Thin is one of the best video on TH-cam. Right down to business! Well choreographed,well executed and well done! 😊
007, That is a strong statement. I really appreciate the feedback! - Stiles
Super video, one of the most precise straight forward presentations I’ve seen on YT with none of the unnecessary chatter and comments, just gets on with it for folk that are already good mechanics just need the sequence of the procedures. This gentleman is impeccably detailed from start to finish..
Michael, I appreciate the detailed feedback! - Stiles
You literally have the best videos in the world for fixing things. I did 1 side of my head gasket on this mower. skipped many bracket steps and other things. Head came off. Caked spark plug like mush from oil. Same head gasket problem spot as yours! Oil rushing in the cylinder smoking white 247. Now I’ll order from your link. Thanks so much man!
Tampa, You are very welcome, I'm glad to help! I appreciate the feedback! - Stiles
Great instructional video! It took me 9 hours to do it mostly because of the bolts that are under the engine. Would have taken forever and probably would have paid someone to do it without this video. Thanks!
Ford850, Very good! You are welcome, I appreciate the feedback. - Stiles
Thank You so much for doing this - I don't know that I would have tackled this job without such good guidance at hand.
Joe, You are welcome, I appreciate the feedback! - Stiles
Awesome video. Very detailed and not only shows taking it apart, but putting it back together.
Explorer, I appreciate the feedback, you are very helpful! - Stiles
This video was a big help, thank you for posting this up!
James, Glad to help, I appreciate the comment! - Stiles
Thank you for this video! I have a Kohler Command 25hp horizontal that I bought headgaskets for and they didn't say whether or not the wide or narrow side (fire rings) of gaskets went up or down. You confirmed it for me. Thanks again.
Dg, Yep the rule is the printing is up, or some do not have printing on them, then the wide side of the Head Gasket Flange is down (or cylinder side). You are welcome, glad to help! - Stiles
Perfect! Thank you so much. That’s gonna be tomorrow’s project for me.. this alone is worth a subscription 👍
Jack, You are very welcome, I do appreciate the comment. You do know to subscribe to a Channel, doesn't cost anything, right? LOL - Stiles
Wow amazing video and description. Genius
Tampa, I appreciate the feedback! - Stiles
Mate your a bloody legend same tractor as mine great help bud keep up the good work👍
Albert, I appreciate the feedback! - Stiles
I have a 25 horse Koehler motor on my 50” zero turn Cub Cadet tractor, that’s 20 years old. I need both head gaskets! Cost is about $1200. I was thinking of buying a new zero turn, but with the cost of new ones and now, I hear they are made by MTD, I think I’ll get the gaskets replaced. I’ve taken really good care of it, so everything else seems good. I’m a 😮72 years old woman and still do all my own yard work, edging, trimming, hailing dirt or mulch for a very large yard. They don’t make the zero turn tractor, anymore, but they put a steering wheel on the regular type zero turn. The mechanic at my dealer suggested I sell it for around $600. I’m torn on what to do. I’d go from a 50” cut down to a 46” to save a little $$. I thought of getting a yard service to mow, but that’s $50 a week or $1800 a year and going up, so that’s not an option. What would you do if you were me?
Gebhard, Staying active is what keeps us young, so I hope you keep doing it yourself! 20 years, sounds old, but its about the hours you have on the Mower. Lawn service people put many, many hours on their Equipment. I'd say based on what you said, I find a second opinion, get a second quote on replacing your Head Gaskets and keep your Old Mower. Let me know how it goes! - Stiles
$1200 sounds way high I could do the job for around $500, and would include a valve job as well. I know many people tell me I'm too cheap. Still $1200 sounds ridiculous.
26:20 i just got done watching up to the point in which you completed the right sode and when you were talking about removing the rockers, i was thinking to myself, if you put the engine at TDC then the rockers will be loose and you wont be fighting them when reinstalling. Then i get to this part, and im like ohhhh okay good he does mention it hahaha 😂
Aaron, Yep, you don't have to put the Piston at Top Dead Center, but then you have to overcome the Lifter Spring Pressure (for Hydraulic Lifters). To give the Cylinder and Top of the Piston a good cleaning, you should move the Piston in the Bore anyway. When done, leave the Piston at TDC. - Stiles
Thanks for your info!
John, You are very welcome! - Stiles
THANK YOU FOR YOUR HELP
JD, You are very welcome! - Stiles
Very thorough!
User, I appreciate the feedback! - Stiles
Very informative brother 👏
Lewis, Coming from you (I took a quick look at your TH-cam Channel) that means a lot! I appreciate the feedback! - Stiles
Thank you. Well done.
Ron, You are welcome, I appreciate the feedback! - Stiles
Thank your for your help
JD, You are very welcome! - Stiles
I just finished this same job on my CV730. The exception, I had a valve job done. I had checked the compression before and after. Cylinder #1 was 115 #2 was 117 afer #1 was 130 #2 was 160. Why the good cylinder increased so much more is beyond me. However I'm certain it needs rings as well.
