Anyone have advice on cleaning water separator, it appears to be located in front of the radiator on the RK24, I have never done this type of procedure before and the manual is vague unless I am missing something.
Words of wisdom appreciated.

You are missing nothing - the manual is very poor.
On both my NH TC40D and RK55, the procedure has been to close off the fuel supply valve, remove and clean the bowl, clean/check and/or replace the filter element, reinstall the bowl, reopen the fuel supply valve, and bleed the fuel system - all easy stuff except bleeding air out of the downstream fuel lines. It was easy on the NH - one bolt on a "banjo fitting". It was more difficult on my RK55 mostly due to the terrible translation of instructions in the manual, but there is a bleed screw on the filter housing (the RK55H has both a fuel filter and a separator). I'm not sure of the procedure on the RK24, but it SHOULD be similar.
I looked at your owner's manual on line and saw no instructions on HOW to bleed the system. In fact, the picture on 5-13 on section "FUEL" has something labelled "filler cock", but the text refers to "filter cock"; the identical text is copied-and-pasted on page 5-14 on section "CLEANING OIL WATER SEPARATOR". Page 5-30 has 3 points about the "FUEL SYSTEM". But that's it - very little help.
So you are correct: per usual, the owner's manuals are horrible. Perhaps if you look at pages 5-12 and 5-16 of the RK55H manual online, you can get a general idea of how to do it.
Before you do this service, I have to ask the question - do you even need to clean the separator? Both bowls on mine are clear enough that I can see any water on the bottom (oil floats, water sinks) and can see how dirty the filter element is.

I hope this provides some help. If not please let me know Daniel Patterson

I'm pretty sure the water separator has a red ring that will float on top of the water. Water is more dense than fuel and will sink to the bottom. The density of the ring is somewhere between the densities of the water and fuel and will therefore float at the interface between the two. Easy way to see if you have water in the bowl. If the red ring is sitting on the bottom, you're good.

Wow you guy's are Helpful as all get-out, Markie61- thanks for confirming that I am not on the dull end of the spear with my question and I will look at your recommended info, RK tractor Guy- it is a pleasure to make your acquaintance and thank you for the info which I will put to use, synmat68- again thank you for the help, I have had a look at the separator and the red ring is dead at the bottom confirming no significant amount of water in the total system but I am pursuing due diligence for future actions (planing ahead is planing to succeed).
I truly appreciate all of the helpful info that I get from you folks and hope to be of help to others and perhaps you in the future.
y'all have a great night and wonderful tomorrow.
