how do you put new rings in a briggs 10 hp vertical shaft engine? can i just pull the head and cylinder?

Question

could i do it in the tractor or what?

Answer 1

You actually need to remove several items to redo the rings in your Briggs, for starters remove the engine from the equipment.
I know...I know nothings simple anymore, you then have to remove the bottom cover from the engine. This can be triky I recomend that a professional does the rebuild. But if cost is a Issue then please try to find a Manual first and read thorgh it because there are problbly several steps I am not covering because each model of engine through the years is diffrent. one you have the engine apart

1. remove the square keyway from the crankshaft of the engine

2. remove the bottom crankcase plate from the engine/use caution because prying on this case may break it, they make them out of a magneseum or aluminum material so it breaks easy

3. becarefull of all the internal parts you should see a plastic gear inside that splashes oil up the cylinder to keep in lubed be sure this is in working order or your hard work goes down the drain when you restart the equipment.

4. locate the connecting rod that hooks the piston to the crank and remove the 2 bolts that hold it to the crank.

5. remove the cylinder head and drive the piston out of the block at this point you have access to the piston and can re ring it. but this is only half the battle because you will want to hone the cylinder at this time. the cylinder on all most all modern small engines is part of the crankcase.

6. buy a ring compressor and some engine assembly lube at this time. install the rings and lube the rings and the piston at this time.

7. use the ring compressor to colapse the rings and then tamp the piston back into the cylinder.

8. rebolt the connecting rod to the crankshaft, this is where the manual is helpful because I do not know the proper bolt tightness for the connecting rod. too tight and you can over stress the bolts causeing the bolts to shear off while the engine is in operation. Too loose and the vibration from the engine could cause the bolts to back off and the connection rod will fall off the crank, in either case I recommend new bolts and the proper tightening specs.

9. reinstall the crankcase cover carefully and torque those bolts, a new seal for the crank in this cover would not hurt.

10.reinstall the engine in the equipment. install fresh oil in the crankcase, at this point it would not be a bad idea to disable the ignition by straping the ignition wire to the side of case[don't hold the wire unless you like getting shocked] and crank the engine over for twenty secounds to be sure that the little oil gear in the case is throwing oil everywhere in the engine to prelube it, this will also roll the engine over without starting it giving you a chance to see if everything is rotating smoothly without fireing the engine. afterwards replace the ignition wire on the sparkplug and start the unit. It also might be a good deal to rechange the oil once after a few hours of break in time to remove any contaminates you might have introduced from homing the cylinder.

Answer 3

John m's pretty right, though you'll have to take the stack pulley off to take the sump off (bolt way down that hole)

When you go to take the sump off, tap it so to break the seal.


The must have part is the right torque numbers...... too tight and it won't just stress the bolts on the connecting rod endcap, but probablly rub so tight on the crank, if it is able to be turned over, the rod might soon seize to it.

Too loose and the rod will plop on the crank and soon break it or the endcap.

Answer 4

why do you need to put new rings in i never had to do that to a briggs engine i think you have i different problem what is the reason why you want to replace them

Answer 5

The jug is formed with the base
you will have to take the base apart to change the rings

Answer 6

you sorta cut to the bone, but yes. with new gaskets
