the
safety
precautions
associated with the X200-4 transmission.

INTRODUCTION
Successful repair of equipment requires that you be familiar with the
basic
principles
of
operation,
safety
precautions,
equipment
components, and with the proper use of applicable technical manuals.
In this lesson, you will learn this information as it relates to the
X200-4 transmission.
The X200-4 transmission is a part of the
vehicle drive system in the M730A2 Guided Missile Equipment Carrier
and the M113A3 Armored Personnel Carrier.
PART A - INTRODUCTION TO THE CROSS-DRIVE TRANSMISSION
Several models of cross-drive transmissions are in use, differing in
some details from each other.
However, all of them operate in a
similar manner.
The cross-drive transmission is a combination transmission and
steering unit for use on tracked vehicles.
It provides a hydraulic
drive through use of a torque converter, and contains the planetary
gearing, steering mechanism, braking mechanism, and hydraulically
operated clutches.
For purposes of this subcourse, location points
for the transmission, i.e., rear, right, left, and front, will be
determined by facing the identification plate which is mounted at the
rear of the transmission.
