1.1 INTRODUCTION
This operation and service manual covers the Carrier
Transicold Model 05G compressors. These compressors
are designed for refrigeration (trailer) or air conditioning
(bus & rail) applications. (See Figure 1-1) The following
table list the special tools for the 05G compressors.

1.2 GENERAL DESCRIPTION
The Model 05G compressors are of the open-drive
reciprocating type. A crankshaft, connecting rods,
pistons, and reed type valves accomplish vapor
compression. Compressor wear is minimized by splash
lubrication and by force feed lubrication. There are three
types of oil pumps (Vane, Gear and Low Profile Gear)
driven directly from the end of the compressor
crankshaft. (See Figure 1-3)
CAUTION
The gear oil pump must be set to rotate in the
same direction as the crankshaft. (Refer to
section 3.4)
The tapered end of the crankshaft, which extends
outside the crankcase, is adaptable to a variety of direct
drive or belt---driven clutch mechanisms. A mechanical
seal prevents refrigerant leakage where the rotating shaft
passes through the crankcase.
The compressor is equipped with flanges for
connecting suction and discharge service valves.
Connections are also provided for pressure gauges and
safety cutout switches. Sight glasses installed on both
sides of the crankcase, provides a means for checking oil
level in the compressor crankcase. A drain plug facilitates
draining of oil from the crankcase and an oil fill plug
enables addition of oil when necessary. A bottom plate
provides access through the bottom of the crankcase for
maintenance.
WARNING
Do not operate compressor unless suction and
discharge service valves are open.
Capacity of the Model 05G compressor is
determined by piston displacement and clearance,
suction and discharge valve size, compressor speed,
suction and discharge pressure, type of refrigerant, and
unloader valves.
