OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Briggs and Stratton 450 series 148cc

My thought there was a problem with the starter cord..........
I will try to find another one, it has LW13 , guess that's the part no.
Seems a bit thin... but the mower has done heaps of work............
If anyone had one laying around.I 'll look first around Bundy.

I've got a few old B&S laying around. I'll check and see if I have one the same series. Do you think other series might fit if they are the same cc's?

Where did you find the number on it? I have only got one of that series but it is on a good base with catcher that just needs a carby clean someday so that one is out. I do have several others from different series but don't know if they would be interchangeable.

Good afternoon speedy. What is the Model, Type and Code on the cowling?
I have a 450 series Model 9T502, Type 0141-B1, Code 10082651 and just went to the Briggs and Stratton website to get part numbers. As they need 6 digits for the model, it was easy as adding 0 to make the Model number 09T502 with type 0141 in search.
According to my mowers reference, the part numbers for the Flywheel are 79968, which replacement part number for mine is now re-order part number 592370.

Link to my engine manuals is:-

Picture of my cowling and motor are shown below to assist.... Sorry, they uploaded upside down....



Hope these can assist.

I regularly use the Briggs and Stratton site to get manuals for individual motors, so you might want to save this link....

Some other series fit, I will check on B&S website.

The number is on the under side, but don't pull a good mower apart. There must be heaps of dead ones around. I will put an add on local gumtreee.
The guy at mower centre said he had a few , but it would cost $30 , a bit much for my friend
Thanks guys

Not sure what the local tip is like in Bundy, but it may worth a quick visit.

Thanks Bushy
The numbers are

I have the manual, just checking it out now.

that model no is 9T502, maybe obvious to the knowing...

Adding a 0 (zero) in front of a 5-digit Model Number is a thing you need to know with Briggs to make it a 6-digit number to search information on an engine....so, your search Model number is 09T502 with Make number 3152 (the first 4 digits) and you get your correct Parts Manual (link below) 09T502-3152-H1 .... :-)

Based on your motors Parts Manual, it's the same Flywheel as mine.
Just realised I had my original Flywheel number incorrect as 79968 and should be 799682.
My Tag line for my Laptop repair service is "Every day is a good day to learn". :-)
Hope you can find a replacement. Priced new ones at US$76.

Hi Speedy, Bushie and Aussietrev,
They're all interchangeable from a 9 or 10 cubic inch briggs. 148cc or 158cc motors basically. 200 series, 220 series, classic 35, sprint 375, sprint 40, quattro 40, 450 series, 500 series and so on just to name a few. They'll all fit the 450 series you have there. I have about 20 here, if you were closer i'd give you one to use and one to keep as a spare.lol

Thanks bigted,
I can find one up here with all that info.

Had an idea........... fixed it with a couple of steel straps and ss rivets.....
put it together and mowed the lawn...........
cheers

Speedy, glad it managed to cut the grass but you won't be able to get it tightened up on the taper and you are relying on the keyway to take the load, this can end up flogging the keyway slot in the crank. Keep looking for a replacement one, apart from the fact it could fly apart with fatigue

I've got flywheels here on old dead mowers. I'll see if I can get one off intact. I am going to be in Bundaberg on the 4th of April and could bring it over if I do.

Wow.... that's scary.... with the rpm of a lawn mower, I don't think I would be game to try that as a repair. I think aussietrevs offer is the better scenario, but at least you got the lawn down. :-)

"but at least you got the lawn down. :-)"

And still have both your legs :-)

Here is a flywheel from a 375 Sprint that I took off. It looks to be more substantial than the old one and doesn't have that big pair of holes near the edge that appear to have been the beginning of yours initial failure. $5 for my time and dropping it off in Bundaberg for you seems fair. PM me if you want it with address details. Will be in Bundie most of Monday morning on the 4th of April.

You are one lucky muppet. Wile it did hold up, I have no idea how your still in one piece. You cannot keep using this flywheel it is far too dangerous. There was a thread sometime back where a member had a broken flywheel on a Victa twin and was well advised not to try repairing it and NOT TO USE IT. Please remove the flywheel and throw it to the scrappy. It can be made into 3 new engines for Kias. We don't want any of our members calling an ambulance because they cut the lawn.
