0 Adkat Posted July 8 Share Posted July 8 G'day Chaise, firstly welcome to BMT! Some pics would help give an idea of what you're dealing with. In regards to the cracks and sheared bolt, did they happen consecutively, or were repairs done to fix the issues as the came along? Where abouts did they crack? Which mount bolt let go? What's the condition of the mounts? Are there bolts missing from the gearbox to flywheel housing? Does it have the steel bar mount on the back of the box? Hopefully a bit more info can help get you sorted Quote Link to comment https://www.bigmacktrucks.com/topic/74329-mack-e7-bellhousing/#findComment-554920 Share on other sites More sharing options...
