The safe and reliable operation of all motor vehicles depends on proper service and repair procedures. The procedures recommended and described in this manual are effective methods for performing service operations.This manual contains information which should be followed to minimize the risk of personal injury to service personnel or damage to vehicles through unsafe service procedures.This information does not cover all the possible service hazards. Accordingly, anyone using a service procedure or tool not recommended must first be satisfied that their safety or the vehicle's safety will not be jeopardized by the method selected.
General Description
The EL-1300 and EL-1600 Air Compressors are water-cooled, two cylinder, reciprocating piston-type air compressors that are designed for high performance with maximum durability for extended life. They can be base or flange mounted. The air compressor is an air pump that fills an air supply tank with compressed air. The crankshaft in the air compressor is driven by the engine and the air compressor operates when the engine is running.Air Compressor Operation
The EL-1300 and EL-1600 Air Compressors are identical except for the crankshaft stroke, the rated displacement, and the height.EL-1300 Air Compressor* The stroke is 38.1 mm (1.50 in).* The rated displacement (at 1250 rpm) is 12.9 cubic feet per minute.EL-1600 Air Compressor* The stroke is 47.5 mm (1.87 in).* The rated displacement (at 1250 rpm) is 16.1 cubic feet per minute.* The height of the EL-1600 Air Compressor is greater by 4.8 mm (.19 in) when compared to the height of the EL-1300 Air Compressor.

(6) Air inlet (from inlet air manifold of the engine). (7) Cylinder block.(8) Passage (to the top of each unloader valve in the cylinder head).(9) Crankcase.Coolant from the engine enters coolant inlet (5). Coolant inlet (5) on some air compressor installations is in cylinder head (4). The coolant from the air compressor flows through coolant outlet (1) and to the engine cooling system. The engine water pump moves the coolant through the air compressor when the engine is running.

Cylinder Head, Air Outlet Section (13) Outlet valve.(14) Outlet valve stop.(15) Spring.The lubricating oil pump for the engine forces compressed oil through a passage in the air compressor crankshaft to each of the connecting rod journals of the crankshaft. The lubricating oil flows from the air compressor crankcase through holes and into the timing gear housing of the engine.There are two inlet valves (10),
