Section 7. Component Procedures
Mast Disassembly and Shimming
4. Use spare shim(s) as a gauge to determine
the amount required to move the roller
bearings outward to make contact with the
main frame.
5. Remove the outer mast from the main
frame.
6. Remove the roller bearings from both roller
bearing bosses at the bottom of the outer
mast.
7. Install half of the total shim thickness
required to each roller bearing boss at the
bottom of the outer mast. (Applying one
half of the total shim thickness to each
side of the mast maintains the center line
of the mast assembly.)
8. Reinstall the roller bearings. Torque the
bolts per Table 7-2.
9. Use a suitable lifting device and reinstall
the outer mast into the main frame. Check

OTE
main frame will result in the wrong
amount of shims, since the studs are
canted.
12. With the outer mast fully nested, use a pry
bar and carefully move the outer mast to
the opposite side. Using spare shims
between the bearing and outer mast,
determine the amount of shims required
to remove side play.
13. Remove the roller bearing assemblies.
14. Install half of the total shim thickness to
each roller bearing assembly.
15. Install the roller bearing assemblies and
attach with the mounting bolts and
tighten.
