Compressor and Magnetic Clutch Assemblies

6P148 Compressor

NOTE: Whenever a compressor is replaced, the suction accumulator/drier and orifice tube must also be replaced.

The 6P148 compressor is a swashplate design, six-cylinder radial mount compressor driven by a belt from the engine crankshaft.

The 6P148 compressor has a displacement of 148cc (9.0 cubic inches). Lubrication is provided by a charge of refrigerant oil that is added to the refrigerant system and circulates with the refrigerant. The specified refrigerant oil is Motorcraft YN-9 or an equivalent oil containing the same special additives as YN-9 oil. Refer to Section 12-03C for adding oil.

The compressor shaft is driven by a belt from the engine accessory drive. Three double acting pistons, positioned axially around the compressor shaft are actuated by a swashplate that is pressed on the compressor shaft. The swashplate uses the rotating action of the shaft to provide a reciprocating driving force to each of the three pistons. This driving force is applied, through balls and shoes, to the mid-point of each of the three double ended pistons.

The suction and discharge manifolds are attached to the top of the compressor with two screws, and the pressure relief valve is threaded into the discharge manifold. The 6P148 uses forged aluminum manifolds.

The clutch consists of three basic components: the pulley, hub and the field coil. The pulley and field coil are attached to the front head of the compressor with tapered snap rings. The hub is keyed to the compressor shaft and is retained with a nut and lockwasher.

Refer to Section 12-03C for 6P148 compressor and clutch service procedures.

10P15C Compressor

NOTE: Whenever a compressor is replaced, it will be necessary to replace the suction accumulator/drier.

The 10P15C compressor is a 10 cylinder axial design compressor with mounting brackets for tangential mounting. The compressor shaft is driven by a belt from the engine accessory drive. Five double acting pistons, positioned axially around the compressor shaft, are actuated by a swashplate that is pressed on the compressor shaft. The swashplate uses the rotating action of the shaft to provide a reciprocating driving force to each of the five pistons. This driving force is applied, through balls and shoes, to the mid-point of each of the five double ended pistons.

The suction and discharge manifolds are attached to the top of the compressor with two screws, and the pressure relief valve is threaded into the discharge manifold.

The clutch used consists of three basic components: the pulley, hub and the field coil. The pulley and field coil are attached to the front head of the compressor with tapered snap rings. The hub is keyed to the compressor shaft and is retained with a nut and lockwasher.
