RX7340 50-hour oil change

[cutthroat]

The other day rolled over 50 hours on my 7340. Manual states need to replace the hydraulic filter and engine oil and filter at 50 hours. Looking under the tractor, the hydraulic filters are in a totally different location and there appears to be one small one and one large one now. Unfortunately looks like they painted them so can't get any part numbers off them. My tractor came with a new oil filter for some reason, and this matches the same part number of the 7320. The manual states CJ4 oil is recommended. Does anyone have experience using the newer CK4 oil? From my research it is just a better more modern version and is recommended for newer Tier 4 diesel engines and appears to be backwards compatible with CJ4. Will reach out to dealer to see if they have the correct hydraulic filters. Going to get and try the "Vac Trac" to see if can minimize hydraulic oil loss during swapping filters.

Finished my 50-hour service today. Ordered these filters from my dealer. Couldn't determine the part number on the factory ones because they had been painted over. The small filter is part # TD24-0257A, the large filter is part # TG14-0518A. What was odd is the large filter came with the housing that the filter screws on to that is normally installed on the tractor. Dealer told me that is all Kioti could currently offer. This filter was so tight onto this housing that I actually dented the filter a little just getting it unscrewed. Had a hell of a time getting the factory large filter off the tractor as well. Broke a rubber strap wrench getting it off. Using the Vac Trac worked great, no spilling of fluid except what was in the filter. For the engine oil I used Rotella T6 15W40. I was looking to replace the air filter as well. This too looks to be different than what the RX7320 used to use. The label says Donaldson P647862 but the Donaldson website doesn't show this as a valid filter. So still trying to locate some spare of these.
