My L245 has a cartridge style oil filter. I cannot find a replacement. I have scoured the Internet, talked to dealers, emailed Kubota Corp. to no avail. All of the filter companies and Kubota themselves call for a spin-on style. Has anyone ever heard of this? The filter that came out is metal clad #5514 140F3G. There is no manufacturer name, only MADE IN USA. I have checked this number everywhere, no luck. Any info or suggestions will be appreciated.
