• SCHP-100x and 500x can use the KSM-440BAM drive but you need to replace the top cover of the BAM with the one from the original drive mechanism (KSM-440AAM or KSM-440ACM)

• KHS-400A can replace the KHS-400B only if a thin metal plate is taped to the side of the housing to form a metal corner like the B one, but it can’t replace either KHS-400C or R because of its thick base.
• KHS-400B can repace KHS-400A without any modification but this model is not suitable to replace the C and R models due to its thicker base.
• KHS-400C is thin and therefore can replace the A and B model as well as the R model.
• KHS-400R is also thin and can be used in place of the C model as well as the A and B models. This model has a direct replacement from Sanyo bearing the model SF-HD7.
