When I need to look up a part number, I usually go to MEI's site. An additional gripe I have on Kioti's site is that they seem to leave old models behind. I tried to send them an online query about grease nipples for my loader and they first had me fill in a form with my tractor and loader models. Well, guess what?! The DK45SC wasn't listed as an option, nor was the KL451 loader...I had to indicate DK45SE and KL401 to get it to accept my query...oh, and after more than a week, I haven't heard back from them.
