[quote]QUOTE: Originally posted by gsetter Ken you say lubing the drive couplers helped. Just as an experiment, if possible, flip the drive shaft the other way around. I'm wondering if it has a wear spot. Is the motor and transmission tight and aligned? This is where those [url="http://www.ares-server.com/Ares/Ares.asp?MerchantID=RET01229&Action=Catalog&Type=Product&ID=82896"]rollers[/url] would be handy. But $60! [:O] Ouch! [/quote] Oops. I hit enter too quick and posted a blank reply. Sorry! I FOUND THE PROBLEM BUT NOW I HAVE ANOTHER! The brass bushings that hold the worm gear/shaft in place (inside the gearbox) are not machined closely enough, and therefore have a bit of "slop" between the bushing and the shaft.. This allows the shaft to move around a bit and to chatter (or "sing") when in motion. My "Fix" is to slobber Lubriplate all over the bushings. No More Noise! BUT...... now the rubber "tire" on driver #3 of the rear engine keeps falling off. I can't tell if it's stretched out of shape, but the engine won't move 10 feet before it comes off again. Can I glue it in place? Or must it be replaced; and, if so, where can I get them?
