How do you replace air brake compressor on an international 7400?
Disconnect the oil and air lines to the compressor, disconnect
the fuel pump (if yours is attached to the compressor), remove the
bolts holding it in place, clean all mating surfaces of any
remaining gasket material, transfer any fittings from the old
compressor to the new one, and reinstall it.You want anything more
specific, we need to know which engine and which model years, as
some models with the MaxxForce engine used a non-unloading
compressor which was driven by the flywheel.
