Cooler planetaries

[rumrocks]

Has anyone found an effective additive that lowers oil temperature in the rear planetaries on Deere sprayers. I do use synthetic oil and yes I do travel too long on roads fully loaded.

If it’s a 4830 do not over fill they heat with to much oil

years ago we added power up to a gearbox on a versatile 4750 swather, it was amazing how much it cooled
in the oil patch days we ran synthetic gear oil in the pumps when the oil co's worked the piss out of them , really helped
i am surprised a planetary would run hot ?
the planetaries on our rogator don't even get warm

Don't know the exact name but some red type of gear oil from Texas refinery in moose jaw my brother uses keeps the planetaries cooler on his 4730....considerably. ...

I don't even keep dinosaur gearbox juice around anymore. Swather knife drive gearboxes taught me that back in the 90's. I believe powerup is a bandaid that current synthetic gear oils have made obsolete. If your gearbox is still running hot with a 75W90 synthetic in it you have other problems.

Finally, I have an answer on this site! Spent a decade burning up rear planetaries and every oil burning itself black after 100hrs of use. Until I tried Lucas hub oil. 85w140. Planetaries ran cooler and I no longer needed to change the oil between engine oil intervals, it still looked great after 200 hours.

Thanks for the suggestion.

This might be Royal Purple.

Has kind of a Cult following. From Texas.

You can get it at Canadian Tire, Amazon, Jegs Racing.

About the most useful tool on my farm is one of those point and shoot thermometers.

Greatest thing for checking for hot bearings and gearboxes on haying or harvesting equipment.

You can do the whole machine in less than 5 min. Saves wearing out shafts and starting fires.

funny these manufacturers can get away this shit in this day and age . planetaries should go thousands of hours on an oil change ? this is not common on other sprayer makes ?

Oh come on......its a John Deere! It would never be an engineering problem, it must be the oil's fault! Or the Operator!

Maybe a Regulator is needed to force recalls for disasters in Ag machinery engineering, right bucket?
