WARNING
Improper welding procedures can damage the
structure of the mast or cause incorrect function
of the mast. Consult your Hyster lift truck dealer
for more information before welding on the mast.
2.
Clean and inspect the carriage bars for damage
and smoothness. Ensure the carriage bars are
parallel and the ends are flush. If carriage bars
have any protruding welds or damaged notches,
repair by grinding, filing, or welding.
3.
Clean the bearing areas. Inspect the sideshift
bearings for wear as follows:
a.
If either upper bearing is worn to less than
2.5 mm (0.1 in.) thickness, replace both up-
per bearings by driving the upper bearings
from the inner frame. See Figure 13.
To install new upper bearing, align the pins
on the bottom side of bearing to notches on top
carriage bar and slide into place on top car-
riage. See Figure 13.
b.
If either lower bearing is worn to less than
2.5 mm (0.1 in.) thickness, replace both lower
bearings by prying the lower bearings from
the inner frame. See Figure 13.
To install new lower bearing, align the circu-
lar pins on backside of lower bearing to holes
on lower carriage bar and tap bearing into
place on lower carriage bar using a rubber or
brass hammer. See Figure 13.
