KitchenAid Pro 600 - Screw threading

Have a problem with gears jamming. Replaced Bevel and housing gear.
When replacing screws all are snug except the front left in housing when facing the machine. when I pulled out the screw there was metal filings.
What can I do? Am I going to have to replace the whole bottom section motor an boards to have it repaired…

Looking for options… Thanks for any help…

I’ve experienced a similar problem and I’m planning to take mine back to Walmart since it’s still under warranty, just fixing my atv plows this week.
