INSPECT
1.
Inspect the rollers for excessive wear or dam-
age. Rollers with visible flat spots or cracks
should be replaced.
2.
Inspect the load roller bearings and thrust
roller bearing by turning the rollers on their
shafts. Rollers with roughness or noticeable re-
strictions to turning must be replaced.
WARNING
Welding repairs to the reach carriage assembly or
mast must be factory approved by Hyster
®
before
the repair is performed. Written instructions out-
lining specifications and welding techniques will
be provided upon approval to ensure the struc-
tural integrity and safety of the repair.
3.
Inspect all welds between the reach carriage as-
sembly side plates and the carriage fork bars. If
any welds are cracked, repair or replace the
damaged components as necessary.
4.
Inspect the roller stub shafts. If they are dam-
aged or if there are cracks at the base of the
stub shafts, repair or replace the damaged com-
ponents as necessary.
5.
Inspect the chain anchor mounts for wear or
damage.
6.
Inspect the lift chains for wear or damage. If re-
moved, clean and lubricate. See Lift Chains.

Position the reach carriage assembly in an up-
right position in front of the mast. Align the
load rollers on the rear frame of the reach car-
riage assembly with the inner mast.
WARNING
Mast assemblies are heavy. Be sure that all lifting
devices are suitable and of adequate capacity to
lift the components.
NOTE:
Use an overhead lifting device of suitable
capacity to raise the inner mast when installing the
reach carriage assembly. Use second lift truck to
position the reach carriage assembly if the first
truck is not mobile.
2.
Raise the inner mast until clearly higher than
the reach carriage assembly. Position the reach
carriage assembly so the load rollers on the
rear frame are centered within the channels of
the inner mast.
