Description
Meritor MTC-4208X/XL/XP/XLEV/XLEC, MTC-4210X/XL/XP/XLEV/
XLEC and MTC-4213X Series transfer cases are four-shaft designs
with two-speed front and rear output having a 1:1 and a 1:2.05
ratio for use with part-time 4x4 and 6x6 vehicles. The MTC-4208
and MTC-4210 Series are designed specifically for use in 4x4
vehicles (the MTC-4213 Series is designed specifically for 6x6) as
part of the Meritor medium-duty 4x4 drive system. Figure 3.2.
TYPICAL 4X4 HOOKUP
Figure 3.2
The air-actuated front-axle declutch (if equipped), high and low
shifter and full-torque power take-off (PTO) lockup are controlled
from the cab. An air plunger or electric switch, usually mounted on
the instrument panel, engages or disengages a mechanical clutch.
An optional speed sensor measures transfer case output driveline
rpm. Optional switches indicate when the front axle declutch is fully
engaged or disengaged.
These transfer cases provide for two-speed output (high range and
low range) and a neutral position used for PTO-equipped transfer
cases only. Non-PTO cases can have this neutral position plugged
with a breather. Figure 3.3.

The front axle declutch permits shifting from part-time 4x4 or 6x6
operation to rear-wheel drive (RWD). Figure 3.4, Figure 3.5 and
Figure 3.6. Engagement can be confirmed by hearing it, noticing
improved vehicle performance, or observing the optional indicator
light in the cab.
The full-torque PTO option provides an outlet to drive auxiliary
power devices. Figure 3.7.
Optional switches for full-torque PTOs indicate full engagement or
disengagement.
