You could also try the local buy and sell, maybe you can find a machine for what you'd rent one for. It's a new market to you, if it's far enough from home. Then take it home with you when your son's better, or leave it there. Either way, maybe pick up some oil. It's not a high tension part, if you find something that will fit the hole, maybe just put a small piece of duct tape under the hole so it doesn't fall through.
