Description
The Rockwell T-2111-D, T-2111-PD, T-2111-T,
T-2111-HP and T-2111-SD/SPD/ST transfer cases
are a three-shaft design with single speed front and
rear output and 1:1 ratio for use with 4x4 and 6x6
vehicles. Their 16.125 inch (409.5 mm) input to
output drop permits engine clearance. Figure 1.
NOTE:
The T-2111-SD/ST/SPD transfer cases vary only in
their main case configuration from the T-2111. All
options and features are the same as described in
this Maintenance Manual.

from the cab. By activating an air plunger or electric

each of these devices. Optional indicator switches
show when each clutch is fully engaged or
disengaged.
