Starter Problems

I have a 2016 570 EFI that isn't starting correctly. Over time it has gotten where it wouldn't engage and start. Sometimes it would start and other times it wouldn't. I have taken the starter off and the gears look OK. I have watched You Tube on how to change this so I then went inside and checked the gears on the inside and they all look good. No signs of gear damage or shavings. I have also replaced the battery. I'm thinking the starter is not staying locked in while starting the engine. Can anyone give me experienced info on this matter.

Thanks for the information this helps. The starter will spin but will not stay engaged. Sounds like the old starter bendix of past not staying engaged and having striped gears. I had about decided it was the starter or starter solenoid. Question where do most of you buy your parts?
Ok here is the latest. Replaced starter, solenoid, one way bearing. Checked other bearings and gears as directed by manual. All back together but when I try starting it the only thing I get is starter engages and runs but nothing else happens. Gear behind flywheel only moves in a clockwise direction. Any help on what I may have done wrong or need to address?
Based on your description, it seems that the issue with your 2016 570 EFI could be related to the starter motor or the starter clutch mechanism. The starter motor is responsible for turning the engine over when you turn the ignition key, while the starter clutch is a one-way clutch that engages the engine when the starter motor turns.

If the starter motor isn't staying engaged with the engine, it could be a sign that the starter clutch is slipping, preventing the motor from turning the engine over. This can happen due to wear and tear on the clutch or due to a lack of lubrication, which can cause the clutch to wear out more quickly.

One thing you could try is to inspect the starter clutch and the related components, such as the starter gears, for any signs of wear or damage. If you notice any issues, it's best to replace the damaged parts with new ones. Additionally, you may want to lubricate the starter clutch mechanism to ensure it works smoothly and efficiently.
I have replaced the starter and the one way bearing with new ones. The starter is turning, clockwise when we turn it over making the gears between the starter and flywheel gear turn counterclockwise and the flywheel gear to turn clockwise or to the right as it is stated to do. The problem is the engine will not turn over. Does the engine have to be in a non compression phase to turn over the first time?
I am old school and don't understand this one way bearing set up to start an engine. Someone please explain.
The manual I have says that the one way gear should only turn clockwise on the bearing, which mine does. It will not turn counterclockwise. I have had the engine open twice. Have checked and replaced the starter, one way bearing and starter relay. Everything seems to work as expected by my repair manual. Someone suggested that I might have put the one way bearing on backwards since all it will do is spin the starter and I'm guessing its turning the gear on the one way bearing.(Clockwise) If I reverse the mounting on the bearing I'm guessing that will lock up the bearing and cause the engine to spin clockwise. I'm guessing that is which way the engine runs. What I don't understand is what happens to the one way bearing?
It is like a bicycle.

The starter spins and the gears turn. The one way bearing on the final gear grabs the flywheel and starts to spin it. Once it gets turned over a few times, the engine fires and starts spinning faster. The flywheel attached to the crank starts spinning faster than the gear being spun by the starter, this frees the one way bearing as it's being overdriven so it is free to spin now.

So back to the bicycle analogy, you pedal the bike. You get to a hill and gravity makes the bike go faster than you can pedal. You stop pedaling and coast letting gravity take over.

ETA: to check the one way bearing interface is good, it should spin freely one direction (the gear should spin independently around the flywheel) and it should bind (grabing and locking with the flywheel) the other direction.
Is it a clockwise rotation or counterclockwise?
