    I have an MB BF 70.2 crusher bucket and would like to start a discussion about them (or at least crusher buckets). I am using it for crushing on-site shot rock, or hammered rock, into a use-able product (structural fill, road base, or backfill). I have been having some issues with it and I can't seem to find any source of information or support. The support from MB is almost non-existant. I can call and get parts but there is no fruit when it comes to getting any answers as to why I'm having the issues that I am. I would absolutely love to have a disussion with other owners/users of this, or similar products, to share insights and knowledge. Please chime in/introduce yourself if you think you have something to contribute to this topic. I am more than willing to share what information I have gathered in return.
    I have had mine for about a year and have crushed limestone, sandstone, gneiss rock, granite and concrete. I have replaced several toggles (always break at the weld of the narrower end (at the jaw support), have already been through a set of dies (seem to have worn out very quickly), have replaced the bushing at the end of the preload shaft (recommendation of MB to address the toggles breaking), and I am now seeing cracks on the jaw support (at the corners of the rectangular pocket that holds the toggle). Any advice would be appreciated.
