I seen too many round balers go up in flames, so got me a fire extinguisher and a heat gun.    My roller bearings were running cool on the right side with no chains, but the main sprocket on the left with the chains got too warm to hold my hand on it. 

 

Also the chains were very warm,  added 90w gear oil to the chains, but I don't like that because it adds fuel to the side of the baler.   I try to keep it very clean inside there if I can besides hay chaff I can't help that. 

 

I was running spray on chain lube, but I don't think it's getting the job done.  

 

 

I noticed a non-greasable roller bearing had some white stuff that had weaped out some time ago,  mighta been at install cause it wasn't fresh at all.

Good for you on being proactive....I use my laser thermometer to check for changes in bearings. I just keep aware for anything above the average. In so far as the chain lube....there’s two trains of thought, no oil and oil. I have auto oilers and they keep the chain moist with oil. There are folks that swear by dry chains with only occasional spray lube.

I've utilized JD aerosol chain lube on my rd baler chains for yrs. Several yrs back I owned a rd baler with automatic chain oiler that I thought chain wear was accelerated due to the automatic oiler.  I agree with Dawg with laser thermometer I get alarmed if a brg is considerably higher temp than the remainder of brgs.

What is y’all’s technique for laser if the bearings? Do you just pause in the middle of baling and do a walk around to shoot them all while running or do you stop the baler? 

Which bearings are the most likely (if any) to turn my baler from a pile of junk, into a flaming pile of junk?

ive got the BR7070 and all of the bearings except the main drive triple sprocket bearing run at 120F. The bearing behind the triple sprocket runs about 160F and it is brand new because it went sideways earlier this year baling straw. no damage to baler, very small fire on ground that was easily handled with the extinguishers i carry. 1 on tractor and 1 on baler: the refillable air charged type from buckeye. the full time firefighters call them silver bullets. add a cup of dawn and they are a beast on any type of equipment fire. the gear box runs hotter than i like (200F) so i'm gonna change the fluid and see what that does. hoping its not headed sideways...and its likely feeding heat to make that bearing warmer as they are only about 2ft apart.

 

i have been using 90w gear oil for the chains but just bought a can of the new wd40 specialist roller chain spray. gonna try it out soon.

What does the Dawn dish washing liquid do? I have a 2.5 gallon extinguisher on my baler and I am curious?

makes it foam so that you can put out oil/fuel/grease fires. plain water doesnt work so well on those and in certain situations makes it worse

Soaps are a 'wetting' agent.  Think of water not beading up as much, hence covering more area with a wetting agent involvement.  
 

I use car wash soap, seems I read where some kid did a science project (in California perhaps).  He used Dawn, car wash soaps, etc., seem car wash soap had the best effect.

 

Anyhow, 8 to 16 oz seems to be the recommended level (with 2.25 gals of water) and any soap is better than none (because of the wetting agent part).

 

One fireman recommended starting your own little fire and experiment to figure out what works best for YOUR situation.  The price of a bottle or two of soap, might be 'cheap', compared to what you might lose in a fire.  ;)

Forgot to add that I use 'farmerized' distilled water in my fire extinguishers, being I have a hard water well.  I just catch some water in a plastic bucket that comes out of the old A/C.  Depending on the weather, might take a day or two to accumulate 2.5 gals.  Wife's flowers have to do without almost distilled water and live with the hard stuff once in a while.  ;)
