3. Turret Assembly Installation. Theturret assembly mounts on the RH side onto the center section
under frame (See Figure 36 & 37) . Using a hoist (or other lifting device) lower the turret assembly until
it is level with the underframe. Slide the turret assembly inward toward the under frame until the retaining
pin tube on under frame an turret assembly align. Installthe long upper retaining pin and then the two small
front and rear pins. The long upper pin is retained with two cotter pins that need to be bent over on the
ends. The short pins are retained with nuts and bolts (See Figure 36 & 38).

4. Turret Assembly Grease Fittings. The turret assembly has three grease fittings around the OD of
it. The grease fittings are 120° apart, this is to make certain that the bearing will be greased all the way
around because of the large diameter of the bearing. This bearing must be greased before unit is put into
service. It is easier to get to grease fittings now than after boom has been installed. On the under side
of the turret assembly are the grease fittings for the swing cylinder pivot mounts, these need to be
greased before operating the unit. Also there is a bolt on cover on the under side of turret that will be
installed (See Figure 40) at a later time. Greasing the cylinder pivots will need to be done before the cover
is installed (See Figure 39) and the boom swing stop will need to be adjusted, but this cannot be done
until a later time making it best to leave this cover of until then. After greasing components at assembly
of unit operator should consult the operators manual for maintenance requirements.
