Great video! It was a choice of $1000 for a new engine, up to $3000 for a new tractor. I replaced the gasket, changed the oil and new spark plug/filter for under $60.

That's what I call an informative, no nonsense accurate repair video

Very good quality, clinical precision! If only they had these videos when I was in high school, shop class, and garage tinkering.

Thank you for saving me $350 to fix my John Deere. I watched your video about 10 times before I opened my deere and at each step everything was as you explained. I got the gasket and sealant from Amazon, and the rest was just as you presented. This was great!

THANK YOU so much for making this video! My local 🚜 dealer wanted almost $500 to do this exact same job. Thanks to your video I ordered the things I needed and had your video for guidance every step of the way. And I really appreciated your providing all the torque specs for all the bolts. A couple of other DIY videos indicated they liked to add Permatex copper Spray-A-Gasket to the new head gasket, so I added that to all 3 gaskets (head, rocker arm cover, & exhaust) and I'm glad I did (I put one small scratch in the head scraping off the old gasket material and the copper spray gave that gasket just a little extra for that imperfection in the surface of the head). Another user showed a great way to gently but effectively remove all the material the razor blade can't get off: spraying the surfaces with WD-40 (or an engine cleaner) and using 400 grit sand paper to wet sand the remaining material off. That really helped get what scraping alone couldn't. Can't thank you enough for making this video! As Red Green says, "If the women don't find you handsome, at least they should find you handy!".

I really liked the video, very complete. Only problem that I noticed was that my engine was not quite as clean!

I'm back here after doing this in July 2018 to refresh my memory on the torque specs. Can't complain the job lasted 6 years (did not use an OEM gasket-Ebay). This time around I am tossing out that heat shield on the principal it will allow more airflow around the engine. Good luck to y'all out there doing this, very simple if you follow these instructions and it works.

[dalegray]

Thank you. I watched portions over and over as I progressed through the rebuild. When I had it all back together, it started smooth as silk. Again thank you!

You know what's great about YouTube... There's. A. Video. For. Everything.

This was a great video. I was able to completely disassemble and reassemble in one afternoon. I would only recommend converting inch-pounds to foot-pounds because most torque wrenches come in foot-pounds. Thank you for a clear and easy to follow video!

It is very easy to remove head without undoing the valve rockers! Just unbolt the head and pull the stem and head as one piece. Make sure you note that the stems are not identical! The steel one is the exhaust and the aluminum being intake. Be sure to always install the stem the same way it came out do not flip it end for end. It would still function but if there were any wear that was matched it is always better to install as it came out. Still check valve clearance. Gor those without inch pound torque wrench it equal 14-18 ft lbs of torque

Great video with great detail. My exact mower. 1st engine repair I have ever done. Went very smooth. No more smoke!

[terrypete]

Awesome Video, very helpful. I like that you also included the torque specs as they can be hard to find sometimes.

[muttlange]

Thanks for the great video! It helped me replace the head gasket in my 21hp Intek Craftsman lawn mower. It provided all the needed info to do the job. My mower had been burning oil for a few years so it was nowhere as clean as your demo rig . Keep up the great job.

[ryan]

Amazing video with all the details you need including torque specs. Thank you!

[darrell]

Wow. This is exactly what I was looking for. Excellent video instructions!

[seanwolf]

Awesome video. Gave me the confidence to do this today. Pretty easy.

[DavoShed]

That is the cleanest mower engine I have ever seen.
If my head gasket had gone before I have mowed the lawn at all I’d be taking it back.
Clinical repair? Oh Yeah 🤠

[ToddKrupicka]

I had this playing while I replaced the head gasket. Thank you.

[snarfsnarfff]

This is perfectly explained. Thank you very much!
