Starter problem revisited

Stephen Newell · Nov 1, 2021

I took both the Delco starter and the Prestolite starter to an starter shop and had them overhauled. When I got them back the Delco starter would run but would only turn the engine 1 revolution and stop. I took it off and put the prestolite starter on and the tractor started quickly and easily. Don't know what the issue is, I took the starter back to the starter shop this morning and they can't find anything wrong with it. Still they said they would tear it down and inspect it better.

I've had that happen, pay to have a starter fixed and it still had no power.

Hard to bench test a starter. It might run, but doesn't mean it passes a load test.

Since I slept since yesterday and several times since October 17 when you last posted about the starter on your Case 210B I will add a link to your previous post. I see some talk about a questionable solenoid in the other post. Does each starter have its own solenoid? If so it could be possible the solenoid contacts on the Delco are not conducting properly under load but will test okay for just the spin test in the starter shop. Just a thought. Starter mount area on tractor and starter nose contact area are free of paint on the Delco so that was sure to be making a good ground connection?
Edit to add: Probably preaching to the choir but loss through solenoid contacts during start cycle could have been checked with a volt meter while on the tractor.

I sent a starter to an electro shop for overhaul. New bearings etc. and a new solenoid. When it came back it would not crank at all and it heated up instantly. He claimed he had it tested and it must be my battery or something else that was bad. Had a long discussion and he agreed to send me another rebuilt starter if I returned the first one. Same result with that one. No cranking and hot as hell in no time. So I got an experienced mechanic to look at it and there was no doubt, the starter was defective. Now I really needed to use the tractor so I lost my patience and bought a new starter. Put it on and tractor started willingly. So I claimed my money back from the shop and he was furious because I had went on and bought a new one instead of giving him a third chance. I met with him later on and he handed me the money back and admitted that the new solenoids he put on were the culprits. It turned out his whole stock of them was bad.

No, it has a separate solenoid similar to this one.

I think you understand but let me clarify this way. After the Delco starter failed to start it you removed the starter from the tractor. Did you then have to take the solenoid off the Delco starter and install it on the Prestolite? If so that would prove my possible theory wrong because the solenoid carried enough amps to start the tractor. If each one has a solenoid that stayed bolted to the individual starters then I was saying it is a possibility that the solenoid with the Delco starter may be at fault.

Stephen Newell · Nov 2, 2021

Neither of the starters have their own solenoid. The solenoid is bolted to the tractor instead of the starter. The same solenoid was used with both starters.

Now you have me wondering if the solenoid is burned a little and would carry the Prestolite but not the Delco. I may pick up another solenoid when I get the Delco back and change it if the tractor still fails to turn over with the Delco starter.

Where I used to work there was a tool that hooked up to the drive & locked the starter. Then you could check the volts & amp draw & also the torque.

Being that one starter was happy and the other though trying was not completing a revolution may indicate either the need for some shimming or possibly there is a burr, dirt, rust... on the mounting surface of the starter or engine.

Minor variance in machining from one manufacturer to another or even variance between two starters from the same manufacturer could explain why one works and the other does not if there is wear or a problem on the engine it is being attached to.

A flywheel with a few less than perfect teeth on the ring gear can create a high spot.

A bent or incorrect mounting stud or bolt.

A loose or cracked bellhousing

"Inspect it BETTER"??? Makes me wonder if he did anything at all the first time.

The starter wouldn't run on the bench at all before they worked on it.
