I was just looking at the seal on a door for a 2009 BobCat CT450 which is really a DK50SE C. I think it might be the same cab but double check your year. The part is actually just called a rubber and is shown only as a small section, but Kioti P/N T4145-82521 if I'm correct. I can check with my parts place down the road because she might have mentioned yesterday that there was a new part number on that one, but they should still match up. That looks fixable on yours, but, here in Canada, that seal is about $55 CDN so maybe $40 USD. It is back ordered here at some places but available through others.I have a dk45s cab that the door caught on a limb and pulled out the door piston and has damaged the door seal. Does anyone know if that's repairable or a door replacement?
