Re: (ET) intermittent noise



                 The Iron Man "Chassis Ear"®. Have used it numerous times. But there are some places you just can't use it. Like INSIDE an automatic transmission or trans axle. :(
                        The wireless ones are even nicer. I hope that they now have a USB output so that it can utilize the vehicle's entertainment system to listen in.
                       Some jurisdictions prohibit the use of headphones while operating a motor vehicle.Back in the day, I used a cassette adapter for a Walkman® to accomplish this.

There is an automotive diagnostic tool that allows you to place several sensors around the vehicle and listen to individual sensors until the sound is heard loud and clear.

         An audio recording would be most helpful.As a luminary in the automotive service field once put it, "There are two kinds of noises. The ones you kill and the ones that kill YOU. "

           He was referring to just how difficult tracking down the source of a noise can be.

I need help analyzing an intermittent noise coming from my E20 please.  It only happens when moving, then only in reverse, and only when the tractor is experiencing a load (backing up a grade, pulling something in reverse,etc), even then not always.  It is hard to locate the source as I have to be on the tractor driving instead of moving my ear around down low!  I had my wife back it up a grade as I crawled around it. It's coming from the rear (makes sense as there are no spinning parts up front other than 2 wheels).  Now, the sound is like putting an axe blade to an old foot pedal slow-spinning grindstone for sharpening.  Yeah, almost exactly like that.  Or to put it in context of the E20, as if the transaxle sheave is touching the frame and grinding away  (not happenin' though).  I thought about something metallic intermittently touching the disc brake rotor but the sound seems to be from the other side of the transaxle.  Gotta be inside the transaxl!
e I fear
.  Any similar experiences?

Mike

PS, as an update, yesterday I tried and tried to make the noise and nothing.  I have heard it up till yesterday several consecutive days. It is so ominous that I hate to even run the tractor when it's acting up; but yesterday, not a sound.
