Terex ASV SR70, Service & Repair Manual

Note: The metal face seals are a 4-piece design with
one rubber outer seal and one metal face seal fitted
into each wheel and one rubber outer seal and one
metal face seal fitted into each hub. As they are
assembled, the metal halves mate and ride against
each other on a thin layer of oil to seal out dirt and
debris. Figure 13-18 shows the various components
that make up a face seal. Figure 13-19 shows the seal
as a mated assembly.
6. Once the wheels have been removed, use a press
to push the axle and far side bearing out of the
hub as shown. (fig. 13-20, 13-21)
7. If it is necessary to remove the other bearing for
replacement, press it out as well. If not, you may
leave this bearing in the hub during cleaning.
8. Clean all parts (including wheels) thoroughly with
parts cleaning solution and dry them prior to
reassembly. Wipe the inner hub surfaces to
remove any solvent or oil residue. (fig. 13-22)
9. Reinstall the bearing and shaft into the hub as
found upon disassembly, then press the bearing
back into the hub over the shaft. (fig. 13-23)
