I am interested in a few larger pieces of equipment, JD 8130/8230 and 9400/50 combine. I have read on combine forum that it might be advisable to check operating bearing temps with an IR gun. Sounds good, how/what do you compare values? Check numerous bearings and look for an oddball? Are these nominal values published anywhere? Is sampling oil and getting lab analysis worth the effort, or only if you detect foul smell or discoloration? I used oil analysis religiously in USN, but I don't know about cost/benefit in this case. I truly appreciate any and all feedback re these questions or these machines in general.
