Starter Motor is this starter like a car starter with a bendix that pushies out to mesh gears? my starter spins but dose not turn engine over. I know cars pretty well, bikes are new to me. Thanks for any help you can give.1982 Suzuki GS 750 EZ

For the quad, I can only speak from automotive experience but does the starter have a smaller cylinder mounted directly on it? If so, this is the magnetic solenoid that engages a Bendix gear drive on the starter shaft into the engine flywheel gear to crank it. The actual switch that turns on the starter motor itself is in the back end of this solenoid. If the motor turns, the solenoid is working. If it doesn't have this solenoid, it will have a shallow screw drive cut directly in the motor shaft with a Bendix drive gear on it. When you hit the starter, the shaft turns quickly and basically "unscrews" the Bendix drive to the end of the motor shaft and engages it with the flywheel gear, again, cranking the engine. The weak link in both of these systems is the Bendix drive itself. It has a built in ratchet based on ball bearings so that if the shaft happens to stick in the engaged position after the engine starts, it will only spin the Bendix drive itself and not the starter motor avoiding damage to it. These ball bearings will eventually break up allowing the Bendix to free wheel in both directions instead of catching in one direction to crank the engine and slipping in the other direction to protect the motor. I hope this helps.

If the starter spins when the key is turned to start the starter relay is good . Or do you mean the starter solenoid ? then again , if the starter spins ,the solenoid is good also. Do you know how a starter works ? Could be the bendix . Do you know what a bendix is ? If the bendix isn't kicking the pinion gear into the flywheel or flex plate , the bendix is bad . Or isn't the pinion gear contacting or meshing with the flywheel . Do you know how to check these thing's ,or could need to be shimmed .

Sounds like the Bendix on the starter not working. When the starter energizes the gear on the starter meshes with the flywheel to turn over the engine. I have also heard of small rocks getting stuck in the flywheel teeth that will prevent the starter from meshing the Bendix gear with the flywheel gear.

Defective bendix on your starter simply get a rebilt starter or you just change the bendix the shaft that the bendix slide on to ingage the fly wheel could be rusty that could prevent the bendix to engage the flywheel i posted 2 video as guide there not the same years but should help you out good luck pierre

Remove the engine cover to expose the starter motor (or take the starter off). Lubricate the starter bendix, its the gear atop the starter motor shaft, use Marvel Mystery oil and then work the bendix a bit and it should fix it. If the teeth on the bendix or flywheel are damaged obviously that is where the problem lies.

If I understand your statement correctly, noise but the engine will not "turn over." This sounds like the starter motor is running but the gear that engages the flywheel gear-teeth is not making contact at all or is moving into too-slight contact, just enough to make a lot of noise. In U.S. cars the device on the stater motor that moves the starter gear forward is called a "Bendix." As the starter motor starts to turn, the Bendix shoves a small gear forward, engaging teeth on the flywheel which spins the flywheel to start the engine. If the Bendix is sticking or has failed the gear will not move forward at all or not far enough.

Sarting with the least cost first, I'd look toward a "sticky" bendix. Try using a light penetrating oil or perhaps, WD-40 to free-up the Bendix.

There are two types of starter, a bendix gear type,and a pre engaged type, neither should rotate with the engine running, with a pre engaged starter the gear is connected to the flywheel but when the engine starts a solinoid pulls the gear out of the flywheel, with a bendix type, the starter motor spins the bendix shaft which in turn winds the gear up and into the flywheel ring gear.

We dont know details about your model; the solenoid, or on some starters, just a threaded part of the armature, pushes the bendix gear forward an inch or so until it meshes with the ring gear, allowing the starter motor to spin the engine over until it starts. When the engine rpm exceeds the cranking speed, the bendix automatically retracts, preventing the engine from spinning the starter too fast.

At least that's how it works in theory. Starter motor failure is rarely caused by a blown or shorted motor itself - usually it's a problem with the bendix mechanism or the solenoid. And frankly, most people will never need to replace a starter motor for the life of their vehicle. Intrepid but underfunded Saturday Mechanics might actually dismantle a malfunctioning starter and repair it themselves. You can still find auto parts stores that can get you new bearings, brushes and bendix assemblies. Generally, I just exchange the old starter for a new or remanufactured one, because repairing one doesn't save much money. On the other hand, if you have a rare or hard-to-find starter it might be necessary to fix what you have. Usually, auto electric shops can rebuild or repair a starter with a bad armature, shorted field windings, bad brushes, a bad commutator, or even a bad solenoid if there is no alternative


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

are you sure you got a good solenoid?souds like it's not kicking the starter bendix out for the start.if it hums that means it's turning right? it has to be the solenoid not kicking the starter bendix into the flywheel to start the engine.i would try another solenoid. thank you for choosing fixya.com

CHECK THE BENDIX GEAR ON THE STARTER.. IT,SHOULD SPIN OUTWARD WHEN THE STARTER IS ENGAGED.. IT MESHES WITH THE TEETH ON THE FLYWHEEL.....GD LK, CHARLIE
