I broke the grease fitting off on a Pittsburgh Rapid Pump Heavy Duty 3 Ton floor jack from Harbor Freight. Attempting to get the rest of the fitting out, I scraped several small metal (brass?) shavings into the pivot arm. Could this cause the jack to fail when lifting a vehicle? Is it fixable? It looks like there are clips on that suggest it can be taken apart but I don't know. Any thoughts are greatly appreciated. I need to do my rear brakes but I don't know whether or not I should trust this floor jack to raise the vehicle safely.
Thanks guys.
