So a customer has a screw conveyor (5 actually but this is the only issue) that somehow had a shear bolt installed between the gear box and the frame. It looks like an adapter sleeve was made as someone made the shaft a foot too short.
What seems to be there, is the OEM drilled and tapped a socket head bolt to lock the main shaft to the sleeve. Naturally the head broke and it is not a through bolt.
The issue is that it has to be drilled in place. There is a huge list of issues with the OEM doing stupid things so that is why it must be drilled in place.
I'll get pictures soon, but I need to drill a 5/8" hole through a sleeve and shaft that totals 2 7/8" total. There is a 4" gap total between the GB mounting plate and conveyor hopper frame, but the hole is off-set so thick 2.5" x 1.5" so a drill dead center isnt an option.
At the closest point, the drill have to be 11.5" to drill through everything including being 3/4" installed in the drill.
There is a leg welded in place which restricts the idea of welding a steel plate and using a mag drill. I could use a mag drill, but the drill bit would have to be about 22" long total.
Does anyone know where to purchase drill bit extensions that can handle a 5/8" drill bit and the torque at 20" away?
Does anyone have a better idea?
