Question about Briggs & Stratton Garden

How do you remove the flywheel on an old Briggs mower engine with no flywheel nut? Are they just press-fit on? It's the kind with the honeycomb type mesh over the top of the flywheel. Thanks.

    That's the part that confused me, I guess; the Sprag Clutch Assembly. I'll have to look again at how that piece comes off. Unless you also have a tip for me. Thanks so much for your time, Phil.

Hi, the flywheel is on a tapered shaft with a alloy key. If you hold the motor by the flywheel while suspending it by hand and have someone strike the top off the shaft using a brass drift and hammer it will dislodge from the motor. This is assuming you have un done the sprag clutch assembly from the top of the flywheel. Hope this helps, regards Phil.

    Hi, there is a special tool available but basically you need to lock the engine up. Do this by feeding a a piece of rope down the sparkplug hole as a piston stop or holding the bottom of the crankshaft in a vise with a rag if you have the engine removed. Then grab the sprag clutch with a strap wrench or a pipe wrench and undo it while been careful not to break the small screw lugs off the clutch. Regards Phil.

    Thanks again, Phil. You the Man! I've been refurbishing old mowers (and weed whackers and anything power equipment) that I get for free from anywhere I can and flipping them. Kind of addicted to it now. But every now and then I hit a snag and look to guys like you who truly humble me. I've been "giving it back" by sharing what I've learned on this site as well. Gotta love the "".

How do I fix a shear-pin on my B&S mower engine?

take the cover off the top of the engine. remove the nut that holds the flywheel on. take a wheel puller and take the flywheel off the sheer key is in the gap on the crankshaft. put the flywheel back on align the slots up and insert new shear pin put nut back on and covers. be sure the blades were not damaged. some people use a crow bar to pop off the flywheel and hit the crankshaft with a hammer. i don't advise it because you can damage the threads on the crankshaft. good luck

Engine turns over but wont start

It sounds as though you may have a sheared flywheel key. The keys are made of aluminum and shear easily if the flywheel is not tight. Remove top cover and flywheel retaining bolt/nut. Examine key for location with slot in crankshaft. If sheared, orient the flywheel slot and crankshaft slot so that a new key fits. Be sure flywheel and crankshaft mounting surfaces are clean and free of oil/grease. Tighten crankshaft retaining bolt/nut to 90 ft lbs. Flywheel posisition is maintained by friction between it and crankshaft.

What is the magneto gap for a 6HP Briggs & Stratton 12H802 series engine?

Briggs lists it as .006 - .010 on this 6 HP L-head engine. The .010 width can easily be attained by using a standard sized business card as a feeler gauge (and it doesn't stick to the magnets in the flywheel). I double up the card, loosen the coil and let the magnets in the flywheel draw the pickup legs in until they press on the card, tighten up the retaining screws (threadlocker is optional) and your air gap is set.

Backfires through the air cleaner

This usually means a bent or sheared key in the flywheel. Remove the shroud exposing the flywheel buy a 6" flywheel puller and remove the nut for the flywheel and attach the three jaw puller remove the flywheel and replace the flywheel key. The only other thing that causes this popping through the carb is a burnt intake valve this is a job for a lawn mower shop.

I think the key is sheared but how does it get changed,I have done it before but it was on a briggs & stratton engine,this has a tecumshia engine.

Remove the starter rope assembly, remove the outer casing. When the flywheel is clear, you can do one of two things to loosen it...Remove the flywheel nut and the cup, take a nut of the same size and place on the threads. Turn down only a few turns, lift the flywheel with one hand and tap the nut with a hammer in the other. Once it is loose you will see the flywheel key. Good luck...Lee

Briggs +stratton lawn-mower engine type 0170-01

hold the engine in one hand and take a small hammer and tap the crankshaft nose on the flywheel side with the nut removed. the inertia of the flywheel and the rest of the engine moving should pop it right off. if the engine is still on the mower, drain the oil first.

The flywheel pin needs replacing on 3.5hp briggs and strat.engine

Take off the top sheet metal , there should be a nut & spring washer that will have to come off, they will be tight. Put the nut back on a few threads, use a prybar to put some upward pressure on the flywheel at the keyway side, while hitting down on the nut with a block of wood & large hammer. This should pop the flywheel loose from the taper shaft, replace drive key with ALUMINUM key!!

An impact wrench is sometimes necessary to get the nut loose.
