Bobcat 753 hydraulics , boom will not go down, bucket wont tilt closed

[Jeff1941]

Hi to all, I have a 1998 bobcat model 753F. After installing a backhoe attachment,I had a hose with a leak. After replacing the bad hose,the machine worked fine. I removed the hoe and went to install the bucket. The boom will go up, but not down, and the bucket will tilt open, but not closed. All of the lites on BICS are green none are flashing. The hydraulic oil is full. Maybe there is air or dirt in hyd system? The auxilery hydraulics worked fine with hoe attachment. Any thoughts or solutions will be appreciated. Thank you. Jeff1941
