I am trying to decide if I should lubricate the large and small gears. They are working in a dusty environment so I am trying to think what the dry solution would be. I bought the graphite spray to coat cast iron exhaust manifolds actually which it does an excellent job of. I have not actually use it for lubrication but it seems like a good application. Did you all lubricate these parts?

Has anyone repaired the rubber mounting blocks I'm showing here? I was hoping they'd be available as spares but they're included with the motor and mine are deteriorating.
