Mazzotti MAF 230 hyd filter

[bl1951]

Does anyone know if you can clean hyd. filter on a Mazzotti 230 backhoe or if it is a replacement cartridge. If it is a replacement cartridge does anyone have a cross reference number for the original Donaldson filter # P171833 or the OEM # 210111700. I bought a used tractor with this backhoe and I am certain the filter has never been serviced. Also would be happy to know of a Donaldson dealer who might have the original filter. Thanks for any help.....BL1951
