john deere b transmission

travisbc · Jan 25, 2011

i just bought a nice john deere b and has a wining noise in transmission. a guy told me that its a bearing. is it very hard to replace them? he thought that is was a carrier bearing.

if your going in to the carrier and dont really know for sure what bearing it is you are best to replace all the bearings, most can be found at local auto parts stores with an cross reference manual. it would be a good idea to get yourself SM2004 from deere or another source to aid in your repair, has step by step instructions to repair and setup the transmssion and differential

I don't know if this is your first John Deere or not but in higher gears (5th. & 6th.) they almost all have a wining noise due to the square cut gears. Just wanted to let you know before you spent money you may not need to. (ask me how I know this :roll: )

I question whether this would be the problem or not. Sound more like noise transfer from the reduction gear. Not much you can do with whinning noises. You can rebuild the transmission and most of the time it is the lower cone type bearing that wear loose. Unless you have several hundred to spend I'd get some ear plugs....

For sure if you do it get the manual mentioned below.

I can just about gaurentee you that it will need all the bearings. Not a bad job if you have mechanical experience. You can work standing up and you don't have to split the tractor (unless you have to pull the differential ) it can stay intact self supporting.
The crazy thing about noises is that if bearings are bad and you go through it all the noise can even get worse ( not always)depending on old wear patterns. But I always rest assured that at least now I knew it was good in there and not ready to self destruct.

If it were me, I'd put up with the noise unless you're worried about tearing something else up. Be a good idea to mark the gears if you take it apart so when you put it back together, you can maintain the same wear pattern.

The primary reduction is probably the most forgotten and is the part that "runs the farthest"..
You will need to know what "worn" primary reduction
gears look like, to know what you are looking at, if you did open it up..
The bearings in the primary are most likely bad, if they have not been changed in recent memory..

I agree with Mike, once those gears run with worn bearings they are never going to be totally quiet again. Even if you replace all the bearings you will likely have some noise, but since you have looked at all the gears you know they are not going to disintegrate. You may be able to determine which set of gears is causing the noise by listening to what gears cause it, if it changes with tractor speed or engine speed, etc. My experience is that first reduction gears are big offenders and can look great and still make noise. Since the outboard bearing doesn't get a lot of oil it can be the first to go and cause problems. Good luck with it, not too hard a job replacing bearings.

Try changing the fluid and make sure you use the right weight oil.
