WARNING
Lift chains, hoses, and cables can roll over the
sheaves to fall and cause an injury if the ends
are not fastened. Keep control of the ends of
the lift chains, hoses, and cables as they are re-
moved. Use wire to temporarily connect the
ends of the lift chains, hoses, or cable to the
masts.

Connect the hydraulic hoses from the mast to the
manifold block as marked during removal. Con-
nect the electrical cable at the base of the inner
frame.
NOTE:
The lift chains must be adjusted if the nuts of
the chain anchors at the mast were removed. Adjust
the lift chains as described in Carriage or Reach As-
sembly Adjustments.

Use new cotter pins and install the lift chains on
the chain anchors of the inner frame.
Install the thrust rollers as marked during removal.
If the thrust rollers are replaced, install the correct
size [74, 76, or 78 mm (2.88, 2.96, or 3.04 in.) OD]
thrust rollers. See Adjust Thrust Rollers, Carriage
or Reach Assembly Adjustments at the end of this
section.
