98 416C cat backhoe, what engine oil and filter, and capacity

Hi, I don't have my manuals anymore. What oil, and filter should I be using? What is the capacity and how often should it be changed? Thank You
ps, I have some cat filters that came with the machine but not sure what they are for so if I could get a oil filter number, that would be great. Also fuel, trans and hydraulic filters too. I guess I could check with the dealer when they open.
Thank you
