Time for a new starter on my 724cc B&S?

Briggs and Stratton 724cc, 22HP driving a Craftsman 917-203911 (aka T3200)
Model: 44R677, Type 0019G1

Pinion gear will not engage the flywheel. The starter itself spins very quickly, but the gear doesn't move up properly.

It did this a few months ago - I started by checking battery and solenoid (both fine) before getting to the starter. I took off the starter and it seemed a little gummed up, so I took a soft wire brush to the top and that seemed to do the trick - worked fine for last few months. But this morning it was doing the same thing again. Starter was a little dirty up top, but no where near as bad as before (few months' worth of dirt and oil vs 5+ years of buildup). But the pinion gear was not spinning very freely again, so I cleaned it again, reinstalled it and then it started fine. Is this the time to replace to the starter, something else, or do I need to do something different to oil, or grease or lubricate it? I did try hooking up the battery booster for a good 15 min before I pulled the starter off - just to make sure it wasn't a case of the battery not spinning it up fast enough or something.

I think I'm all original parts still, except I'm on my 3rd battery. I'm handy enough to do the replacement myself, but not that familiar with small engine work.

Looks like the cheapest I can find the starter is actually from B&S website https://www.briggsstrattonstore.com/briggs-stratton-part-592599/. I am a little concerned that all the starters I was finding at Amazon were either 14 or 16 tooth and mine is 15. Is that the reason mine is $150 and all the others are $50?

Would it work to swap my 15-tooth gear onto a cheaper starter? Maybe onto something like this? https://www.amazon.com/Owigift-Starter-Replacement-592599-Stratton/dp/B097YSMC2N Or is more a matter of getting what you pay for so I should stick with OEM?

Thanks for help!

No it is time to replace the pinion and perhaps the entire bendix Stens starter rebuild kit
However something does not add up here
The starter according to your engine number is a 16 tooth model
So have you owned this mower from new ?

Hmmm, The image of the 592599 starter (which the IPL lists as the correct starter) indicates it don't use that Bendix.

That Bendix is for the 590476 starter.

Now they might have use the 590476 but didn't show it in the IPL. It won't be the first time for Briggs screw an IPL.

And this 590476 starter Bendix does wear out over time and start to slip just like the Kohler starters.

Now Stens does have a starter Bendix (438-859) that fits the 592599 starter but the OP would need to reuse his old steel gear as the Stens kit comes with a plastic gear.

I bought it new (back when Sears was going out of business and closing most of their local stores). The mower is all original parts (except battery and filters/plugs). My starter does look exactly like the 592599. I can't count the teeth on it to make sure (mine is the 15 tooth model) its a metal gear.

I found my engine parts manual on B&S website, so I'm pretty sure the 592599 is correct. https://www.briggsandstratton.com/n...wnloadmanual.44R6770019G1~_IPLURL_LO.pdf.html

I see B&S does sell just a starter clutch https://shop.briggsandstratton.com/...ducts/briggs-and-stratton-692024-drive-clutch, but I don't see a kit with the spring and end cap.

I appreciate the help!

The metal gear on the 592599 is a 14 tooth version.

This is what is creating the confusion.
All of the aftermarket parts suppliers do replacement drives and some just the gear which is what usually wears .
So Rotary, Prime line , Oregon & Stens all have rebuild kits.
The parts in the kit are the parts that need replacing
If it is not in the kits it is because it does not need replacing .

It not confusing when you know which gear matches the flywheel. Briggs as far as I know only has three different gears for the starters. Two fit the same starter motors (depends if the flywheel ring is steel or not) and the third only fit one style of motor.

Besides replacing the retainer clip is a pain without the proper tool but is quite easy when you got the tool. I had a customer to fool around for two hours trying the get that ring on. Then he brought in the starter and took longer for me to get the tool out and back than the actual installation of the ring.

Stens 435-859 Starter Drive Kit on order - will try that, but keeping my 15-pin pinion gear. (I have a steel flywheel, and I don't see anyone selling the 15-tooth gear. So I'll just re-use mine.) I'll update the thread when I have the repair complete.

Installed the Stens 435-859 kit - swapped out both the pinion gear and the metal cup that goes on top from my original starter. (The hole in the cap from the 435-859 kit was too small, and I have the 15-tooth gear). I hadn't noticed it before, but my 15-tooth pinion gear is actually metal teeth, but its plastic/composite on the inside (that wasn't obvious until I disassembled my starter and really scrubbed it down.)

Starter seems perfectly fine again - thanks all for the help.
