That is one clean 757! I’m rebuilding an old 737 right now and this video helped big time with the wiring harness. Thanks!

I now have other issues with my Z757 and that is how I ran across your video searching for help in solving my issue.

This guy was very through did a excellent job on replacing the motor . We need more good videos like this to show viewers all the things that they need to know to do it right.

I did a 23 hp vanguard repower kit as a cheaper option and couldnt be happier....only difference is rewiring the voltage regulator and i have a aftermarket pto clutch where i had to make a shim for it to fit perfectly. Great video

Great detailed instructional video! I ordered a new engine from Carrol Stream and swapped it today. I have never done this before and it worked perfectly. Much more helpful than the 3 min swap video on the company’s website.

Roger they let me know it will ship separate . Thanks great video

I had the same thing happen with a deere z665 24 hp kawasaki... A mouse had made a nest under the plastic shroud and packed grass around the cooling fins. I took mine apart and yes the push rods on cylinder number 1 was bent where the grass was packed. The valve seat was moved so i replaced one head 2 push rods head gasket exhaust gasket intake gasket and valve cover gasket. In parts all was just over 300.00 dollars. I also drilled 2 holes on the shroud and installed 2 plugs for inspection covers. That was 200 hrs ago and still running good...

excellent Video, Ty

Some sites say you should replace the PTO clutch when changing a motor. Don't know enough to make a call on that, but raise it as an issue for smarter people than me to explore.

Thank you for this detailed video. I’ve got a John Deere 717A with a Kawasaki FS601. I’m assuming order to upgrade to an FX600V, all you’d need to do is swap over the starter & voltage regulator from the old engine to the new one?

I have the exact same mower and the Kawasaki engine too. I had to do a head gasket and valve adjustment, plus install a hela-coil on the head. It continually backfired when turning it off. Found out I needed to leave the mother running at a faster speed when shutting down so the extra fuel would be burned and then there would be no backfiring. Also, I left the heat shield off on the right side because grass and weeds get trapped in there, and blowing it out will NOT remove it. Therefore, the cylinder gets hotter and also will not have the airflow it needs to remain cool. You obviously have experience in motors and rebuilding them. This was my first motor since high school and that was in 1974 with a Briggs and Stratton lawnmower engine single cylinder. You did a great job in your explanations and demonstrations.

How do I change my fan from my transmission? Need your help

I have the same mower and am Having power issues related to the hydraulic motor. Had the filter changed and hydro oil recently and that didn’t fix it. Left rear tire has less power than right rear. Affects turning and going up hills. Any suggestions??? Gets worse when the engine is warmest.

Would you sell the carb off it?

Can i ask what model from carol stream you purchased for this swap? Was it the FH721D-S08?

Hi, some questions. First is you mentioned the fails that the original motor can experience. Most importantly the cooling issue of the heads which can cause the slipped valve guides and subsequently bent pushrods. I see that the new motor doesn't have the access panels on each side of the front black plastic shroud, same as the old motor, that allow for blowing out the front of the head cooling fins. Has Kawasaki addressed this on the new motor? If not, I see that the same issue of dust and debris collecting in the front of the heads/cooling fins will be an issue. Second thing. What did you do with the old motor? I am trying to find an original carb for this motor. Kawasaki no longer makes the carb and there is no superseded model. JD claims to have them but huge cost. Nice video, thanks.

How's the new engine running? Power good? On mine it feels like it is a little under powered. Might just be me but it seems the old engine was a little stronger when getting into grass that's a little heavier than the average weekly mow!

where did you buy the engine? under what part number?

Hi, me again! Got the engine and waiting on the air cleaner parts. Did your engine come with that cover at the top front that goes on the shroud? It says Kawasaki on it.

Well, you won't believe this one! Was just replacing the O-ring on the oil cooler to fix a leak and when I took it apart the embossed threaded area that the mounting tube screws into fell off. Guess this was my oil leak. Now looking at a new engine as I don't think it is repairable.

What size is the fuel line?

Just got a 27 hp to replace my 25 hp!! I don't see the oil send switch ?? There's not one one the new motor!! Looks like a small plate over the hole?? Should i take it off??? Hope someone knows HELP

starts but when I move sticks to go forward it dies

Where as the kawi motor and the JD motor are exactly the same if something should go wrong with the kawi DO NOT tell them you put it on a JD it voids the warranty. Yes its stupid but true.
