This is the engine I took off of a JS45 JD push mower- OHV engine. Im trying to find out what flywheels interchange with this engine.
This is a 12s502 0114 b1 engine according to the stamp on the housing cover.
When I look it up per B&S website it shows the engine to be a electric start engine- it is not an electric start- so the flywheel doesn't have the ring gear.
Does anyone have an idea as to which of the various OHV B&S engines the flywheels interchange? Im not looking to buy new
And the old one was broken in half- someone hit a piece of wood hidden in the grass!
Thanks for your help

this is the flywheel shown for that model, even though it has the ring gear, all you need to do is install the starter cup on it. which is super simple.

any idea if it interchanges with any of the other OHV engines in the B&S stable, or is it exclusive to the 190cc?
Im trying not to spend much on this and used mowers for cheaper then a new flywheel can be found around here.
Thanks

Well here is a complete list of engines where the 697610 is used. Since it is so long can't paste directly but is the file and it is 21 pages long.

Thanks, found a 173cc Cub Cadet today that matches one of the numbers in that list.
Picked up the whole mower for $35, im going to check the shaft size on the blade side- im guessing its probably the same.
If so im going to switch out the blade mount and self propel pulley , clean the varnished carb and put it on this old JS25 mower of mine.
I actually got it to run, so i'll use it instead of the 190cc Briggs, since it needs a helicoil put in the crankshaft for the blade.
Thanks again, Mike

another question concerning flywheels.
Has anyone come across a flywheel that did not have the puller bolt holes threaded?
am I missing something here, or do I need to run a tap in the holes, as so to screw in bolts for my puller?
The old flywheel had threaded holes.
ETA= Ok just found that Utube vid that Scrubcadet had post awhile back- Im going to give it a try using a bigger hammer this time, hope I dont break anything.
I tried this last night- it didn't budge, but I used a dead blow hard rubber mallet and pry bar.
I lubed up the crank last night after my failure, and I'll get out the BFH today and try again.

Yes you have to tap them. Apparently someone already had the old flywheel off before.
