As of now I get no connection between the starter motor and the crank/flywheel. Haven't gone back to the shop manual yet. Anyway, when I hit the starter switch all I get is the sound of the starter motor whirring. Last week I was having a little problem with it, so in the evening I started it twice in my garage. No problems, let it run a few minutes each time. Next morning it was what it is. No go. I leave it connected to battery tender when it's at home. Thought & ideas? | ||

Could be just a bad starter. | ||

Update. This evening got a burr up my butt and tried something. Turned the ignition switch on and held the starter switch down. After a little over a minute the clutch started to grab. Maybe 30 seconds after that it really caught and started the motor. By then I had a "Low Battery" alarm. Am thinking a new battery is in order, at the least. More tests tomorrow. | ||

There is an over running clutch on the alternator side of the engine. To access it, remove the stator and cover. Loosen the magnet nut and remove from crank. Normally the Sprague assembly will come off with the rotating magnet. You will see what looks like two gears mounted on the female spline. The outer is the timing clock wheel, it will have the missing tooth, and directly behind this will be the Sprague and starter gear. This gear is supposed to rotate in only one direction. The Sprague looks like a simple roller bearing, but the rollers are egg shape. In operation they lay over on their side in one direction and slip. When rotated in the opposite direction, the rollers stand up on edge and jam the outer and inner races locking the unit. You will easily see the fault once it is in front of you. Do not let the starter motor freewheel, as it will easily overspeed and potentially throw the armature windings. These motors are series wound and have no reluctance speed regulation! To remove the Sprague from the magnet, there will be six cap screws. Just remove them and fiddle it apart. |
