaft assy. into the bushing of the
inside beam & rotate counter-clockwise. (Fig. 3)
15. Place the tension slide assy. t-slot onto the track
stud and position the slide dowel pins into the slots
on the inside beam. (It may be necessary to lift the
tension shaft over the take-up shaft assy. bearing)
16. Place the tension bushing onto the tension shaft.
17. Rotate the track knob until the tension slide is
parallel with the inside beam, taking care to engage
the tension bushing correctly with the beam.
18. Position the drive belt onto the motor sheave so
that the belt remains inside of the beam cavity.
19. While maintaining tension on the drive belt, install
the outside beam assy. making sure that the contact
sheave is fully engaged and centered with the belt.
This is best achieved by “hanging” the outside
beam over the idler support, then pulling the far
end of the belt out of the inside beam (slightly) in
order to position it over the contact sheave.
20. Maintaining tension on the belt, slide the inside
beam so that the dowel pins engage and the beams
come together. The tension slide and take-up shaft
will also align with the outside beam at this time.
