Gear oil smell

[BigTone]

I cleaned the tractor with a heavy duty degreaser last year that really worked well but the rear end grease smell didn't really go away. I was thinking simple green or zep orange cleaner for the smell, any suggestions? Thanks Anthony

The sulphery odor might be coming from the inside out. As the tractor heats in this weather, the gear oil does make a odor. If an additional washdown makes no difference, you may need to live with it. Jim

Thanks Jim, I suspected that. My wife and I bought a new house and the neighbors are close, I'll probably have to keep it covered good from now on.

As Jim says fact of life. Most area have vents so as to not build up pressure so the smell comes out no matter what.

You don?t say if you have changed the gear oil or not. Much of the older gear oils had very pungent odors to them. If you find the odor is actually coming from within the gear case changing the lube oil may help. I would in such case recommend the diesel fuel flush that many on here say is a no no. You don?t say exactly what tractor this is but if you put about a third of the normal lube capacity in diesel in and add a quart of automatic transmission fluid. Then you should be good to drive it around 20 minutes or so with a few short burst at about half throttle in the highest gear. Drain that out and refill with new gear oil of the weight of you choice. The new oil should have a lot lower odor. Boy I was just down in Houston at an outdoor military museum on a 90 plus degree day. Some of that equipment with the military spec 90w sure has a distinct odor. Lol. Good luck and as always ...your mileage may vary.

My Mother would always say " you have been around Sinclair oil today haven't you?" That stuff did really have the sulfur smell! I can give you a solution though.....have a smell/taste destroying sinus surgery & then even you poo won't stink! And that is a fact, Jack!

I know the gear oil smell but I can't say I smell it when on my tractors. Would it be simpler to change the gear oil out for a synthetic or do they smell the same. I don't know just thinking out load.

what else smells like that? Manure, rotten eggs, dead animals. Look for abandoned bird nests or dead animals around your property. Seems like farm tractors soak up the manure smell. depending on use and where parked, the smell could be embedded in the tires or any soft materials on the tractor. the cows went 20 years ago for us, but the manure spreading tractors still smell--one has new tires and the smell stayed with the old rubber.
hopefully you are more sensitive to the smell than your neighbors.
