How to Change Piston Rings - Briggs & Stratton V-Twin Engine

- In this video, I show what it takes to take off a Briggs & Stratton V-Twin 25hp engine, take it apart and change the piston rings. While you are in there, inspect everything and you could service many other parts (remove carbon deposits, do a valve job, etc...). I re-seated the valves not long ago, so it is in pretty good shape already.

People who don't fix their own things just do not get what people who do fix things feel after you accomplish something. I was very fortunate back in the '80s to meet some great friends. I used to race and I never really did my own work. My good friends that I met at the track were all mechanics they all worked on cars or trucks and I even have two friends that are engineers who design military aircraft. When I need it something done on my car I asked my friends could they help or do it for me. They told me that they're going to teach me how to do my own work. It was a year later that I was tackling all kind of different things. I even cracked a head on my pickup truck bought the shop manual spent one night reading it the next day taking the truck apart and the following week putting it back together. That truck lasted 10 more years after I fixed it. I'd love watching people do what you just did. A lot of people would have not done that since it really didn't seem to bother the way it would cut. But when you fix things you want your things to work right.
Over the next 30 years I pretty much fixed just about anything that breaks around the house. I fixed washers dryers furnaces even air conditioning.
Since I'm retired what I do is fix neighbors and friends and families yard equipment and some people's cars not as much as I used to. I spend my money buying tools I don't want to be in a situation that a simple tool could fix faster.
After watching you fix this mower a good friend of mine has a big lawn tractor that the engine needs rebuilding. The motor itself is not broken it's the rings. After watching you that gives me the confidence that I know I could do it myself now.
Thanks for sharing your knowledge.
my favorite kind of video and what a great job and a pleasure to watch it , thanks for sharing
Fantastic....Its been 20 years since I opened up a small engine case and this vid popped up. A full refresher course. Well done..thank you
Glad it helped!
Making a note, if you use lock-tight on your connecting rod bolts, use the BLUE and not the Red. Same for your sump bolts and motor mount bolts.
Using the Red lock-tight, you'll break those bolts!
By in large, very good video for a flat V Twin Briggs! Thanks!
I use blue all of the time👍
I haven’t got the exact engine as this one, but I tell you what, this is a fantastic video! And it’s helped me no end as to follow the process to do this job myself! Very much appreciated. Thank you 🙏 Oh and wish me luck with my strip down 😂
Howd it go?
@@SeanHomanSilvyHD thanks to your video, it went like a dream! A fair amount of money for Rings and Gasket Set, but way cheaper than a new engine. And both cylinders are showing almost 9 Bar (130 psi) now, and it’s running as sweet as a nut.
Extremely helpful! Thanks
Excellent quality! Thanks!
Very good video explaining everything clearly for our 'my understanding.
Lol I have done this many times to my mower. Always worked out, tell this time lmfao. Watched your video to double check myself and yep I did it and still no start. Time to put her out to pasture
Amazing thoughtful video thank you
Great content. Do you have a part number for the rebuild kit
Great video thank you For sharing my question is the rings gave special position? Thank you
When rotating the governor shaft clockwise and tightening the lever the lever must be in position of full open throttle. I think that is also clockwise.
Coming back to watch later when i eventually do the one at my place its only got like 300hrs but its had a hard life
Nice job.
Very interesting !!
Hello! Thanks for the helpful video. 👍👍👍 Could you tell me is it possible in Briggs&Stratton Vanguard to extract the pistons with their connecting rods from the inside - through the crankcase, after removing the crankshaft? This is in order not to remove the cylinder head. The thing is, I need to swap crankshafts from one B&S Vanguard 14 to another B&S Vanguard 16. Both engines are in good condition, crankshaft replacement is required due to the different shape of the tail section (cylinder and cone). Changing 4 cylinder head gaskets is quite expensive. 🔧
Thank you very much!!!
15:31 What about the cam shaft timing?
Nice video, how much did all the parts cost you? Did you just reuse the head gaskets?
Thought you might have mic'd the cylinder for wear and maybe checked ring end clearance.
I'm looking all over the net can't find this kit for my 24hp motor. Any help?
Can you please send me the link of where you got the piston rings from thanks
Glad to see you posting again :) Great content s always. 2 questions, 1. is there an ideal speed to hone a cylinder wall? 2, If you get damaged threads on the bottom of the crankshaft where you attach the pulleys, whats the best way to go about trying to get a bolt back in if the first few threads get damaged (In my case my an air hammer)? Love the tutorials!
Thanks for the compliments! Honing a cylinder wall is recommended at a "medium" speed. For your crankshaft, I would first try to retap it and see if you can get the bolt started. If the bolt threads are damaged, I would try to rethread it also.
How much torque u put on the piston bolts??
I need help finding the parts to rebuild the moter
Where did you order the rings from can you send me the link for jt
Where the old ring seized up? Or were they just broke?
❤
'the drive pulley will drop'. Sometimes but I've had to cut a couple off.
how many pounds of compression should it have??
The flying insects are terrible to night in West Texas and I have given up working tonight
should have shown have the rings need to be turned so gaps are apart alot peps dont k ow about that
How long did it take to do this job
does anyone know where to find piston rings i have a 4.5 hp 190cc b&s engine and the oil ring is bad but i cant find a set for my motor.
Need engine model number. watch this to determine where it's located on the engine > th-cam.com/video/-ZumMk70hKo/w-d-xo.html
Put the full model number in google and search for a parts list.
Find the piston assembly section and the ring set, note the *exact* part number for the ring set.
Enter that part number in google and have a field day shopping at various sources!!
(Be absolutely certain before buying that it matches the P/N stated in the list exactly, or that it has the same number included in the list of other P/N, whether it's OEM or aftermarket) GL
When replacing rings do they need to be ground to size?
You have to check the gap on the rings to be installed. To do that slide the ring inside the cylinder and use a piston to push it down about half way into the cylinder. and use a feeler gauge to measure the gap. Refer to your specific engine specs to set the hap. If the gap is to small, when the engine is hot, the rings will scrape the cylinder walls causing scoring or they will break up and do some serious damage. When the gap is to big, you will have a blow by ( pressurizing the crank case), excessive smoke and loss of power. Hope that helps.
Does it not matter which way the rings face?
Did you seriously just not check the ring end gap on the new rings before install? Wow.
