Don’t understand why people don’t clean engine before tear down. All that junk getting in engine.
5-stars...Excellent video! I recently replaced both head gaskets that were failing on Kohler's V-twin SV725 (24hp) Courage engine powering my Husqvarna riding mower. 9-year-old mower (looks like new) only 210 hours, but recently noticed hiss sound @ shut-down (tell-tale sign of failing head gaskets). Before I attempted repair myself, I watched a couple UA-cam videos on this...but Mustang Mowers video on this repair is the only one you need to watch and it's the BEST! Clear, on-point, concise and super-informative. Great job and thanks for all the intel.
Very good PM'S, THANK YOU! VERY INFORMATIVE INFORMATION,NOW ILL PAY MORE attention TO DETAIL ON MY MOWER
Great video....like how you explain everything. Just subscribed to your channel.
Thank you very much. Stay tuned. There will be more.
My 23 hp kohler is clean regular maintenance & head gaskets still failed poor design from factory thanks for the video 😊
It really was a poor design. But, Kohler has done a good job, in my opinion, with the fix on replacement parts.
I found some no name gaskets that already had the improved gaskets. Not sure if the aftermarket came up with the fix first or not.
Good video with great info on why you have to keep these babies clean. I replaced the head gasket on the one I bought used and it was completely plugged! Good to know it requires this kind of maintenance. I'm hoping that having stopped the oil leaks from the valve covers I can keep it clean by blowing or washing out the space without having to tear off all the sheet metal baffles--a real pain on my Cub. Oil in the grass and dirt makes it almost impossible to blow out with compressed air.
Thank you. A good shot of compressed air will go a long way. Stopping oil leaks is super important also.
I just bought a used zero turn mower for $500. I found an engine maintenance kit at Atwoods for $60. It comes with oil, spark plugs, fuel filter, oil filter, and air filter. I'll also get some Simple Green and a brush to clean it after seeing this.
This is a good reason to power wash a few times a season. Sometimes even with cleaning you still have problems.
Mine blew out at the same spot.
Mine blew out at 130 hours. Replaced with OEM gaskets , same as I took off. lasted until 332 hours. Emailed Kohler and asked them if they had an improved gaskets yet. Said I didn’t feel I should have to buy parts again for such crappy gaskets. They sent me a set of the new style gaskets , no charge. These gaskets with a flame ring around the cylinder hole should last the life of the engine.
The new style are definitely head and shoulders above the old. It's been our experience that Kohler has done very well standing behind their product.
Plus gas leaking on mufflers causing a fire and oil just helps it burn better
The oil sump cover leaks onto the cylinder and attracts dirt
New style gasket is great
B/S cam shaft problem nothing change, same junk
this is a great video man and will help me a lot. I'm having an issue where when i try to turn it over, it sounds like its trying hard to do so then suddenly dies, and air of some sort escapes out the right side near the spark plug. its like a hissing decompression sound that lasts a second or so. i replaced the spark plugs that were very black. Air filter is clean. Gas was in there all winter, but i ran it for 5 minutes 2 weeks ago and it seemed fine. Oil needs to be replaced badly as thats something ive neglected. i fear its a head gasket. do you have any ideas?
If you can hear air hissing out by the spark plug, that's pretty tell tale that the head gasket is bad or something much more sinister has happened. I would check compression on both cylinders to confirm that. If the fuel that was in it all winter has any ethanol in it, that could be part of your problem as well. Ethanol is bad stuff and does not do well sitting for any length of time. Hope this helps.
@@MustangMowers Thank you so much for the reply man, i greatly appreciate it. I'll start with a compression test and work my way from there! And yes, im fairly certain my gas has ethanol in it. The engine sat for maybe 1 1/2 or 2 months without being ran i'd reckon. Never had a problem before like that but i usually put in some sea foam, and i think i neglected that this year.
Best to replace both sides and clean engine before it’s worked on and after. Heads are warped for sure and need resurfaced
@philliphall5198 I don't disagree with you. It is, however, up to the customer and what they are willing to pay for. I do prefer to do both sides and if this were my equipment, I would have.
Thank you for this, very helpful. I think I have the same issue on the same cylinder. Should I do both gaskets at once, or just save the other for another day?
You have to pull the shroud off and remove the intake to get to one, you may as well do both at the same time so you don't have to tear into again down the road. It's personal preference really, but if it were my machine, I would go ahead and do both.
@MustangMowers I pulled off both, they were just on there with rtv. I ordered some aluminum covers as they were same price as composite covers. I heard they are a bit more reliable
Great video. Informative and interesting. I have the same Kohler 7000 engine . There is oil leaking from the valve cover area. I wonder if the head gasket is blown?
Not necessarily. Valve covers have a tendency to leak on their own. Do you have a loss of power under a load?
@@MustangMowers Doesn't seem to loose power under load just oil leak. Mower once shutdown when pto was engaged.
@@edthompson1727 There are a lot of reasons for it to shut off when you kick the PTO on. It sounds like you just have a leaky valve cover. Just like in the video, if you leave small problems long enough, they will become big problems. Valve covers are easy to reseal. Just get some high temp RTV and pull the valve cover off (should be 4 bolts) clean the mating surface real good, apply the RTV, let it tack up (about 10 minutes) then put the valve cover back on.
Okay thanks for the insight.
With a little research like I did you'll find out the Kohler 7000 series engines visit a repair shop a lot less than any other brand..
I’m finding oil on top of my intake manifold. Specifically between the two high points. Could that be a gasket as well or does the intake manifold need to be replaced?
Shoot some pictures of what you're talking about and email them to mustangmowers41@gmail.com so I can see what you're talking about. I should be able to tell.
