Briggs & Stratton starter/ring gear difference

Little info showing different starter gears and ring gears used on Briggs & Stratton engines.
Always a good idea to check your gear lash when installing a new starter gear to avoid flywheel ring gear damage.

[@spikey12121]

Would like to add, the ring gear IS NOT part of the casting as stated in the video. Its like almost any real engines flywheel ring gear, it needs to be heated and sweat on. Gears that fine are almost never cast. Large teeth maybe but thats a machined ring and pressed/sweat on the cast flywheel

OOPS😅 I appreciate the comment they help a lot😉👍 Still little new to KZbin just starting to learn how to edit videos.👋

[@MowersNBlowers]

Good info man...one of the only ones that talk about this.

[@PullerbearEd]

Great tip. I knew there was a difference but never knew exactly what it was.

[@willyck948]

i learned hard way theres different size ring gears replacing vanguard engine and flywheel forgot to swap the starter🙈

[@osengasimplicity]

Good tip and love to know these points when working on them

[@johnveroutsos]

Great video, thanks man!!! I have a 1975 Toro 8-32 snowblower (Briggs and Stratton) with cast-iron (or steel, not sure) flywheel and it's an absolute beast to pull over by hand. I finally got my hands on a 120V plug-in starter but has the nylon gear on it. You're right, the gears do not mesh. I will order me a metal gear and try that. Thanks again!!

Very useful info. Thank you for taking the time to make this video and provide the information.

[@willyck948]

Your welcome

[@Michaelc-gn3eg]

Agreed with you on this one. I got a riding lawnmower that had a nylon gear on the fly wheel part of it the ring gear I replaced well tried to replace the starter gear with a metal one clean the teeth right off the fly wheel. It already had broken teeth so I would’ve had to replace it in a couple of years anyway So im having to replace more then I needed to Thank you for explanation on what went wrong on my mower Trying to teach myself about small engines.

[@BrucesShop]

Thanks for the info. I am trying to convert my 8HP genset to electric start. Video coming of course

[@GoKartsorGoneFishin]

Good info Willy!

My daughter brought me the starter from her 18.5hp mower, with the 16 tooth plastic gear, and worn teeth. According to the manual, it should take the 14 tooth metal gear. She sent me pictures of the flywheel, and it definitely looks like cast iron. The starter had a number on it, which matches the plastic gear. She has had the mower for a couple of years, and bought it used. I'm beginning to think someone put the wrong starter on it.

[@willyck948]

Hopefully, you get it fixed👍

I'm at a loss bought a older troy bilt 16hp hydro with the B&S vanguard and the aluminum 16t starter gear is rounded but everything I'm finding is either 14t or 16t plastic/metal any thoughts thanks

[@willyck948]

I haven't seen an aluminum starter gear myself so not 100% sure. I suggest looking up PARTSTREE.COM then use engine model type and code to trace down the specific part number.

[@fritzhellendahl5843]

Good!

[@Nuprem1z]

I have a 12.5 hp b&g model number: 285707 & type: 0115 - 15 parts tree doesn't have that type number on their data base. Are any of these gear types interchangeable by diameter (?) or how do I find out which of the 3 ring gear type fits my engine?

[@willyck948]

part number seems to be similar to 285707 0114 which is older L head vertical shaft synchro balanced briggs they usually ran a plastic gear bindics either Briggs & Stratton 497606 or Briggs & Stratton 495878 Plastic Gear is the same Briggs & Stratton 280104

[@musicheartbeat1451]

Would you have part number for Briggs steel gear

[@arnejuwe7544]

I’m making a racemower of my Westwood T1600 but my starter gear is always losing his teeth, how can I prevent this?

[@willyck948]

Check the flywheel for any damage / missing teeth, if its aluminum ring gear than it should take a plastic starter gear. You can verify part number for the starter gear at a briggs dealer website like PARTSTREE.COM I usually replace the entire bindics assembly as there's china parts that aren't the same as oem parts.

[@joshmanis9860]

How do I tell if I have a flywheel that uses a plastic gear? I got a motor that didn’t have a starter and I don’t wanna screw up the flywheel

[@willyck948]

If it has an aluminum ring gear than plastic starter gear is the way to go. I recommend going to Partstree.com then select briggs tab and entering model type and code to bring up the proper parts brakedown for the starter and gear

[@Try2-Imagine]

The number of teeth is the most important thing to match up. Most metal pinion gears are 14 tooth.. Most 16 tooth are plastic, but there is a metal one for older Roper riding mowers and the such.

[@kingpete693]

How to know witch one to buy ?

[@L1K2F3]

Are you still out there? I have a couple questions i'd like to ask someone that knows about Briggs starters and gears.

[@willyck948]

I guess I'm out there🤣 I'm more familiar with flatheads though. Best bet is searching by engine model. I like the partstree website myself.

[@misterbulger]

do you know the number of teeth on those?

[@willyck948]

I never counted teeth. Plastic starter gears are only used for alluminum ring gears. Steel starter gears can be used on either cast iron or plastic ring gears. Only suggestion is to match original equipment and double check the gear teeth clearance before attempting to crank an engine after installing used parts. The blower cover or valve cover should have model/type/code for parts break down information

[@spikey12121]

14 teeth on the metal, 16 tooth on the plastic

[@rickybailey7123]

Been nice if u gave part numbers for the aluminum ring gear ⚙ plastic starter gear 90% of people watching this need the gear part number I ordered the wrong 1 myself!! Well 2 more guesses I ordered the mettle 1 thinking I won't haft to mess with stripping it no more well nope wrong 1 lol !!

[@willyck948]

I recommend looking up parts using model type and code at dealer website Partstree is a good place to get oem parts can copy and paste part numbers from there if youd like

[@rickybailey7123]

Thanks for your reply I've not ordered the new 1 yet but will try what u recommended thanks bud 👍 !!

[@fritzhellendahl5843]

Good!
