Replacing Hydraulic fluid

[bubbaboy]

I have a Kubota B7300 dsl and am doing my 300hr fluid change. The old fluid is out, the screen cleaned and all plugs are back in place. My problem-Is there a trick to opening the yellow oil inlet cap (behind the seat) to put the new fluid in? I've turned it at least 500 times and am not getting anywhere.
Are you supposed to pry it off? What gives?

Thanks for any help.

If it's anything like my NH, it just a rubber plug that pulls out.

Same here.. rubber plug on the 3130. It just pulls out.

No threads and you don't screw it out. Just a hard plastic or rubber plug with an Oring seal. Take a pair of pliers and grab it ,rotate and/or rock it left to right. Pull it out. Lubricate with oil or grease when you reinstall. Will make it easier to get out next time

The hydraulic fluid filler plug is hard to remove on my B7300 also. I found that if I wear leather work gloves I get a better grip on it and it is easier to remove.

Interestingly enough, I did the 300 hr service on my B7300 today, also changing the hydraulic fluid. The issue for me was removing the hydraulic inlet screen. Turns out the factory paint was so heavy on the "nut" it acted like super glue. After calling a guy I know who works for the dealer, I found out I just needed a little more elbow grease on the wrench to break it free. I was worried more of breaking the nut or stripping the threads until he verified it was a "left off" thread. At least next time this will not be a worry.