Im about to swap my head gaskets out and i noticed the new gaskets have 2 rubber rings in each package. Anyone know what those are for cause the heat would melt them quickly so im at a loss here
They are your intake gaskets. I’m sure you’ve figured this out by now
I am doing the same thing what do I clean the head with?
We use a gasket scraper to clean off all the mating surface. If you have any stubborn spots, you can use something a little more abrasive, but, be careful not to take off to much of the surface. Then right before I put RTV on, I use a rag and some solvent (carb cleaner, brake parts cleaner, etc) and make sure all the oils and stuff are removed from the gasket surface.
what kind of torque wrench are you using.
Snap-On Digital.
Hey I have a question how do I find the torque specs for my Kohler engine I have a PS ECV 740-3019and I have a 797 Kawasaki FX 730v engine I need the torque specs for the engine
Is there a specific torque setting you're looking for or do you just want an overall torque value for the entire engine?
Mustang mowers. Please can you tell me what kind speciation is ajustment the valves. Intek and exhaust on this engine please thanks!
Kohler says 0.005 in for both the intake and exhaust valves.
@@MustangMowers thanks!!! Great video and good Information!!!. Gracias!!
@@MustangMowers please do you think is possible can you share the item for gasket head by 24 hp Kohler engine series 7000 . please I will be grateful! Thanks
I don’t have a torque wrench that measure in. lbs. only in ft lbs. my question is, first torque would be about 16ft lbs and next tighten down would be around 30 ft lbs. should I just get close to that?
How much do we tighten the rocker arms?
At the end of the day, as long as you're close I think it will be fine. To quote Taryl "it's not a spaceship, it's a lawn mower." Nothing has to be exact. When you get the valve lashing set right, tighten the retainers down enough they don't come loose. But, if you do the way I showed in the video, the lashing doesn't change so you don't have to reset them.
Nice video but you take the tourque stuff a little to serious lol, I'm a small engine mechanic at a shop and I change them all the time you don't need a tourque wrench just snug each bolt up nice and tight. Like even when your tool said you went to 390 there was zero point in loosening it and bringing it right to 370 if you had of left it alone it wouldn't of made any difference
That new gasket looks like it was designed to act as another cooling fin. It looks like it hangs outside the mating surfaces.
That was my thought as well. It's a much better design.
Any one knows how much a pair of this same kind of gaskets cost?
$20
People just refuse to properly clean there mowers and over heat them and head gasket failure
They talk trash about every brand and it’s never there fault
An ounce of prevention is worth a pound of cure.
How much should something like this cost to repair at a shop?
It really depends on the shop labor rate. Our shop charges $90/hour and I'm told that's cheap. You can bet on a solid 2 hours on this if you do both sides and don't run into any issues.
That would stress me out if my mower looked like that. Lol.
It would alarm you to see what gets dropped off at the shop. Lol
Looks like a piece of construction equipment, not a lawn mower. Fire the operator stat. Oil attracts dirt, dirt pulls oil, repeat.
Somebody worried about oil all they do put gas in ride it till it blows.every mower I seem to get take a hour or so just cleaning the engine always covered in oil.
The struggle is real.
This looks like a quick fix. If I’m doing this repair, I would have went ahead and replaced the valve stem seals and resurfaced the cylinder heads.
I don't disagree, but it's all about what the customer wants to pay for.
Dirty engine = head gasket job
I just did a cv20s that had ingested a screw and bent the intake valve. New valves, valve train and gaskets. Bled the lifters, Cleaned carb and reassembled.
Runs like a champ. Now theres your dinner. Taryl
And you didnt set the valve lash either. Yu suck
I have a serious question for y’all I am in need of a ignition coil for my Kohler PS-KT740-3029 and I just can’t seem to find out exactly what the number for the item would be like if I’m trying to find it on eBay anywhere‘s with buying it from the dealership I’m pretty sure it’s digital but I’m still not sure about that if anyone can point me in the right direction possibly on eBay and help me find one I will be so so greatful. I also have the spec number If needed that looks like the same motor I have I have a 2014 bad boy with a 54 inch deck. With the Kohler motor I just need to know what the numbers would be like for example I know there’s one on eBay that says it’s for a KT 740 and one set of numbers are ‘32-584-24-S’just for example Please Help
John, I can look that up and give you a part number if you want. Is it the #1 cylinder coil or the #2 cylinder coil? There is a difference.
It’s crazy watching this video this is the same mower that I have mine is a 2014 bad boy model number KT seven 40-3029 and I ordered one coil off of eBay.. it’s part # Is 32-584-09-S but I had no idea that there was a difference in the coils that boy didn’t even tell me that one but I know one of my cylinders isn’t firing and I am kind of hoping that it isn’t my head gasket now that I’m watching your video again because every time I pull the PTO my mower wants to bog down and die out whenever I run through some big grass or just running it through regular grass with the deck raised but I even did The valve clearance adjustment but I really need your help because even after I put the new ignition coil on I’m still not getting both cylinders firing because when I pulled the spark plug off of the right side and that is the older ignition coil but it was running or working before that coil and I have the newer one on the left side if you’re looking at the mower from the back and I pull the spark plug on the right side it will stay running but if I pull the left side spark plug it will shut off and I also have new spark plugs as well as a brand new battery and brand new blades and please if I have to pay you for some info to help me get this right or give me the left and right part number or what am I doing wrong here I would love to be able to possibly get a phone number for you or you could give me
Phone call or message or text me with that info my cell phone is 504-295-5079
@@johnkirby5570 I will be in the shop on Tuesday morning about 8:30 central time. I will give you a shout when I get in if that's cool. Feel free to give us a call with any questions you have 918-443-9393. I am going to ask you for the mower serial number so I can make sure I give you the correct part numbers.
