Regarding my garden railroad Bachmann Rail Truck, the drive line will not stay connected at either end (transmission or rear end). The transmission and rear end have a ball joint with two tips on it, the drive line has a U-joint with indentations on each end and they continually get knocked off. Any suggestions?
Get the drive shaft re attached to the u joints(ball joint w/ tips) Try putting a small zip tie around the arms of the u section of the drive shaft. Roll on the power easy, sounds like you may have a weak yoke (u joint) on the drive shaft. Hope this is some help......Later All........S.B.
