- In this video we go over replacing the motor in a John Deere 757 Ztrak mower. This video also applies to 737 Ztrak as well. In this video we install a Kawasaki 25 hp twin cylinder motor and go over what needs to be swapped in order for it to work on the John Deere machines. Kawasaki builds these motors for John Deere. It is much cheaper, $800+ cheaper to use the motor direct from Kawasaki than it is to buy the 'John Deere' motor but you do have to swap a few things over. It is a very easy swap that requires basic tools and maybe a second person to help lift the motors.
This is the oil pressure sensor socket I used - www.napaonline.com/en/p/BK_77...
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.
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...
Roger they let me know it will ship separate . Thanks great video
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.
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.
excellent Video, Ty
I have the same mower and am
How do I change my fan from my transmission? Need your help
Hi, some questions.
Can i ask what model from carol stream you purchased for this swap? Was it the FH721D-S08?
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.
How's the new engine running? Power good?
where did you buy the engine? under what part number?
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
Hi, me again! Got the engine and waiting on the air cleaner parts.
