I have been looking for a DEF filter on my 8230 that is supposed to exist on the most recently built machines but since mine is an early build I'm not sure if it's there or not. I looked on CIH website and found the part number listed on the parts diagram but it doesn't show the location, any idea where to find it?

thanks

DEF filter is located in the dosing module which is under the steps to go up over top of the engine to the graintank. The dosing module is a square steel box with a black plastic cover on it. The filter is underneath it you have to remove the cap under module with 1 1/8 or 1 1/4 socket (can't remember which size). When you get cap off you can pull the filter out and push new one up in there and reinstall cap.

Isn't that a high priced filter? Are you replacing because of hours on the machine or are you getting an error code?

No codes yet, just wanting to find out where it is and if mine has one or not. Thanks IHHarvester for your insight.

IHHarvester is right. The DEF stands for diesel exhaust fluid. Also known as the urea. Deere did not add this till the full tier 4 that just came into production the last year or so. If your 8230 has the DPF which stands for diesel particulate filter it will add raw diesel to the filter to burn off the exhaust particles. The DPF sits right underneath the exhaust pipe. It is a oversize black cone. Honestly I don't think any 30 series had dpf's or also known as IT4. I could be wrong.

Thanks JVK, I was just looking for the in line fluid filter for the DEF to catch any particles in the fluid before causing further damage or blockage.