Its on a Murray 40 inch cut. I'm sure Murray never used this engine on a 40 inch cut before, nore use dual exhaust. It was easier than trying to use a single muffler. Plus I left the the exhaust on until I removed the heads. Then put them back on after the valve job.
Bert, Ok, very good. All good information. I appreciate the comment! - Stiles
Luckily you had nuts on the exhaust flanges .Some Courage engines have torques head machine screws that limit options for removing them.I recently did this head gasket replacement and found it would have been a time saver to remove the engine.The left cylinder being lower to the frame will not allow easy removal oft he flange screws and almost impossible to put them back in to complete the job as there is very little room.
Phil, Geez, man, that is ugly. That is the worst location to use a Torx Head ( or an Allen Head for that matter) Fastener. Don't get me started on poor Fastener Selection and Use. Yep, my Kohler Engine has Studs and Nuts, a good choice because the Studs help you locate the Exhaust Manifold on the Cylinder. I appreciate the comment! - Stiles
I have a Kohler V-Twin thats blowing out of the valve cover vent. Could that be caused by a blown head gasket?
Good job and thanks for the post. Just want to add a coupleof things- Laquer thinner is oil based and isno good for gasket surfaces. I'm sure its no issue with the crushring gaskets but acetone or alchohol is best. The idle is way too low and that adj screw below the cable bracket needs to be adjusted. Also, I didn't see any exhaust pipe gaskets. Maybe they don't use them? Thanks again.
Glenn, You are very welcome. Yep, true, on your Thinner comment. I've always used Lacquer Thinner (or Enamel Reducer) on mating surfaces, because I have it readily available in my shop for painting. I haven't had a problem with RTVs or other sealants sticking to the surfaces, but you are right, hitting it with alcohol would be best!
Yes, Exhaust Gaskets are used. The Exhaust Gaskets are shown in the video at 15:22 when talking about the new Head Gasket. And lay the Exhaust Gaskets on the left and right Tires at 44:22 to stage them for assembly onto the Heads.
I appreciate the comment! - Stiles
Great video, doing heads on my scag and they are the same torque. Valves too, but going with permatex cuz gaskets are junk.
Dan, Yep, we like Chinese stuff 'cause its cheap, then we hate cheaply make stuff. I'd use the hardening Permatex, 1B (see link below). - Stiles
Permatex 80008 3oz Form-A-Gasket Tube amzn.to/4cf7Xe0
Thanks for posting. I have same engine. I see oil dripping from 2 exhaust bolts. I assume head gasket leak but there is no other sign of burning oil or rough idle. Just need to keep adding oil until snow season is finished in Ontario.
Eyes, You are welcome! Yep, most likely the Head Gasket. Can you feel back on the cylinder (or see) if the Oil is flowing from the Crankcase? One advantage is your Engine always has clean Oil in it. Just be careful not to run it low on Oil. Let me know how it goes! - Stiles
@@StilesAutomotive Your tutorial was much appreciated. I just finished the replacement on my GT1554. I do have a follow up question. I powered on for 30 seconds and I could see whitish (not black for a change) exhaust but some was coming back out where the exhaust manifold enters the muffler. Some was coming out the muffler exit port as expected but I was surprised to see the "backwash" effect. I think it was mainly affecting the right side which I guess is logical because the left side is quite close to the muffler exhaust port. On my machine, the manifold pipes enter the muffler in the forward direction and the exhaust blows to the left side. Your pipes drop downwards into the muffler but the basics are the same. Any thoughts?
@@Eyes_Open White Smoke in the automotive world is normally Water or Engine Coolant, our Lawn Tractors are air cooled so this is not Coolant. Could Water or Parts Cleaner, Carb Cleaner have gotten into your Muffler? - Stiles
@@StilesAutomotive Definitely carb cleaner. Just not sure why the exhaust won't all follow the suggested direction.
Your video is so informative that I decided to change a blown head gasket on my 25 hp v-twin Koehler engine. I removed the right head and changed the gasket with out a hitch so I decided to change the left head gasket as well. I went through the same steps but before replacing the head I discovered a pea size bearing on the mat where I cleaned the head. I don’t know where it came from and didn’t see any bearing’s on the right side when I replaced the head. I’m at a standstill until I find out where this bearing belongs. Do you have any comment on where this pea size bearing came from or where it may belong.
Thank you!
User-Z, Are you saying an individual Ball Bearing? Do you think it came from inside the Head, like from the Push-Rod chamber? I'm not sure here . . . I'd guess it is from the Steering Quadrant at the base of the Steering Shaft or something . . . - Stiles
This is the 3rd or 4th video of this same issue on the same engine family on a Cub Cadet. When I sold lawn and garden stuff in the 90s the Kohler was the best between them, Tecumseh and Briggs. Looks like Kohler pulled a Subaru with the head gaskets.
