Nice video, really shows the process clearly. I'm probably in the minority but I am not a fan of the Kawasaki eccentric adjusters. I much prefer the standard locking torx screw on the end of the rocker. The problem with the eccentric adjusters is they move and change the setting when you tighten them. I noticed when you tightened the first one your gap got smaller as your feeler gauge slipped out and I doubt you would have been able to re-insert your feeler gauge. I sometimes have to try to predict how much the adjustment is going to change and then misadjust by that amount so when tightened it is within spec. It's a lot of trial and error. These lock nuts are also supposed to be torqued and it is impossible to get a torque wrench on the bottom adjuster on the cylinder with the nuts on the bottom. I ended up using a crows foot on my torque wrench. The locking torx screw style are just so much easier IMHO.
@@joelmollenkopf3767 Yes, you are correct. But... it also depends. If you keep the crows foot at a 90-degree angle to the torque wrench there is no change to the torque value applied. With the 10mm flare nut crows foot I used, had I used it in line with the torque wrench I would have had to set the wrench at 6 Nm to get the required 11 Nm of torque.
I had my JD Z540m with Kawasaki serviced by John Deer. I've had the valves adjusted at 200 hours and again at 368 hours. (JD recommends every 200 hours adjustment.)Both times 2 valves were out of adjustment and 2 valves were good. What keeps causing the out of adjustment. Thank you for the video. Blessings to you.
Thanks so much!! Question: I'm doing my JD X300 clearances and the shop manual says to set them at 0.05 mm. Then it says the *Valve Clearance (when cold) Inlet, Exhaust 0.10 ∼ 0.15 mm.* Why am I setting them to 0.05 mm first? I'm already doing this with the engine stone cold. Can't I just set them to 0.13 mm (middle of their specified range)? Thanks again...
I have john deere x350, i cant find anywhere in manual how much clearance is needed for those v valve. Could not get any help from local john deere too. Anyone knows about it, please let me know.? Thankyou
Absolutely with a genuine Kawasaki rocker cover gasket. Get the old one off carefully not to damage the aluminum surface and replace it after you're done with the work under there. An oil leak can turn into a big fire really quickly once it hits that hot exhaust header. I actually thought of mounting a dry chemical fire extinguisher on my mower just in case. I don't know if they make a foam extinguisher but would be nice.
Hi mowermedic1! I have a 2007 exmark turf tracer that has a kawasaki FC420V engine which runs and starts just fine but has gasoline leaking into its exhaust/muffler. Neighbors and friends say that it could either be a stuck valve seat guide or a cracked engine head. I was wondering if you could maybe tell me what the problem most likely is if you had to guess what it is. If anyone else knows what the culprit might be as well, I'd be glad to hear it. Thanks in advance.
Amazing instructions; your teaching will help me and others learn a adjustmenting valve. Again, thank you and God Bless.
I work on small engines here and there but I don't think I'd ever figure that 1 out That's a great informative video
Awesome! All other videos show taking about the top cover and turning crank to TDC and doing the adjustment
Don't you wish all small engine valves were this easy to adjust! The scribe line makes putting it back to where it was a snap too.
This is fantastic! Could hear that my engine was “off” somehow. So well explained. Much respect and thanks from down under 👍
FIRST watch this video because it is the best demonstration of a small engine valve adjustment
TOOLS: 10 mm wrenches or a 10 mm wrench and a 10 mm socket
.004 feeler gauge. (better than manufacturers recommended gap)
Replacement gaskets or silicone gasket sealer
1 Remove spark plugs to make the engine easy to rotate
2 Remove the valve covers
3 Roatate the flywheel by hand until one valve is fully open then adjust the CLOSED valve as follows
4 Loosen the rocker arm nut then rotate the bolt until the clearance is set
5 Hold the bolt and lock it in place by tightening the nut
6 Verify the clearance and adjust if necessary
Repeat for each valve then reassemble with new gaskets or silicone gasket sealer
question from a newbie.. . Does closed valve mean the valve is at the top and fully open mean it is down?
@@dukemanvillle Exactly.
What do you mean exactly please? @@danielebrparish4271
I have x350 john deere from Australia, is 0.04 clearance for both inlet and outlet valve?
@@NeymarjuniorA Yes.
You are giving us great info and tips. Thanks buddy!!
Thanks!
That is a super easy valve adjustment on that kawasaki engine thank you for sharing jeremy 👍
That’s really a great way to do it and so simple
Great pics and explanation J.
Good one, Jeremy! Pretty interesting cam-actuated adjustment. 👍🔧
Great camera work 👍
So glad I found this as my golf cart has this same setup. Thank you

Crows foot wrench will change the torque value so be careful

Excellent video
Big thankyou. Just discovered this style on a john deere
Awesome, saved me thousands of dollars
Nice video I learned something else and new today thanks so much!!
Great detailed video my friend. Yep I saw that Stihl feeler gage LOL I use that same one a lot also.

Oh my goodness!!! Thank you sooo much for this video! I paused halfway to comment. Hoping you show how to gap spark plug too. 🙏
You are so welcome!
Great video! I have a Kawasaki FS on my zero turn. Thanks!
Thanks for the lesson of the day. I honestly dont think ive ever come across that design. Is it only unique to Kawasaki?
Thank you sir
Thought I was right, but thanks for confirming.
Thanks for the Great Video. I’ve never seen one like this. So eventually I’ll run into one and I’ll already know
Thx.Good video.Kill background “noise” as a suggestion
Is this the same for the kawasaki FX651v model
Thanks so much!!

Interesting
How do you get the engine on tdc
Is 4/1000 spec for intake and exhaust and is that when it is cold or warm engine?
Should have listened - cold 😂
Would have been nice to see where you rotate the flywheel to since that is an important part of the procedure.
You don’t have to rotate it at the fly wheel. All you have to do is put a wrench on the bottom of the crank pulley.
What the gap? 4 on intake, 8 on exhaust?
What was the setting????
I like this system a lot better than the shim system or the screw and lock nut on the rockers. What I don't know is which Kawasakis have this system.
How often?????
Will this work for all Kawasakis?
How do we find the top dead center on these?
I am trying this right now. But for some reason, the nut won’t tighten back up. Any suggestions?
I have john deere x350, i cant find anywhere in manual how much clearance is needed for those v valve. Could not get any help from local john deere too. Anyone knows about it, please let me know.? Thankyou
Will that gasket need to be replaced?

I have a stand on mower with the Kawasaki 600 . It has 230 hours on it and runs great, but how many hours should I do this? Thanks!!
Kawasaki fs600 manual States at every 200 hours to check this I'm approaching 1,000 hours currently at 990 I have never done this I'm about to do it
What is the interval for adjusting valves? How many hours is normal?
too many factors to give a definite time frame
The shop manual for the FS600V says every 200 hours. That's on a John Deere lawn tractor, X-370.
👍👍
Fx730v people are telling me to go a quarter inch past TDC, is that true? Please help..lol, thanks!!!
Is the fs651v this style?
Yes
@@THEMOWERMEDIC1 much obliged.

Needle and seat failure inside carb
@@THEMOWERMEDIC1 Thank you very much! Will look into fixing it! Greatly appreciated!

Articulated adjustment
No not quite. It’s operated by a cam lobe
Eccentric shaft adjustment. 👊
Tighten those nuts a bit more. Better yet use a torque wrench if possible.
What a stupid design set up! What's new when it comes to Mower engineering though....
