I am looking for the small nylon gear in the hand car drive mechanism. Not the gears that are driven by the screw drives but the other small nylon gear on the wheel axle.
You might check with NWSL. The original guy just recently retired and was initially having problems finding a buyer so had lots of inventory on sale. I stocked up on several things. But then an employee bought it and I read somewhere that they have little G stuff listed, but worth a check.
thanks for your suggestion _ Ill email him to see.