GeekBoy, It probably not a Kohler issue (although it could be) it is whoever manufactured the Head Gasket. I think the Kohler V-twin is a good Engine, However, I worry about the Plastic Gears. I thanks for the comment! - Stiles
Kohler shouldn't buy gaskets from this supplier, is a Kohler problem
Changed ignition coils, carb, spark plugs, air filter, and head gaskets and still getting white smoke it looks like its coming from the exhaust, also the exhaust turned red hot. Running lean? Maybe needs adjustment of the carb fuel mixture. What do you think could be the issue?
Mayo, You leave me with a few questions. First of all, "white smoke" is normally water or coolant, this is an air cooled Engine, which makes me think, excess Fuel. If you are burning Engine Oil, it would be darker, blacker, or grey. What does it smell like, Gas, Oil, Water? 2) When you replaced the Head Gaskets, did you see a bad spot like I show in my Video? So you know there was a problem with the old Gasket? Are the Spark Plugs fouling out? Is water getting into your Muffler? 3) Yes, running lean will cause your Exhaust to be hotter, also if your Camshaft timing is off. Let me know how it goes! - Stiles
I have the same mower with the same exact issue on the same cylinder. Was there a reason to change both head gaskets?
Gent, Yep, there is. The Head Gasket Set is cheap and you are 95% there to replacing the other Gasket anyway. It doesn't make sense to no replace it. especially if you don't have the "improved" Gasket. - Stiles
Hey I have a question about my Kohler engine where can I go get the torque specs for a PS ECV740-3019 and I have a 797 Kawasaki FX730v engine I need to get torque specs for the engine I have a 930m I need torque specs for engine
Sweet, I talked about References in my video (link below), let me pull them out for you:
kohlerpower.com/en/engines/manuals
www.cubcadet.com/en_US/operatorsmanuals
I haven't looked for the Kawasaki Manuals, I have a Paper Copy of the Manual for my ZX-10R. - Stiles
Data Plate and Sticker Location, Determine Manufacture Year, Model & Serial Numbers, Cub Cadet Tractor. th-cam.com/video/AZkyspJ-iuE/w-d-xo.html
Kohler has all the specs in their service manuals. See if you can find a kaw service manual for your engine, or call a kaw dealers parts department.
We have blown the right side twice. It looks like the problem is that the exhaust pipe is to close under that gasket.
Mr. Blanche, That is interesting. Are you using the "new improved" Head Gasket? - Stiles
@@StilesAutomotive I don’t think so. How long have they been out?
@@mrblanche At least a couple of years, i don't know about prior to that. Did you see the difference when I compared the old and new Gaskets in my Video? The new Gasket has more material in the area where my old one failed. - Stiles
@@StilesAutomotive Yes, the new gasket you showed was much beefier than the orginal.
How many hours are on that mower
Derek, 229.4 hours. I have a lot of woods and my mowing season is short. - Stiles
@@StilesAutomotive Rodger that thanks.
I wanted to add that there is a hole through the frame to put an extension to take off the exhaust 2 nuts.
Tampa, That is a good Tip, Yes, my tractor has holes under the inside Exhaust Tube Nuts, one hole on each side of the Tractor. You could put an 1/4" Drive Extension thru the Hole from under the Tractor, put a Socket on the Extension, then remove each of the inside Nuts. I used a Ratcheting Box End Wrench. I appreciate the feedback! - Stiles
I just refuse to only replace one side
Both have been over heated and when the other side goes they blame you and your business and how you cheated them
Phillip, I have always replaced both, I talked and show in the video the new improved Head Gasket Design, if that doesn't do it. The price to replace one side vs two sides is the same. Bill out the Head Gaskets, not as 2 Head Gasket Kits, but as 1 Head Gasket Kit (that contains 2 Head Gasket Kits). At the point you start to touch the Heads, 80% of the work is done, doing a 2nd Head is so minor. Thanks for the comment! - Stiles
@@StilesAutomotiveI had a customer who only wonted one head done and 4 months later other side went south
He blamed me for it
So now it’s both sides or none
Junk gaskets! No flame ring around hole for cylinder! Had to replace my 24 hp Kohler gaskets at 130 hours! I repeat junk!
Glenn, You would think Kohler would want to protect its reputation. The Head Gaskets are definitely a problem. I appreciate the comment. - Stiles
Congratulations. At 23.50 you over-torqued the head bolts by torqueing them TWICE. I see so many people do this on these repair videos, it blows my mind!! If you can't trust your torque wrench the first time, why bother trusting it twice?? Seriously, I took a course on torque and one thing the instructor stressed was to NOT torque the same bolt twice (at it's final torque value). Also, whenever you set a torque wrench to a new/different setting, you should pre-stress it by torqueing a "dummy" nut at least three times. That helps the torque wrench settle out at the desired setting. And finally, just FYI, when you are done using a torque wrench, set it back to the lowest setting possible on the tool and put it in its case. Torque wrenches should be calibrated annually by an accredited standards lab too, but not everyone can afford to have that done, so I can understand that. Otherwise, very good video.
