So guys I decide to go forward whit the project to replace the K46BR3 on my X300 with a K66Y.
I know some of you have objection and concern about the warranty of the tractor, please be advise I’m doing that for me anddo not advise anyone to do it.
If you decide otherwise be advice that I strongly recommend that you wait until your warranty expired.

I receive it this afternoon, NOS K66Y ($300.00 CDN at my door step)
I inspect it and everything seam OK at first look, tomorrow I will test it on bench.
First I will replace all the oil and make the purge procedure, like usual I will document my progress all along.
according to jdparts.deere.com the hitch plate is 125.00 US. but it would give the ability to also add the sleeve hitch, which the X300 hitch does not.

That's too bad the oil resevoir was cracked. Looks good though. Of course I know the tractor is going to move faster than the shaft was moving in the video.
The k66Y pulley come with a different diameter and thickness, so to keep the original ratio (speed) between the motor and the tranny I have to install the K46 pulley
At the same time keep they original belt that come with the X300
The pulley of the K66Y is smaller (4.27) (the K46 is 4.9) so theoretically they input shaft will go slower and she is larger so that will mine to change the engine pulley to have a matching set for the belt.
I`m thinking that your new 66 needs to be driven at it`s original design speed in order to perform properly. If I`m following correctly, you have installed the larger stock pulley from your 46. which will slow down the impeller. Assuming that both engine drive pulleys are the same, won`t this translate into lower ground speed and perhaps decreased power / hyd efficiency ?

The spec input speed of the K66 is 3400 RPM and 3000 RPM for the K46
So the way I did it they input shaft will turn 400 RPM less It is better then going to fast, slower a bit will not brake the internal part in the tranny but going faster is always risky
