Noritsu 3800 BF bellows leaking/crack in bellows

[Album King]

I have a crack in the BF bellows that the pump isn't working anymore. I can see the crack in the bellows, so I think it is just the bellows and not the motor as well. I cannot figure out how to take it out for replacement. Does anyone have a diagram or explain how the bellows comes out from the housing?

Hi. If the bellows is not moving at all and there are no sounds coming from pump's motor - most likely the motor is dead also.

The housing that holds three pumps has screws - look for them, unscrew and release the housing. Then you'll be able to release  and get the pump - it is fixed to the housing on the bottom. This is a simple procedure and if you'll still be getting problems with pump's maintenance - i'd suggest you'd better find a service engineer.
