Sohaib,

I'm curious about what happened here. Similar to what Michael said above, you shouldn't ever have an issue with this. Also the bottom bolts holding the gearbox along with the geometric feature of the bearing block is holding most if not all the weight of the gearbox. The #10-32 bolts holding the bearing blocks together aren't doing much work.

Questions:

1. Do you have pictures of the plates?

2. Did you guys use loctite "gluestick" or "liquid" form?

3. Were the bolts ever loose during operation?

4. Did anyone crank down on the bolts till they stripped.

5. Was this component properly installed?

I'm curious about hearing more about this, as this specific area shouldn't ever fail. Again please email me directly at rc@wcproducts.net. I'll try to get back to you when possible.
