MultiStar Cold – Your Source for Bus Air Conditioner Parts
The Bock 80154 crankshaft is the main rotating power component for Bock FK40 series reciprocating compressors widely used in bus and coach air conditioning systems. Precision forged and machined to OEM dimensions, this crankshaft converts rotary motion into piston reciprocation. It is the ideal replacement part when the original crankshaft suffers from wear, bending, journal damage or fatigue failure during heavy-duty mobile operation.
