TU-FLO

501 AIR COMPRESSOR

SD-01-337*

DESCRIPTION AND OPERATION

General

The function of the air compressor is to provide and maintain

air under pressure to operate devices in the air brake and/

or auxiliary air systems.

Description

The Tu-Flo 501 is a two cylinder, single stage, reciprocating

compressor with a rated displacement of 12 cubic feet of

air per minute at 1250 R.P.M.

The Tu-Flo 501 is constructed from two major assemblies,

the head and the crankcase. The head houses the discharge

valving and is installed on the upper portion of the crankcase.

The crankcase is a one piece casting combining the cylinder

block and the crankcase. The upper portion of the casting

houses the cylinder bores and inlet valving; and the lower

portion, the crankshaft and main bearings. Various mounting

and drive configurations, required by the numerous vehicle

engine designs, are obtained by bolting different mounting

flanges, end covers, and base adapters to the crankcase.

Two horizontal governor mounting pads are located on either

side of the upper portion of the crankcase to provide

convenient governor mounting.

Two methods are employed for cooling the Tu-Flo 501 during

operation. The cylinder head is connected to the engine’s

cooling system, while the cylinder bore portion of the

crankcase has external fins for efficient air cooling.
