September 2010 Randy's Electrical Corner

Most motors I've had apart have a ball bearing that the nose or snout rides on. The busted one didn't, but it looked to have a powdered mess where a bearing might have been. So, I took the bearing from the donor and dropped it in. Problem was, the bearing was bigger than needed, and the concave surface of the snout wouldn't accept it, making the whole armature ride 1/4-inch too far out of the case. I used a drill bit of approximately the right size to cut the 1/4-inch out of the snout and get the armature to ride where it needed to be. I then greased the gears that drive the Bendix and the bushing in the back of the case. It isn't a permanent fix, but the Jeep has a couple thousand miles on it and a couple of hundred starts since the repair and it's still going. View Related Article
