Mamiya 645 lens aperture cleaning?

Hi, I got an at first sight excellent specimen of the Mamiya 55mm 645 lens from ebay.

Alas, the aperture sticks to wide open. It seems to happen sometimes with older mamiya lenses that the oil makes the aperture blades stick and they must then be cleaned

is it difficult to open the lens to clean the blades? I can get a discount if I keep the lens to fix it or I can return it.
