I'm late to this thread. Maybe the tractor in question is a different year than mine, but the diagram on the first page is not for a DK45.
I am also getting in here a little late with my two cents. I have a 2006 CK30HST that I bought new. I had the same problem with my r/front bearing giving out. I thought it was just a seal ,seeing oil on the the inner part of the front wheel. Pulled it into the shop and removed the wheel and axle housing only to find the seal was bad because the wheel bearing gave out. My dealer is 70 miles from where the tractor was so I went to the local New Holland dealer and guess what they had the bearing, seal, and o ring in stock. Looks like the N/H front ends are the same as a Kioti at least on a CK 30. It cost me 85.00 including new 80/90 wt gear oil and a pizza bought them lunch and they removed and installed the new bearing. I was surely happy camper.
