Hello All:
In trying to salvage and repair a 3360 Burro Crane, I found the motor was lacking a Lionel Part # 600-129 thrust washer. My questions are if this is an essential item and also does the motor require two of these, one on the top shaft and one on the bottom shaft? Another words should I place one on each side of the commutator to take up vertical movement as the worm gear moves during operation? Has anyone ever made there own thrust washers out of standard nylon washers?
